The 10 Steps
Construction is broken down into the following 10 steps which are common to all of my shed plans…
6) Raise walls
7) Open door
8) Roof structure
10) Shingle roof
These plans include dimensions to build a wooden storage shed or garden shed in 21 different sizes from 8×4 to 12×20 as listed across the top of Table 1.
Once you have decided what size shed you want to build, purchase the number of items shown below your chosen size in Table 1.
Ask your building supply store for their estimate for fasteners as you are purchasing the lumber.
There are four places where building an 8 wide and a 10-12 wide shed differ.
These details are explained in full in the appropriate step.
I just want to point them out so you will be aware that most of the procedure is the same.
- 8 wide sheds use 2×4 floor joists, 10-12 wide sheds use 2×6 floor joists
- You should should add some 2×4 blocking where the large and small pieces of plywood join on 10-12 wide sheds for extra floor strength
- You will need to splice a 3 to 6 inch piece of scrap siding at the top of the gable end truss on 10-12 wide sheds
- On a 10 wide shed door you will need to change the spacing and add one additional upright to the inner door frame
Otherwise the differences are the length and number of components you will need, as detailed in Tables 2 and 3.
When a Figure show a letter (“A”, “B”, “C” etc.), you can find this dimension in table Table 2.
Table 3 shows the number of floor joists, wall studs and trusses you will need based on the length of the floor/wall your are building. For example if you are building a 12 foot long floor, you will need 10 floor joists. But if you are building a 12 foot wall you will need 7 studs for that wall.
But first I have several recommendations that will save you time, money and effort.
Buy 2×4 Precut studs if you can find them
The first is to use 2×4 precut studs if you can find them. Precuts are 2×4’s that are 92 5/8 inches long as opposed to the normal 8 ft.Use them for wall studs and trusses and you’ll save 25 to 50 cents per board.
If your building supply store doesn’t carry them then just use full 2x4x8ft lumber.
Use screws instead of nails
The second thing I suggest is to use screws instead of nails. Screws have better pulling power and can pull a twisted board into place better than a nail can. Screws also have better holding power. This means they will hold your 2×4 frame in place tighter and longer time than nails can.
Drill 1/8 inch pilot holes
Whether you’re using screws or nails I recommend drilling 1/8 inch pilot holes when assembling the frame because this will prevent splitting the ends of your boards. Also your nails or screws will not go astray because of the grain of the wood, nor will you have a problem with knots.
This might add a little additional time to your shed building project but it will make construction much easier for the novice builder. But if you have a nail gun then by all means use it. Just be careful to not split the ends of your wood.
Use pre primed composite hardboard siding
Using pre primed 4×8 sheets of composite hardboard siding will allow you to build your shed in the least amount of time and for the least amount of money. And composite siding holds paint much better than natural wood.
This will save you the step of applying a base coat of primer and your paint job will last longer. Which means you won’t have to repaint your shed as often.
Make your own trim
Make your own trim from sheets of composite hardboard siding. You can buy 4×8 sheets of the same siding but with no grooves, and rip them into 2 1/2 inch strips with a table saw.
If your building supply store doesn’t sell no groove siding then just use regular grooved siding. But then you will have to spend a little additional time cutting around the grooves if you want your trim to look its best. Two sheets of no groove siding will give you more than enough trim to build up to a 12×20 shed.
You don’t absolutely need a table saw. You can cut the trim strips with a circular saw but your cuts will not be nearly as clean as with a table saw. In fact I suggest that you borrow or rent a table saw if you don’t have one because it will give you a much cleaner finished shed.
Here’s a list of tools you’ll need to build your shed. If you don’t have some of them likely you know someone who does who will let you borrow them for a week end or two.
- Claw hammer
- Tape measure and pencil
- Speed square
- Chaulk line
- Tin snips
- Step ladder
- Utility knife
- Hand saw
- Extension chords
- Circular Saw
- Electric drill, 1/8 inch drill bits and philips screw driver bits
- Router with a 1/4 inch bit and a follow collar
- Table saw
- Caulk gun
- Roller and cage (or spray gun)
Now before we get started with the actual building I have a couple of disclaimers…
You might need building permits to build a shed in your area so check with your local building department before you get started.
The construction techniques in these plans might not meet building codes in your area as they vary around the country. So your building department might ask you to make a few changes to these plans.
But the building departments are usually very helpful and will let you know exactly what their requirements are.
Even though I have build thousands of sheds like this with no problems, I make no guarantees about the structural integrity of this shed.
Step 1: Foundation
The main function of your sheds foundation is to transfer the weight of your shed and its contents to the ground.
But it also serves several other important functions.
- It provides a way to level your shed if necessary
- It protects your sheds floor against moisture
- And it protects your shed against termites
- When necessary can protect your shed from movement resulting from frost heave, water or wind.
4 General Types Of Shed Foundations
- Simple skid foundation on earth, gravel or concrete blocks
- Wood and concrete pier foundation
- Concrete slab which serves as both a foundation and floor
- Floor-less foundation when you want to build a shed without a floor
Simple Skid Foundation
A simple skid foundation consists of two pressure treated runners laid parallel on the ground.
This is a lot cheaper than a concrete slab and has the added benefit of keeping your shed portable should you ever want to move it in the future.
Pressure treated wood is usually some shade of green as a result of it’s chemical treatment and is labeled with a tag to identify it as being pressure treated.
See Table 2 and Figure 2
Cut your skids to length using measurement “B” From Table 2 in your shed plans. Don’t trust the factory cuts because large pieces of dimensional lumber are usually ¼ to ½ inches longer than stated.
Select a location with adequate drainage then clear and level the building area.
You can lay the skids directly on the ground, on concrete blocks, or on a bed of gravel.
Their spacing will differ depending on the width of the shed you’re building. The measurement for the skid spacing is measurement “D” in Table 2, and is shown on Figure 2: Floor Dimensions and Layout.
If your site is fairly level you can lay the skids directly on the ground.
Don’t worry about getting the skids perfectly level at this point because you’ll make the final level when the floor frame is complete.
Shed Tie Downs
If you expect to have a problem with your shed moving from frost heave, water or wind, or if it’s required by building codes in your area you can tie your shed down.
I’ve already covered shed tie downs in these other posts…
- Why you might need to tie your shed down
- Cheap home made shed tiedowns
- Frost heave and your shed foundation
If you need to then just skip over to my shed tie down posts to see what you need to do before you begin the next step, which is building the floor.
Wood And Concrete Pier Foundation
The location, number, size and depth of the piers might be dictated by building codes. It will also be a function of the weather in your area. You might need to dig down below the frost line to get the best results.
In the absence of building codes and with moderate weather you should have a pier at each corner, about 12 inches in diameter and going down 24 to 36 inches into the ground. In addition you will need a concrete block support every 4 feet or less in between the piers.
Move the skids out of the way, dig your holes and put the skids back in place. Measure from the bottom of the skid to the bottom of each hole and cut a pressure treated 4×4 pier 4 inches less than this measurement. This will allow enough room for concrete to flow under the bottom end of the pier to prevent wood to earth contact. Just an extra precaution.
With the 4×4 piers hanging down in the empty holes, re square and re level the skids. When they are correctly positioned then fill the holes with concrete up to ground level and let them dry for a day or two.
Before you sheet your floor you can add some metal straps or H25’s to tie the skids to the floor joists for extra security.
Foundation for floor less shed
You don’t necessary need a floor in your shed as long as you have a suitable foundation. Here are 2 foundation options if you want to build without a floor.
- Pressure treated wood with post and concrete piers
- Concrete stem wall
It’s important that you build the foundation tall enough to keep the siding away from the ground where moisture and termites will damage your shed. I recommend at least 4 inches of distance between the ground and any untreated wood. Like the bottom edge of the siding.
One way to accomplish this is by increasing the stud length. This will reduce the lower siding overhang and make your walls taller. I recommend a minimum of 1 inch lower siding overhang to prevent water from seeping under the bottom plate.
This means your foundation needs to be at least 5 inches above ground level.
How deep you go will depend on building codes, frost level and if you will have animals trying to dig under your foundation to get in or to escape.
Pressure treated wood with post and concrete piers
This is an example of a foundation frame for a 12×16 shed.
Install post and piers
And make sure it’s level and square then secure the wood perimeter frame to the uprights with galvanized metal straps.
Don’t worry about tying the individual perimeter pieces together because once you tie the shed in, that will tie all the foundation pieces together.
This graphic shows a 5 1/2 inch tall frame with 1 inch siding overhang and 4 inch gap from ground level.
As an option you can install more pressure treated wood below ground level to keep animals from digging under the walls.
Concrete stem wall
Another option is to build a concrete stem wall.
Build the outside of the stem wall the same size as your shed.
Attach with j-bolts
The top of the stem wall should be 5 inches above ground level minimum, which makes a 4 inch gap from the ground to the bottom of the siding when using a 1 inch siding overhang.
Step 2: Floor
If you live in an exceptionally wet area or have a major termite problem you might want to use pressure treated wood for the entire floor including the skids, the floor joists and the plywood sheeting.
This will add to the initial cost of your shed but it might also save you money in the long run because a floor built with pressure treated lumber will last longer in these areas.
Prepare your materials… See Table 1 and Table 2: Get the number of floor joists you will need from Table 3, and the cut length for the band boards and floor joists and skid spacing from Table 2.
See Figure 2: Cut your band boards and floor joists and lay out the band boards for 16 inches on center and drill two pilot holes for each 2x4joist, or three holes for each 2×6 joist.
If you are building an 8 wide and using 2″x4″x92 5/8″ precuts then you can use them here without any cutting. They will be 3/8″ short but this will be split in half to 3/16″ on either side when you cover the floor with plywood. You will save a few dollars over 2″x4″x8’ers and no one will be the wiser.
10 and 12 wide sheds use 2″x6″ joists so you will have to cut them to length.
Assemble the frame: Lay the joists out on top of the pressure treated skids, spacing them about 16 inches apart.
Attach the band boards to the joists with two 3 inch screws or 16d nails at each joist.
Attach the skids: Position each skid as per measurement “D” from Table 2. Then drill pilot holes and toe nail both sides of the floor joists to the skids with 3 inch screws or 16d nails.
Except the front and rear joist.
Leave these two free so you can manipulate them to match the outside edge of the plywood sheeting as you nail it.
Square: Check the square by comparing diagonal measurements across the floor. Slid a skid back or forth until the measurements are equal.
Now the floor is square.
Level: Level the floor in all directions with a builders level. Add or remove a little dirt or gravel under the skids until the floor is level.
If necessary place a concrete block under each skid every 48 inches or less. Add blocks or wedges between the blocks and skids until the floor is level in all directions.
Recheck the square by comparing the diagonal measurements again.
Any extra effort you spent now to carefully level the floor will pay off when you start sheeting the roof. If the floor is not level, the roof sheeting will not fit properly and you might have to re-level at that time.
Tie downs: If you want to attach tie downs to the floor of your shed, now is the time. Attach them to the floor joists rather than the skids for an extra measure of security.
Nail the sheeting: Lay your best sheet of plywood along the front of the floor frame.
Square it up to the front corners and rim joist and nail along the front edge. Check the side edges for square along the frame and nail every 8 inches with 8d nails.
Repeat with the second and third sheet, putting the worst sheet at the back of the floor.
Extra blocking on 10 & 12 wide floors: If you’re using regular CDX plywood as opposed to tongue and groove you should provide some extra support where the full pieces of plywood meet the cut pieces.
To make these blocks cut 12 inches off the ends of some of the 2×4’s that you will be using for studs. You will need one less than the number of floor joists you have. These blocks will fit loosely, but that’s ok.
Attach them to the underside of the plywood joint with three or four 2 inch screws. Leave about half of the block exposed.
After you nail the smaller pieces of plywood in place then put screws on the other side of the joint to match.
Nail the center of your sheeting along the chalk lines every 8 inches.
Frequently asked questions
How strong is this floor?
My standard floors are strong enough for almost any application. I have a 24×20 shed (garage) floor built with 2×6’s at 16 inch O.C. and 4×4 skids at 48 inch O.C that I have been parking 2 full sized pickups on for the last 5 years, and the floor is still sturdy.
How can I make the floor stronger?
- You can make the floor stronger by putting the skids, blocks and joist closer together. 12 inch O.C. for the joists is about as strong as you can get. Put a few more skids underneath and more blocks under the skids making them closer together will add a lot of strength.
- Then you could use larger joists, like 2×8 or 2×10.
- And finally you can add another layer of plywood or 2 on top of the existing one.
Step 3: Trusses
- Read this post first if you want to use a ridge board in your shed
- Read this post if you want to change the roof pitch to 4/12 or 5/12
Make the trusses now because you’ll need two of them to build the gable end walls in the next step.
It’s important that all your trusses be the same height and width so that the ridge line of your new shed will be symmetrical. You can do this by making a simple jig.
Now cut two small pieces of wood and screw them to the outside of these marks. Then screw this jig assembly to the floor.
Prepare your materials: Measure and cut the pieces for the trusses. Use a speed square to mark the angles.
Drill a pilot hole in one of the pointy ends of every other truss piece so you can toe nail them together at the top joint. Also drill four pilot holes in both ends of the collar beams.
Toe nail the top joint with a single screw through the pilot hole.
Position a collar beam parallel to the jig and screw it to the truss with four screws on each side.
Make a pencil mark on the floor along the top of the truss so you can compare the rest of your trusses to this mark as you build them. If a truss is off significantly you will know it immediately.
After you have built all the trusses you can double check them by standing them up on end and measuring the distance from the floor to the peak of the truss. If they are all equal (or close enough), then you are finished and can disassemble the jig.
If some of your trusses are slightly off, don’t despair. If you use them properly this will not be a problem. Simply use the shortest pair of trusses to build the gabled ends with. Use the single tallest truss in the center of the shed. Use the next tallest pair, one truss on either side of the center truss. Use the last pair next to the gable ends. This way the roof will still be symmetrical and you won’t not have to waste or rebuild the less than perfect trusses.
Step 4: Walls
You will build all the walls directly on the empty floor.
- Read this post first if you want to build your shed with 8ft wall height.
- If you’re going to build your shed on a concrete slab read this post to learn about anchor bolt placement and to find out how to make your shed 3 inches taller.
You’ll want to build the shorter walls first so you can move them aside and use the floor space to build the longer and heavier walls in place. Here I’m assuming the gable end walls are the shorter and therefore lighter walls.
If not go to Step 4b and build the sidewalls first, move them aside, then come back here to build the gable end walls in place.
4a: Gable end walls
See Figure 4a and Table 2:
Measure and cut the wall studs and plates for the gable end walls. Layout the top and bottom plates at 24” O.C. and drill two 1/8 inch pilot holes for each stud.
Frame The Gable End Walls:Lay the wall studs on the floor spaced 24 inches apart and attach each stud to the top and bottom plates with two 3 inch screws or 16d nails.
Place Spacer Under Truss: Lay a truss on the floor touching the top plate with the collar beam facing down and slide a 1/2 inch spacer underneath the collar beam.
This will bring the truss up level with the top edge of the top plate.
Attach Truss: Drill 1/8 inch pilot holes through the outer ends of the top plate and secure the tips of a truss to the top plate with 3 inch screws.
The truss and top plate should be flush at the top edge of the top plate.
This screw is not for strength, it’s just to keep the truss in position until it’s nailed to the siding.
Check for square by comparing the diagonal measurements.
Sheet The Walls: Make sure the siding is square to the frame with 4 inches overhanging below the bottom plate.
Nail with 8d galvanized nails every 8 inches.
Snap a chalk line along the center of the top and bottom plates to identify those nail lines, and snap another line across the top of the truss and trim the excess siding.
Also trim the ¾ inch lip overhanging one edge.
Attach Handles: Attach scrap pieces of 2×4’s to the wall about knee high with 3 inch screws to make the walls easier to move.
This way you can stand the wall up vertically and have more control when you are ready to attach it to the floor and to the other walls.
For 10 & 12 wides only: If you’re building 10 or 12 wide gable end walls you’ll need to splice a three to six inch scrap of siding to the top of the truss.
This is because the 10 and 12 wide sheds are also a little bit taller.
Line the grooves on the scrap up with the grooves on the end wall and nail it in place.
Build The Second Gable End Wall:
If you’re going to put a door in this wall then proceed to Step 5 for instructions on how to frame a door into this wall.
Set this wall aside to make room to build the sidewalls.
4b: Side (or eave) walls
See Table 2 and Figures 4b, 4c, and 4d:
The side walls have different measurements than the gable end walls. Measure and cut the wall studs and plates per Table 2 and Figures 4b, 4c, and 4d. The studs on these sidewalls are cut with an angle on the top end and the length measurement is at the short side of the angle.
Make sure you build the sidewalls with the short side of the stud on the outside of the wall where the siding will be nailed. You do this by laying the studs down on the floor with the short side up in all cases.
Installing a door in a sidewall
If you are going to put a door in one of the side walls then proceed to Step 5 for instructions on how to frame a door into this wall. Build the blank wall first then build the door wall on top of it.
See Figure 6: Layout and drill pilot holes:
Layout the top and bottom plates at 24” O.C. and drill two 1/8 inch pilot holes for each stud. These plates are 7 inches shorter than the overall wall length because they will sit inside the gable end walls. So when you lay these side walls out, the end studs will be 3 1/2 inches closer to the next stud than with the gable end walls as per Figure 6.
Attach the bottom plate: Lay the wall studs on the floor (with the short side up) spaced about 24 inches apart.
Attach each stud to the bottom plate with two 3” screws or 16d nails.
See Figure 4c, Spacer detail: Before you attach each stud to the top plate put a 1/4 inch spacer below the end of the stud to raise it up so that the the stud will be in proper alignment with the corner of the top plate so that the siding will lay flat.
Lay a scrap of wood along the stud extending past the top plate to double check that this spacing is correct.
Sheet walls: Make sure the siding is square to the frame with a 4 inch overhang at the bottom plate.
Snap a chalk line along the center of the top and bottom plates and along the outermost two studs to identify those nail lines.
Nail with 8d galvanized nails every 8 inches.
Snap a chalk line, then trim the ¾ inch lip overhanging the ends. There will be no overhang on 10 wide ends.
Top Cut Line: Measure and mark from the bottom of the siding and snap a chalk line to mark the top cut line.
Cut this excess siding off which will leave a 3 1/2 inch overhang at the top plate.
Build the second sidewall: Leave this finished wall in place and build the next wall directly on top of it.
Now that all the walls are complete you might want to paint the walls and trim while you can work on them laying horizontally. They will be much easier to paint this way.
Step 5: Build The Door
This door construction method saves time and materials because you are using the materials cut out from the rough opening that would otherwise be thrown away.
You will make an outer frame which is built in the wall and the inner frame which is the actual door. You will frame and sheet these two simultaneously.
Later in step 7 you will cut the door out.
This is the most complicated part of building your shed. It’s not difficult, it’s just lots of details. But if you follow the steps closely you will have few if any problems.
There are 2 places where you can get in trouble here
- Not properly locating your cut lines before you nail your siding in place.
- Nailing the door to the bottom plate so that it will not open.
Otherwise just follow the steps for a strong and reliable door.
You can put the door in either the gable end wall or in a sidewall. The only difference is which king stud you will use.
Door on gable end
Door on sidewall
Just remember to build with the short side of the angle up toward the siding. Otherwise there is no difference in the door construction.
But if you make double doors you will have the additional width without the potential door sagging problem.
I will handle double doors in a separate post.
If you plan on using your shed for motorcycle parking then you might want to make the door about 60 inches wide. You might even think about adding a second door to make the shed drive through.
Wider or narrower doors
These instructions will make a door with a rough opening width of 43 inches. This is usually big enough for most large items like wheelbarrows or lawnmowers.
To make the door wider or narrower just adjust the length of the door header to give your desired rough opening size then add or subtract the same amount to the horizontal cross pieces and horizontal trim pieces.
You can place the door anywhere on any of the walls you like. However I recommend that you place it on some increment of 12 inches. Then the location of the vertical uprights are covered by Figure 5b.
Otherwise just add an additional vertical upright to the inner door frame where the siding breaks.
Make the outer door frame
This extra half inch makes the total width to 3 ½ inches, the same as the height of a 2×4.
Make the inner door frame
Put the spacers loosely inside the outer frame, 2 into both top corners and one along the side of each bottom corner. These are to keep the inside door frame from shifting until you get it nailed to the siding.
Measure and cut two cross pieces and three uprights. Lay all the pieces in the frame to check the fit.
Measure and attach the two center cross pieces half way top to bottom..
Verify that this assembly lays flat and is not warped in any direction.
Install the truss and remember the ½ inch spacer below the collar beam.
Check for square by comparing diagonal measurements.
Measure and record the distance from the center of the middle stud to the inside edge of the rough opening in both directions.
These measurements will locate your vertical cut lines after the siding is nailed on.
Put a single nail in the door frame’s bottom cross piece. But don’t nail into the bottom plate because doing so will nail the door shut.
Put a single nail in the center door cross piece and top door cross piece, and in the top plate.
Put a nail at the outside ends of the top and bottom plates.
Then put one nail into the end of the top and bottom plates. Snap a chalk line along the top and bottom plates and along the top of the truss where you will trim it.
Nail across the top plate only, do not nail the bottom plate at this time. And nail the outside studs and along the truss inside the chalk line.
Locate your cut lines
Snap a chalk line on both these marks. These are your two vertical cut lines.
Measure from the top of the siding to the mark you made ½ inches above the bottom of the door header and transfer this measurement to both ends of the wall and snap a chalk line. This is your horizontal cut line for the top of the door.
Measure from the top of the siding to the middle of the door center cross piece as evidenced by the nail heads. Transfer these measurements to both sides of the wall and snap a chalk line.
Now you should have:
- Two vertical chalk lines
- Four horizontal chalk lines
- Plus the chalk lines for the truss
Inner door trim
Measure and cut two vertical pieces to run from the bottom of this piece to the bottom edge of the siding. Nail these ¾ inch from their inside edges from top to bottom to within two inches of the bottom plate chalk line.
Position the middle piece of trim so that it’s centered on the chalk line and nail it down the middle.
Position the bottom piece of trim so the lower edge lies on the bottom plate chalk line and nail ¾ inches from its top edge.
Outer door trim
Lay a piece of trim horizontal along the top two spacers and another piece vertical along the other three spacers and pull them tight into the spacers.
Measure and cut the vertical piece of trim so that it extends between the bottom of the siding to 7/16 inch above the top edge of the top horizontal trim, as allowed by the spacer. Nail this in place.
Move the three spacers to the other vertical trim piece and measure, cut and install the same way. Then measure, cut and install a horizontal piece across the top of the two vertical pieces you just installed.
The door trim is now complete.
Step 6: Raising And Attaching The Walls
Now its time to attach the four walls to the floor. If you skipped ahead to step 11 to paint the walls then you have already moved them off the floor and onto the ground.
If your side walls are still laying on the floor, then move them about a foot from the back edge so you’ll have sufficient room to work.
Set the back gable end wall vertical on the edge of the floor and center it from side to side.
When it’s in the correct position attach it to the floor by nailing through the siding and into the floor frame about two inches above the bottom edge of the siding with 8d galvanized nails every 8 inches.
Cheating when necessary…
If a wall doesn’t line up with the floor then put a car jack under the floor and raise it up to fit the wall. Nail that part of the wall in place then move the jack.
Do this at any place where the floor doesn’t meet the wall.
Remember this cheat when you apply the roof sheeting. Put a jack under a corner and raise it up till the roof sheeting comes in line with the truss. Then nail that piece down. Do the same with the rest of the pieces. Experiment with jacking different corners or walls until you get the results you want.
After the roof is sheeted then go around and re level the floor.
If your shed is slightly out of square at the end of all of this, don’t worry as it will not be enough to notice. This is the real world way to make all the pieces fit together.
In my shed building business I have special pulling straps and jacks for this purpose because sheds never come together perfectly without a little “assistance”. But any old car jack will do.
Put a 16d nail in the center of the back of the wall and add a temporary 2×4 brace to the ground if necessary.
Stand the first sidewall and slid it firmly into the bottom plate of the end wall.
Make sure the corner studs are tight together from top to bottom and nail through the sidewall siding into the end wall corner stud from top to the bottom.
Then nail across the floor about 2 inches from the bottom edge of the siding.
Raise the other sidewall and nail the corner joint and across the bottom of the siding into the floor frame.
Move the last gable end wall into place and nail up and down the corners then nail across the bottom.
Which ever wall contains the door, don’t nail across the bottom of the door because that will be nailing it shut.
Remove the carrying handles.
Now it’s starting to look like a shed…
Step 7: Finish The Door
I recommend using 1/4 inch carriage bolts to mount the hinges and latch because they can not be backed out like screws can.
Plus they hold much firmer and will help reduce future door sagging problems.
Router bit: You’ll need a straight 1/4 inch router bit available from any hardware store.
Router collar: You’ll also need a router collar with an inside diameter slightly larger than 1/4 inch.
It will consist of the collar and a threaded ring to hold it to the router base.
You can typically purchase them individually or in a set.
Adjust the cut depth: Adjust the cut depth of the bit to the thickness of the siding plus the thickness of the trim, plus about 1/8 inch extra.
If you are using typical 7/16 inch siding that will add up to 1 inch.
See Figure 7, First router cut: The gap between the inner and outer door trim will guide the router collar as the bit cuts through the siding.
Start at the bottom of the side where you are installing the hinges and pull the router through the gap between the trim up to the top and about half way across the top of the door.
Make sure you cut well past where the hinge will be mounted so that it will not interfere with the router base when you start the second cut.
If you are not cutting through the siding then set the cut depth a little deeper until you just graze the 2×4 frame below the siding.
If your depth is set a little too deep it will not hurt anything. You will just have to work harder because you are cutting through more wood.
Mount the hinges: Locate where you want the hinges and drill ¼ inch holes for carriage bolts.
Use a long drill bit because you will have to go through 1 inch of trim and 3 ½ inches of wood.
Mount the hinges by driving 5 inch carriage bolts into the holes.
Place a second ladder inside the shed and climb inside. Install the washers and nuts and remove the door spacers.
Second cut: Finish cutting across the top of the door where you left off and cut and down the latch side to the bottom edge.
Open the door: Open the door and inspect your work.
If you located your cut lines correctly you will have an even half inch reveal all around the door.
Mount the latch: Locate where you want the latch to go and drill ¼ inch holes. Mount with carriage bolts.
Remove bottom plate: And finally, use a hand saw to cut the bottom plate out of the door opening between the door frames.
Step 8: Install Trusses and Frame The Roof
- Read this post first if you want to include the optional 3 1/2 or 5 1/2 inch overhang on all 4 sides
You should also nail through the sidewall siding into the ends of each truss to secure the roof structure to the rest of the shed.
Hang trusses: Hang the trusses upside down between the walls with each end resting on the top plate directly over a wall stud.
For aesthetic purposes only: Make sure to hang the trusses so that the collar beam on all trusses face the same direction… Either facing to the front of the shed or to the rear.
Install trusses: Stand the first truss upright and center it over a stud.
The wall studs and trusses are both 24 inch on center so just align the end of a truss up with the stud under the top plate and it will be in the correct position.
Make sure the truss is pushed tight against the siding and run a 3 inch screw through the bottom plate into the truss on both sides of the stud.
Do the same for this the rest of the trusses on this side.
The other end: If the other end of the truss doesn’t fit tight against the siding you can hook the ends of a cargo strap over the siding on either wall and gently pull the walls together until they fit tight to the ends of the truss.
Then run a 3 inch screw through the bottom plate into the truss on both sides of the stud like before.
Repeat for all trusses.
If you want to add 3 1/2 or 5 1/2 inches of overhang then read this step now. Continue below for no overhang.
Install the roof sheeting: Begin installing the roof sheeting with a full 8 ft sheet aligned at the top edge of the truss and put a single nail in the outside corner at the top of the truss.
Start the edge of the sheeting at the outside edge of the end truss.
Split the truss with the opposite edge of the sheeting and nail into the truss at the top corner.
Repeat for the rest of the large pieces of sheeting on the first side.
See Figure 8: Measure and mark the truss spacing for the rest of the trusses and nail with a single nail at the top of the truss at 24 inches on center.
Measure the end truss spacing from the outside edge of the end trusses to the center of the closest truss, not including the siding (from the joint of the siding and the truss).
The inside trusses are measured center to center.
Stagger the seams: Nail the large sheets for the other side along the top of the trusses only, but stagger the seams if possible for a stronger shed.
Nail bottom edge: Check that the bottom edges of the sheeting are properly aligned with the trusses. The edge should align with the edge of the outside trusses or in the center of the inside trusses.
If they don’t align properly that means either that the floor isn’t level or the walls are not square.
But don’t be alarmed if they aren’t properly aligned because that rarely happens.
The cure is to put a jack under one corner of the shed and lift it until the sheeting comes into proper alignment. If jacking makes it worse then you are lifting the wrong corner of the shed. Move your jack to the adjacent corner and try again. When a piece of sheeting lines up properly then nail it into the truss below.
Continue jacking different corners of the shed until you get all the pieces of roof sheeting in proper alignment and nailed in place.
You might have to re-level or re-block your shed at this point.
Snap a chalk line to identify the underlying trusses and nail the sheeting in place with 8d nails every 8 inches. Put plenty of nails at both edges of the sheeting, particularly where the sheets meets at a truss.
Secure siding to trusses: Nail two 8d nails from the outside through the sidewall siding into both ends of each truss to further secure the roof structure to the rest of the shed.
Finish sheeting: Stagger and install the bottom row of roof sheeting. You should have a 2 inch overhang on the eave sides and nothing at the gable ends.
Step 9: Install The Trim
See Figure 9 for cut dimensions
Cut (6) pieces of trim item A and (6) pieces of trim item B. The only difference between the two is the direction of the angle.
Then cut (4) pieces of trim item C.
All the dimensions for the trim are longer than the final size because they will need to be individually cut to fit.
Gable end trim
Nail 1 piece of trim A and B to each of the gable ends starting at the top center.
They will overhang quite a bit but you will trim them to fit later. Nail with galvanized nails every 6 inches.
Take a piece of trim C and hold it firm to the bottom of the OSB and to the front gable trim piece. Mark the bottom and cut to length. Then nail the top 6 inches in place.
Take a piece of the front angle trim A or B and hold it in place flush to the edge of trim C and tight up to the gable end trim. Mark the bottom and cut to length. Hold in place and nail the top 6 inches.
Now line the corner edges of the two trim pieces up and nail from the top to the bottom being careful with the edge alignment.
Repeat for all corners.
Trim gable end pieces
Step 10: Shingle The Roof
Installing shingles on the roof of your shed might seem complicated but it’s easy if you take it one step at a time.
Use 3/4 inch long galvanized roofing nails for all the roof work.
Eave drip edge
Gable end drip edge
The glue strip on this starter row will hold the tabs of the next row of shingles in place.
Alternate rows with half tab removed
Begin the starter row with a full shingle, then cut half a tab off every other row of shingles.
This way every joints where the shingles come together will be covered by a full tab above it.
Put 4 roofing nails in each shingle about 5/8 inch above the tab cutout but below of the glue line.
Stack some supplies
Start the shingles from the front of the shed and work to the back because the starting edge will be neater and less ragged than the edge you cut to fit.
Work from the same end on both rows. This way you can use the cut offs from one side to finish the row on the other side.
Use the cutoffs from the other side of the shed if they are long enough.
Keeping your rows straight
Don’t wait till you get all the way to the top to find that your rows are uneven. If you can’t do it by eye then snap a chalk line.
You can also use the lines on the felt paper if you installed it square. But most likely you will need to snap a chalk line.
Cut ridge cap
The back edge of each tab tapers in so that it will fit neatly under the tab on top of it.
Nail ridge caps
Storage Shed Maintenance
Congratulations! You’ve just built a storage shed and saved a ton of money at the same time.
Now you need to protect your investment for the long term.
The first thing you need to do is to paint your new shed. Paint serves 2 functions. The first is to make your shed look good. The second and most important is to protect your shed. Paint is a barrier against the elements that keeps water and the sun from damaging the wood. It is a protective coating.
Caulking covers the large gaps that paint can’t cover. Then you paint the caulk to protect it too.
So give your new shed 2 coats of the best paint you can find. The better the paint the longer it will last which means time and money saved on repainting in the years ahead.
A good quality paint will last 5 to 10 years. Keep a close eye on it as it gets older and re caulk and re paint when necessary.
Whether done intentionally or accidentally, when termites find a path into the un treated wood of your shed they will make themselves at home and do damage to the wood long before you ever notice their presence.
Protect your shed from termites by keeping any dead plants away from your shed. Termites will eat the dead plants and find their way into the shed. Also avoid leaning untreated wood against the outside of your shed for the same reason. If you decide you need a ramp, then make it from pressure treated wood. I will not rot and is resistant to termites.
Your shed is put together with nails, screws and carriage bolts. But over time the wood these fasteners are installed into will relax and the fasteners will loosen up.
After your shed is 3 to 6 months old, walk around it with a hammer and inspect for nails heads that are popping up. This mostly happens in the floor. Just pound them back in. If it happens on the outside, re touch the paint around the area that the nail head broke through.
If the fasteners holding your door come lose, your door will start sagging. So be pro active here and keep the screws or bolts tight so your door stays in proper align.
Replace any loose or missing shingles immediately. Check the inside of your shed regularly for stains that indicate water damage. If you find some stains inside your shed, that is a sign that your roof has a leak.
Once you have found the leak, how you repair it will depend on where it’s located. Usually replacing any missing shingles and the proper application of a good quality caulk or roof coating will do the job.
After awhile you might notice your door latch doesn’t line up properly and you have to struggle to close the door. Your first thought is that the door is sagging. But in fact the shed has settled and is throwing the door out of align.
If and when this happens then jack up one corner of the shed until the door comes back in line and re block your shed. You might have to do this once or twice over time until the shed is completely settled.

Features Of These Sheds
The biggest difference between these shed plans is the roof line. All sheds can be built with roof trusses and wall studs 16 or 24 inch O.C. and floor joists 12 or 16 inch O.C. and use 2 to 5 skids in the foundation. All of the sheds can be built taller or shorter and doors installed anywhere you like.
These are the most versatile plans because they offer so many size and height options.
And it has a low profile with no complicated trusses to build.
This is one of the easiest sheds to build because it uses a simple truss design and small but easy to build overhang options.
These sheds look great!
And the higher roof pitches offer additional overhead storage in an easy to build loft area.
The barn style shed is very tall and might block yours or your neighbors views.
However if you can manage the barn style shed looks great and provides lots of additional storage if you build the optional loft.

Which Plans Should You Buy For Your New Shed Project?
Are you thinking about buying some shed plans but are confused and don’t know which ones to buy?
I will explain the similarities and difference between my 4 shed plans to help you in deciding which one is best for your new shed project.
The Main Differences Between These Plans Are
The most obvious difference in these plans is the roof lines. 2 of the plans are gable style roof, 1 is barn style or gambrel roof line and one is the single slope, lean-to style or flat roof.
The regular gable shed plans have 3 roof pitch options; 3:12, 4:12 and 5:12. The deluxe shed plans also have 3 roof pitch options of 3:12, 6:12 and 12:12. So the deluxe plans are good if you need a steep pitch for snow or leave fall off.
The barn roof pitch is fixed for the upper and lower half of the roof. The lean style roof is fixed at 1.5:12. So it’s good in low clearance situations or where the overall heigh is an issue.
All the shed plans except the lean to style use shingles on the roof. The advantage of shingles is that they’re relatively easy to install, economical and come in a wide variety of colors and textures and have a lifespan of up to 30 years. And you can easily match the roof on your home if necessary.
The lean to style sheds have too shallow of a roof pitch for shingles so they use either rolled mineral roofing or metal. Metal is a little more expensive but it’s fast and easy to install and has a life span of 50+ years.
There are 2 types of eave overhangs available in these plans. The simple 2-6 inch overhang and the full 12+ inch overhang. The 2 inch overhang is just the trim and a small overhang on the OSB. The 4 to 6 inch version is a 2×4 or 2×6 turned on edge.
The regular gable roof plans only offer the simple 2-6 inch overhang but the lean to and barn plans can be build with the either the 2-6 inch overhang or a full 12 inch overhang. The deluxe shed plans only offer the full 12 inch overhang.
With the regular gable and the lean to style plans the longest shed you can build is 20 ft. This is because they use a single top plate and 20 feet is the longest 2×4 you can buy. And with the single top plate it can’t be spliced to make longer. If you want a shed thats over 20 ft long then you can use either the tall barn style plans or the deluxe plans. Both of these can go up to 32 ft in length. But you can make it as long as you like.
The gable roof and lean to style plans are limited to 12 ft in width because they use a simple truss or rafter design. If you want to build over 12 ft wide then the tall barn and deluxe plans go up to 16 ft in width because they use a stronger but more complicated truss design.
Degree Of Difficulty To Build
The regular gable roof shed plans are the easiest and most economical to build because the walls are symmetrical and there are no complicated trusses to build or fancy overhang options. Trusses and overhang can are very time consuming in the shed building process.
The lean to sheds aren’t symmetrical but the rafters are strait without any cut outs and you can build it with either the simple 2-6 inch overhang or the more complicated full 12+ inch overhang.
Barn style trusses are easy to build but the added difficulty is working on the roof because of the increased pitch and greater overall working height. But you can build it with either overhang option.
The Deluxe shed is the most difficult to build because it doesn’t offer the simple overhang option, only the full 12 inch overhang. And the the trusses are more complicated because of the increased pitch and the 14 and 16 ft width options. And like the tall barn style shed, working on the deluxe roof is more difficult because of the steeper pitch and greater overall working height.
What They Have In Common
Now lets talk about what the plans have in common.
All of the sheds can be built on either a wood floor or concrete slab. For wood floors I have recommend 2×4’s at 16 inch on center for floors up to 8 ft wide, and 2×6’s 16 inch on center for floor over 8 ft wide. But you can make a stronger floor by using 12 inch centers and or 2×8’s floor joists.
Wall Stud And Truss Spacing
I recommend 2×4’s at 16 inch on center in the walls but you can use 24 inch centers for smaller sheds. I recommend trusses and rafters to be placed at 24 inch on center for sheds up to 12 ft wide, and 16 inch centers for sheds over 12 ft wide.
All sheds include instructions to frame for prehung doors and windows, or to build your own single or double door in any width or height and in any location, or build multiple doors.
All plans include instructions to build a ramp.
Estimate Cost To Build
All plans come with a materials list so you can calculate the cost to build it before you make that final commitment and start buying materials.
All plans are available in PDF format by instant download. When you click on the buy-now link you’ll be taken to a payment page. After paying you will almost instantly receive a download link in the email address associated with your paypal account or your credit card.
How Does The Download Process Work?
Sometimes your email and your browsers will not work properly together so you will have to cut the link from the email and paste it into a browser. That solves most of the issues.
But remember where you download the plans otherwise you will not be able to find them on your computer when you need them. Most people use the default download folder.
