This step by step diy project is about 10×12 lean to shed shed plans. I had a lot of requests for this shed shape and size, so this is my go for it. This garden shed features double front doors and a lean to roof. This is the ideal shed project to build next to the property line or if you want a straight forward job. 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. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build a 10×12 lean to shed
First, build the floor frame for the 10×12 lean to shed. Cut the joists from 2×6 lumber. Lay the joists on a level surface and drill pilot holes through the rim joists. Place the joists every 16″ on center and then insert 3 1/2″ screws to lock them together tightly. Measure the diagonals and make adjustments till they are equal.
Choose the location for the lean to shed. Level the surface and then compact a layer of gravel. Use 4×4 lumber for the skids. Align the edges flush and toenail the frame to the skids. You can use 6×6 skids as well, if you want to lift the frame a little more from the ground.
Use 3/4″ plywood for the shed floor. Fit the sheets to floor frame and then secure them into place. 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.
Build the side walls for the shed 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, for a professional result. Align the edges flush and make sure the corners are square.
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 back wall of the shed. Cut the components 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.
Fit the wall frames to the floor of the shed. Align the edges flush and plumb the walls with attention using a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Moreover, you need to lock the adjacent walls together tightly with screws.
Fit the T1-11 siding sheets to the back of the shed. Align the sheets to the top plate and then insert 6-8d nails every 8″ along the framing so you can lock them into place tightly. Leave no gaps between the sheets for a professional result.
You need to take a look over PART 2 of the project, so you see how to frame the roof for the shed. In PART 3 of the project I show you how to build the double doors and how to fit the decorative trims.
I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project. See all my shed projects HERE.
