10×20 Shed Plans – DIY Lean to Shed

This step by step woodworking project is about 10×20 lean to shed plans. If you need a large shed that can be built next to the property line, you should take a look over my design. This is a simple but sturdy shed, that features a basic lean to roof and double front doors. Read the local codes before starting the project, so you comply with the requirements. See my other DIY projects HERE.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. My plans come with a full cut / shopping list and they are PDF Download and Print friendly. See all my Premium Plans HERE.

10×20 Slanted Shed Roof – DIY Plans

10×20 Shed – Floor plans

The first step of the project is to build the floor frame. Cut the joists at from 2×6 lumber. Align the edges flush and make sure the corners are square. Place the joists every 16″ on center. Drill pilot holes and insert 3 1/2″ screws. Alternatively, you can use joist hangers.

Fitting the skids – 10×20 shed

Use 4×4 lumber for the skids. Place the skids under the floor frame. Use rafter ties to secure the skids to the floor frame.

Fitting the floor sheets – 10×20 shed

Use 3/4″ tongue and groove plywood sheets. Cut the sheets at the dimensions shown in the diagram and in the cut list. Leave no gaps between the sheets and align the edges flush. Drill pilot holes and insert 1 5/8″ screws every 8″ along the framing, to secure the sheets into place.

Building the side walls – 10×20 shed

Use 2×4 lumber for the side wall frame. Cut the components at the right dimensions, as shown in the diagram. Drill pilot holes through the plates and insert 3 1/2″ screws to assemble the wall frame. Make sure the corners are square and align the edges flush. Place the studs every 16″ on center. You can add windows to the frames, if you want to have natural light inside the storage shed.

Front wall frame – 10×20 shed

Next, assemble the front wall frame. Use 2×4 lumber for the components. Use 2×6 lumber for the double door header. You can adjust the size of the door to suit your needs.

Back wall frame – 10×20 shed

Build the back wall using the same techniques described above. Place the studs every 16″ on center. Use double studs at both ends of the frame.

Assembling the shed frame – 10×20 lean to

Fit the wall frames to the floor of the shed. Align the edges flush and plumb them vertically with a spirit level. Drill pilot holes and insert 3 1/2″ screws through the bottom plates into the floor frame. Check if the corners are square and lock the adjacent wall together tightly with 3 1/2″ screws.

Next, build the wall frame for the back of the shed. Alternatively, you can place this frame to the front of the shed, if you want a roof with a backward slope.

Fitting the top back wall – 10×20 shed plans

Fit the frame to the front of the shed and align the edges flush. Drill pilot holes through the bottom plate of the top frame and insert 3 1/2″ screws. Plumb the top wall with a spirit level.

Front panels – 10×20 shed

Use 5/8″ T1-11 siding sheets for the front wall. Attach the siding sheets to the front wall and align the edges flush. Insert 8d nails along the wall frames, every 8″. Use a saw to cut out the openings for the door.

Attach the siding sheets to the back of shed, as well. Leave no gaps between the sheets and align the edges flush.
