6×12 Lean to Shed – Free DIY Plans

This step by step diy woodworking project is about 6×12 lean to shed plans. This small garden shed features a front door and double side doors, so you can have an easy access to the inside. This shed has a lean to roof, so you can build it next to the property line. Remember that you need to read the local building codes before starting the construction, so you comply with the legal requirements. See my other shed plans 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 HERE.

How to build a 6×12 lean to shed

Building the floor frame

The first step of the project is to build the frame for the lean to shed. As you can easily notice in the diagram, you need to cut the components at the right dimensions. Use a saw to cut the components from 2×6 lumber. Align the edges with attention and make sure the corners are square. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Place the joists every 16″ on center for a professional result.

Fitting the skids

Fit the 4×4 skids under the floor frame. Align the skids with attention and use screws to lock the frame to the skids. The skids will lift the frame from the ground and therefore, they will protect it from moisture.

Fitting the floor sheets

Fit 3/4″ plywood sheets to the floor frame. Align the edges flush and insert 1 5/8″ screws, every 8″ along the frame. Leave no gaps between the components.

Side wall frame

Building the wall frame for the tall side wall is a straight forward process, as you need to cut all the components at the right dimensions (2×4 lumber) and then lock them together tightly with 3 1/2″ screws. Place the studs every 24″ on center and check if the corners are square. Place double studs at both ends of the components for a professional result (fit a piece of 1/2″ plywood between the studs).

Side wall with double doors frame

Assembling the opposite side wall is also a straight forward job, but you need to frame a double door for a easy access inside. You can adjust the size of the double door to suit your needs. Use 2×6 lumber and 1/2″ plywood for the header.

Front wall frame

Next, you need to build the front wall frame. Cut all the components from 2×4 lumber, as shown in the diagram. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Use 2×6 lumber and 1/2″ plywood for the header. Make sure the corners are square and align the edges with attention. You can adjust the size of the door opening to suit your needs.

Back wall frame

Next, build the back wall for the lean to shed. Cut the components at the dimensions shown in the diagram and then use the same techniques described above to assemble the wall together tightly.

Assembling the shed frame

Fit the wall frames to the floor of the shed. Align the edges with attention and plumb the wall frames with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws. In addition, you need to lock the adjacent wall together tightly. Make sure the corners are square and align the edges with attention.

Top side wall frame

Build the top side wall for the lean to shed from 2×4 lumber. Cut all 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. Make sure the corners are square and align the edges with attention.

Fitting the top side wall

Fit the frame to the top of the plain side wall. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws to lock them together tightly.

Front wall siding sheets

Fit the T1-11 siding panels to the front of the shed. Align the edges with attention and leave no gaps between the sheets. Make cuts so you can fit the panels around the door opening. Insert 6-8d nails every 8″ along the framing.

Back wall siding sheets

Fit the siding sheets to the back of the small garden shed, making sure you leave no gaps between them.

Tall side wall siding sheets

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

Short side wall siding sheets

Fit the T1-11 siding sheets to the opposite side of the 6×12 garden shed. Align the edges with attention and insert 6-8d nails, every 8″ along the framing.

12×6 Lean to Shed Plans

This shed is sturdy and it is super easy to build, even if you don’t have a lot of framing experience. You can store almost anything inside this shed, due to the generous doors. The only constraint is the relatively small size of the shed, but otherwise the project is very versatile.

12×6 Lean to Shed Plans – Back view

This is a narrow shed, making it ideal for a small backyard. The front and side doors add unique appeal to the design and make it super easy to use. Don’t forget to take a look over PART 2 and PART 3 of the project so you learn how to build the roof and the front door for the storage shed.
