12×12 Lean to Shed Plans

This step by step diy project is about 12×12 lean to shed shed plans. This is a compact shed with a lean to roof with the slope towards the front. You can build this shed in one week, but make sure you read the local codes and make the necessary adjustments to comply with them. 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.

Building a 12×12 shed with a lean to roof

Building the floor frame

First of all, you need to build the floor frame for the 12×12 shed. Cut the joists from 2×6 lumber at the dimensions shown in the diagram. Lay the joists on a level surface and then align the edges flush. Make sure the corners are square and then drill pilot holes through the rim joists. Insert 3 1/2″ screws to lock the components together tightly.

Fitting the skids

Fit 4×4 skids under the floor frame. Place the skids equally spaced and then lock them to the frame with rafter ties.

Floor sheets

Fit the 3/4″ plywood sheets to the floor of the shed. Align the edges flush and leave no gaps between them. Insert 1 5/8″ screws to lock the sheets along the joists, every 8″.

Building the wall frames

Side-wall-frames

The next step of the project is to build the side wall frames from 2×4 lumber. 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. Check if the corners are square and place the studs every 24″ on center, as shown in the diagram.

Front-wall-frame

Frame the front wall using the information from the diagram. Cut the components from 2×4 lumber at the dimensions shown in the plans. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Use 2×6 lumber for the double header and fit 1/2″ plywood between the beams. Drill pilot holes and insert 2 1/2″ screws to assemble the double header. You can adjust the size of the door opening to suit your needs.

Back-wall-frame

Cut the components for the back wall from 2×4 lumber, after taking accurate measurements. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center, for a professional result. Make sure the corners are square and align the edges flush.

Fitting the wall frames

Fit the wall frames to the floor of the shed. Align the edges flush and plumb the walls with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws to lock them into place tightly. Moreover, you need to lock the adjacent walls together tightly using 2 1/2″ screws. Make sure the corners are square for a professional result.

Top-back-wall-frame

Build the top frame for the back wall, using 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.

Assembling the shed frame

Fit the wall frame into place with attention. Align the edges with attention, drill pilot holes through the bottom plate and insert 3 1/2″ screws to lock it into place tightly.

Fitting the siding sheets

Side wall siding sheets

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

Front wall siding sheets

Fit the T1-11 siding sheets to the front of the shed. Make the cuts so you can fit the sheets around the door opening. Insert 6-8d nails, every 8″ along the framing.

Back wall siding panels

Fit the panels to the back of the shed, as well. Leave no gaps between the sheets and align everything neatly. Insert 6-8d nails every 8″ along the framing.
