8×12 Lean to Shed Plans

This step by step woodworking project is about free 8×12 lean to shed plans. If you need more storage space in the backyard, but you are short on space, building this lean to shed will make the most of it. Check out PART 2 and PART 3 of the project, so you learn how to build the roof and the double doors. Read the local codes before starting the project, as in some cases a permit might be required. 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. See all my Premium Plans in the Shop.

Building a 8×12 lean to shed

Building-the-floor-of-the-shed

Build the floor for the garden shed from 2×4 or 2×6 lumber. Cut the joists at 144″ and at 93″ using a sharp saw. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Make sure the edges are flush. Measure the diagonals and make adjustments till they are equal.

Attaching-the-skids

Attach 4×4 skids to the floor frame, so you can lift the shed from the ground and protect it from moisture. Drill pilot holes through the joists and insert 4 1/2″ screws into the skids. Alternatively, you can use rafter ties to secure the skids to the floor frame.

Fitting-the-floor-sheets

Attach the 3/4″ plywood sheets to the floor frame. Align the edges flush, drill pilot holes and insert 1 5/8″ screws, every 8″ along the joists. Leave no gaps between the sheets for a professional result.

Front wall – Frame

Build the frame for the front wall from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. In addition, you need to use 2×6 lumber for the double header. Fit 1/2″ plywood between the double headers and insert 2 1/2″ screws to lock them together tightly.

Back wall – Frame

Continue the project by assembling the back wall frame. Cut all the components to the right dimensions, according to the information from the diagram. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center. Fit the middle supports between the studs, by toenailing them.

Side walls – Frames

Build the side wall frames using the same techniques described above. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Building the shed frame

Fit the wall frames to the floor of the shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws into the floor. In addition, lock the adjacent walls together by using screws, Use a spirit level to plumb the walls and a carpentry square to make sure the corners are right angled.

Back wall – Siding

Fit the T1-11 siding panels to the back wall of the shed. Align the edges with attention and insert 6-8d nails, every 8″, along the framing. Leave no gaps between the sheets for a professional result.

Side walls – Siding

Cut the panels to the right size, as shown in the diagram. Fit the T1-11 siding panels to the sides of the lean to shed. Align the edges with attention and insert 6-8d nails into the framing, every 8″ along the structure.

Front wall – Siding

Cut the panels for the front wall from T1-11 siding at the right dimensions. Attach the panels to the front wall using 6-8d nails.
