This step by step diy project is about 8×12 lean to shed plans. I have designed this 8×12 lean to shed so you can store many items in a stylish manner. The shed has a nice design and wide double front doors so you can access the interior easily. You can even store your lawn tractor in the shed. Read the local building codes to understand what are the requirements you need to comply with. 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. See all my Premium Plans HERE.

Building a 8×12 lean to shed
The first step of the project is to assemble the floor frame using 2×6 lumber. Cut the joists at the right dimensions and lock them together with 3 1/2″ screws. Drill pilot holes through the rim joists and insert the screws into the perpendicular components. Align the edges flush and check if the corners are square.
The nest step of the project is to attach the 4×4 skids to the frame of the shed. Align the beams at both ends, using the information in the diagram. Drill pilot holes and insert 4 1/2″ screws to secure the skids to the beams. Alternatively, you can use metal hardware to connect the components.
Attach 3/4 tongue and groove sheets to the floor frame. Align the edges flush, drill pilot holes and insert 1 5/8″ screws every 8″ along the joists.
The next step of the project is to build the front wall for the shed. Cut the components at the right dimensions, drill pilot holes through the plates and insert 2 1/2″ screws into the studs. Make sure the corners are square and align everything flush. As you can easily notice in the diagram, you need to double the ends studs and attach cripple studs for the door.
As you can see in the plans, you need to fit 1/2″ plywood fillings between the double end studs.
Build the double header for the door from 2×6 lumber and 1/2″ plywood. Align the edges with attention, add glue to the joints and insert nails to lock everything together tightly.
Next, build the back wall from 2×4 lumber. Drill pilot holes through the plates and insert 2 1/2″ screws into the studs. Make sure the corners are square and align the edges flush for a professional result. Toe-nail the horizontal supports to the frame of the shed, after aligning the edges flush and making sure the corners are square.
Fit the front and the back walls to the shed floor. Use a spirit level to plumb the walls, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor.
Build the side walls from 2×4 lumber, using the same techniques described above.
Fit the side walls to the floor of the shed and align the edges flush. In addition, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Make sure the corners are right-angled and lock the adjacent walls together by inserting drill pilot holes and inserting 2 1/2″ screws.
Attach T1-11 siding panels to the front of the lean to shed. In addition, cut out the door opening and secure the panels to the framing with 4d nails. Align the edges flush with the wall frames before inserting the nails.
Attach the T1-11 siding sheets to the back of the lean to shed. Leave no gaps between the sheets and secure them to the framing with 4d nails.
Make sure you take a look over PART 2 of the project, where I show you how to build the roof and how to make the double doors for the shed.
This is a simple project you should be able to build in a few days without much effort. This 8×12 lean to shed is ideal if you want to attach it to an already existing building on your property or if you want to build it next to the property line, for example.
