The 10 Steps

Construction is broken down into the following 10 steps which are common to all of my shed plans…
1) Foundation
2) Floor
3) Trusses
4) Walls
5) Door
6) Raise walls
7) Open door
8) Roof structure
9) Trim
10) Shingle roof

I decided to put all 10 steps in the same article so it will flow better and maybe be easier to go back and forth between the steps.

This site will show you how 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.

Tools

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.

Hand tools

  • Claw hammer
  • Tape measure and pencil
  • Speed square
  • Level
  • Chaulk line
  • Tin snips
  • Step ladder
  • Utility knife
  • Hand saw

Power tools

  • 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

Paint Equipment

  • Caulk gun
  • Brush
  • Roller and cage (or spray gun)

Disclaimers

Now before we get started with the actual building I have a couple of disclaimers…

Building Permits

You might need building permits to build a shed in your area so check with your local building department before you get started.

Building codes

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.

No guarantees

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

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 woodPressure treated means that the skids are rated for long term ground contact and are resistant to water rot and termite damage.

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.

concrete blocks under pressure treated skidsIf your site is not level then place concrete blocks under each skid every 4 feet or less and build the low points up with more blocks and wedges until the skids are approximately level.
how to level your shedDig the ground out to provide a stable base for the blocks or skids where necessary.

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.

gravel shed foundationIf drainage is a problem you can dig a trench under each skid about 12 inches wide and 12 inches longer than the length of your shed, fill it with gravel and place your skids on top.

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…

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.

Dig Holes

pier-foundationLay your skids out, level and square them as above. But don’t put a support block at the end of the skids where you will place the piers. Mark the ground where you will dig your holes about 6 to 8 inches from the end of the skids.

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.

Install Piers

pier-shed-foundationPlace the 4×4 piers into their holes and secure them to the skids. You can use a metal mending plate on each side, or a metal strap going over the top of the skid attached to either side of the 4×4 pier. Or you can use a specializes metal Simpson tie if they are avaliable in your local store.

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.

Finished Foundation

wood-concrete-pier-foundationNow you have a solid foundation to build your floor on.

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

Layout perimeter

pressure treated shed floor frameLay out pressure treated 4×6’s to make a wooden perimeter frame the same size as the shed. Turn them so they are 6″ tall. Pull a tape measure diagonally across to make sure the frame is square.

This is an example of a foundation frame for a 12×16 shed.

Install post and piers

complete concrete pier postMark where you want your post and piers to be. Remove the pressure treated wood perimeter frame and install the piers every 4 to 6 ft, as described previously.

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.

Attach shed

concrete pier post cutawayAttach the shed walls to this perimeter frame with 3 inch nails or screws through the bottom plate and galvanized 8d nails every 8 inches through the siding overhang.

This graphic shows a 5 1/2 inch tall frame with 1 inch siding overhang and 4 inch gap from ground level.

Got animals?

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.

stem-wall-completeThis can be a footer with a concrete block stem wall or a mono pour with the footer and stem wall made at the same time.

Build the outside of the stem wall the same size as your shed.

Attach with j-bolts

stem wall cross sectionAttach the shed walls to the stem wall with j-bolts embedded in the concrete 12 inches off each corner then 48 inches on center.

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.

Floor joist layout

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.

toe nail joist to skid

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 frame before sheeting

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.

blocks and wedges to level

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.

shed tie downs

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.

square and nail plywood

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.

shed floor blocking

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.

Snap a chalk line across the floor every 16 inches using the screw heads on the band boards as a guide.

Nail the center of your sheeting along the chalk lines every 8 inches.

toe nail rim joistsToe nail the front and rear rim joists to the skids. You have finished the floor.

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

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.

make a truss assembly jigMake a jig: Place two pencil marks eight feet apart on the edge of the unused 2×4 top plate.

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.

assemble the trussesAssemble trusses: Put the ends of two truss pieces into the jig and press everything together.

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.

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.

layout the wall studs

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.

spacer under truss collar beam

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 to 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.

square the siding and nail

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.

move a shed wall easily

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.

splice siding gable end wall

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.

Important:

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.

frame the sidewalls

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.

side wall stud spacer detail

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.

shed sidewall framing

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.

trim the lip

Snap a chalk line, then trim the ¾ inch lip overhanging the ends. There will be no overhang on 10 wide ends.

garden shed sidewall cut line

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 on top of the first

Build the second sidewall: Leave this finished wall in place and build the next wall directly on top of it.

Paint Now?

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.

Feedback

“Just wanted to compliment you on your plans and videos. I’m about half way thru and things are working out very well. Everything has been very straight forward. Would have been much harder without your plans and instruction. Thanks so much.”

“Thanks for your shed plans. I think I looked at every major plan outlet online and otherwise and I found your plans to be the most straightforward, easy to read and use, and easy to customize without fuss. I was worried with the name cheapsheds.com, but this shed I’m building from your plans is anything but cheap and I’m certain it will last the better part of the next 30 years. Great job on these plans.”

General notes:

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.
