5×20 Lean to Shed Plans – Free PDF Download

This step by step diy project is about 5×20 lean to shed plans. I have designed this small shed so you can store your garden tools and furniture with easy. If you have a narrow backyard, you can build this shed and save space. This shed features 8′ double front doors and a lean to roof. Please read the local codes before starting the project and make the necessary modifications to comply with the legal regulations. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. See all my Premium Plans HERE.

How to build a 5×20 lean to shed

Building a shed frame – 5×20

The first step of the project is to build the floor frame. Cut the components from 2×6 lumber, as shown in the diagram. Place the joists every 16″ on center, for a professional result. Check if the corners are are square, drill pilot holes through the rim joists and insert 3 1/2″ screws.

Fitting the skids under the shed frame – 5×20 shed

Select the location for the shed and level the surface thoroughly. Remove the vegetation layer and make sure you comply with the local building codes. Fit the skids on the location. Place the floor frame and then use rafter ties to lock the skids to the frame. Align the edges with attention for a professional result.

Fitting the floor sheets

Fit the 3/4″ plywood sheets to the floor frame and align the edges with attention. Insert 1 5/8″ screws every 8″ along the joists. Leave no gaps between the sheets for a professional result.

Back wall frame – 5×20 shed

Build the back walls of the shed from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Align the edges and make sure the corners are square. Alternatively, you could use framing nails and a framing gun.

Front wall frame – 5×20 shed

Continue the project by assembling the front wall frame. Use 2×4 lumber for the front wall frame. Use 2×6 lumber and 1/2″ plywood for the double header. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Make sure the corners are square and align the edges flush. You can adjust the size of the door opening to suit your needs.

Side wall frames – 5×20 shed

Build the side walls for the shed using the same techniques described above and the information from the diagram.

Assembling the shed frame – 5×20 shed

Fit the wall frames to the floor of the shed. Align the edges with attention and plumb the walls with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together tightly using 3 1/2″ screws.

Top back wall frame

Use 2×4 lumber for the top back wall frame. Cut the components at the right dimensions and then lay them on a level surface. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Fitting the top back wall frame

Place the wall to the top of the shed frame. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly.

Front wall siding sheets – 5×20 shed

Fit the sheets to the front of the shed. As you can see in the diagram, you need to make the cuts so you create the door opening. Use 6d nails every 8″ along the frame, to secure the sheets into place tightly.

Back wall siding sheets

Fit the T1-11 siding panels to the back of the shed. Align the edges with attention and leave no gaps between the sheets. Insert 6-8d nails every 8″ along the framing.
