This step by step diy project is about 12×14 lean to shed shed plans. Today I share free plans for building the 12×14 lean to shed. This shed is compact and it comes with double front doors. Check out PART 2 and PART 3 or the project so you learn how to build the roof and the double doors. Make sure you comply with the local codes before staring the project. 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 12×14 lean to shed

Building-the-floor-frame
First of all, you need to build the floor frame for the 12×14 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. Select the location for the shed and remove the vegetation layer. Level the surface thoroughly.

Fitting the 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″.

Side-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.

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.

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.

Assembling the shed frame
After assembling the 4 wall frames, you need to lift them from the ground and fit them to the shed floor. Align the edges flush, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together tightly with 2 1/2″ screws. Make sure the corners are square and plumb the walls with a spirit level.

Top back wall frame
Build the top frame for the back wall from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center.

Fitting the top back wall
Fit the frame to the top of the back wall. Align the edges with attention, drill pilot holes through the bottom plate and insert 3 1/2″ screws into the frame.

Back wall 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.

Side wall panels
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.

For the life of me I cannot see how I am supposed to cut the 12 pieces of 48″x96″ in the way described. I really think it should be 13 pieces. Please let me know if I am wrong.
This is carpentry, not plastic surgery. If you need to buy another piece, buy another piece. Don’t get stuck with the project because of that.
