12×12 Run in Shed Plans

This step by step diy project is about free 12×12 run in shed plans. I have designed this run in shed so you can store tools, equipment or even garden furniture, having an easy access to the interior. Read the local codes before starting the project, so you comply with the legal requirements. 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 12×12 run in shed

Building the skids

The first step of the project is to build the beams for the base of the shed using 4×4 lumber. Cut both ends of the beams, as shown in the diagram. Make parallel cuts to the indicated areas and then remove the excess with a chisel. Smooth the surface with sandpaper.

Assembling the shed base

Select the location for the shed and then remove the vegetation layer. Level the surface with a spirit level and then fit the 4×4 pressure treated beams into place. Assemble the base for the shed using 3 1/2″ screws. Make sure the corners are square, drill pilot holes and then insert the screws to lock the base beams together tightly.

You can use 2×3 stake anchors to lock the base into the ground, every 16″. Alternatively, use hurricane anchors if you live an area with strong winds.

Back-wall-frame

The next step of the project is to build the back wall from 2×4 lumber. Cut all the components at the right dimensions, after taking accurate measurements. Make sure the edges are flush and check if the corners are square. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place double studs at both ends of the wall, with 1/2″ plywood between them. Fit the studs every 16″ on center.

Side-wall-frame

Build the side walls for the run in shed. Cut the components at the right dimensions and then assemble the frames using the same techniques described above.

Assembling the shed frame

Attach the walls to the base with 3 1/2″ screws. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the base beams. Use a spirit level to plumb the posts vertically and then check if the corners are square. Align everything with attention for a professional result. Secure the adjacent walls together tightly with 3 1/2″ screws. Leave no gaps between the walls and make sure the corners are square.

Posts

Use 2×8 lumber for the top beam. Use a circular saw to make parallel cuts inside the marked areas and then remove the excess with a hammer. Clean the recess with a chisel.

Top beam support

Fit the posts to the front of the shed. Plumb the posts with a spirit level and then make sure the corners are square. Use 4 1/2″ lag screws to secure the posts to the side wall frames. Drill pilot holes and insert the screws from the inside into the posts.

Fit the 2×8 beam to the top of the posts. Align the edges at both ends of the beam and then clamp it to the posts tightly. Drill pilot holes through the beam and posts and then insert 4″ lag screws. Use 3 bolts for each joint.

Front beam supports

Fit the rest of the posts to the front of the shed. Plumb the posts with a spirit level and then secure them to the top beam and to the base with screws.

Front-wall-supports—12×12-run-in-shed

Use 4×4 lumber for the braces and make 45 degrees at both ends. Fit the braces to the front wall and then secure them into place with 4 1/2″ screws. Drill pilot holes before inserting the screws to prevent the wood from splitting.

Front wall siding panels

Fit the T1-11 siding sheets to the front of the shed, as shown in the plans. Cut the sheets at the right dimensions and then attach them to the framing with 6d nails, every 8″ along the studs and plates.

Fitting the back wall siding panels

Fit the 5/8″ siding sheets to the back of the shed. Align the edges with attention and leave no gaps between them for a professional result. Use 6d nails, every 8″ along the framing, to secure the sheets into place tightly.
