Now it’s time to attach the walls to the floor.
If you want to make this shed modular:
If you want to make this shed modular you will be able to disassemble it and move it in 6 large pieces… the floor and roof and 4 walls.
This might be handy if you want to get it through a small gate in the future.
At this point the single largest component will be 4 inches by 4 feet by 7 feet.
If you want to make it modular don’t use nails to assemble the shed from here on. Use 3 inch drywall screws to secure the studs to each other and use 2 inch drywall screws with a fender washer to secure the siding to the underlying stud.
If you don’t need it to be modular then skip this step and use nails to assemble the shed.
Assemble walls: Start with the back wall. Lift it in place and position it correctly side to side and push it up securely into the floor at the back. Then nail or screw the bottom plate to the floor.
Then lift a sidewall on the floor and bring it up flush to the back wall. When they are tight to each other nail through the sidewall corner stud into the back wall corner stud at the top and bottom. Then nail through the bottom plate at each corner into the floor.
Attach the next wall the same way. Lift the final wall into place. Since you can’t get inside at this point, put a nail through the siding into the underlying corner stud at the top and bottom corner of each side of the walls.
All 4 walls attached.
Make sure the siding fits tight at the edges before you nail anything together.
Router: Now you can router the excess off both sides. Start at the bottom and the router bit will follow the 2×4 frame up to the top, across the top and down the other side to the ground.
Now you can nail or screw the siding to the underlying corner studs.
Door: Remove the screws holding the door and open it for the first time.
Go inside and finish nailing or screwing the walls to each other and to the floor. I was anxious to test for fit so I put a bike in. It fits perfectly…
Latch: I used a simple gate latch like I do on all my sheds. You can find something more secure if you feel it is necessary.
Install latch: You could have installed the latch at the same time as the hinges.
If you install it now you will have to drill through the corner studs then go to the back side and cut through the sidewall corner stud to the front wall corner studs with the 1 1/2 inch spade bit to make access to the washers and nuts. The same way you needed to make access for the hinges.
Paint: This is an ideal time to paint because there will be nothing to cut in.
But first clean the metal parts to make sure the paint will stick. Use paint thinner and remove any oil from the hinges and latch.
You can paint right out of the can and it will go very quickly. Give it two coats of a high quality exterior paint.
Caulk: Paint in the door jambs too. If you have a gap like this simply fill it in with a good caulk and paint over after it dries.
If you have built your shed carefully to size then your corners will fit tightly and will not need trim.
