Draw a rudimentary sketch of your shed's exterior. You will use this to estimate the amount of lumber you will need to build your unit. Calculate two sidewalls if your shed will be placed next to your house in your backyard. Make it three if it is going to be freestanding.
Tamp down the ground and make sure that the land is as level as possible. Use rocks to cover the earth and provide an additional layer to elevate the woodpile from the ground. This is especially recommended for low properties that are prone to water intrusion or floods.
Use your stakes and strings to mark off the parameters of your shed floor area.
Frame up your walls to spec. Add the braces to the corners of your wall frame by screwing them in using a few screws and your screwdriver.
Secure the frames directly to your exterior wall if you are creating an attached shed. Use your nails and hammer to secure the frames. Frame up three sides on the shed's surface if you are creating a stand-alone, and lift them into place by nailing them to form a three-sided shed skeleton.
Nail the 2-by-4 planks of lumber horizontally and vertically to your wall frames to completely enclose the walls.
Construct your rafters by laying the 2-by-4 boards across the top of your wall frames. Cover the flat area of your roof with plywood.
Complete the shed exterior by sanding it with fine-grit sandpaper. Apply primer to the newly sanded exterior and leave it to dry for at least 5 hours before stocking the shed with plywood.
- You can use roofing shingles to cover the roof's plywood to keep it dry.
