12×12 Gambrel Shed Plans – Free DIY Download

This step by step diy project is about diy 12×12 gambrel shed plans. This is a compact barn shed that you can build in less than one week, if you get some help from a friend. I personally like this shed very much, because you can choose between the double front doors and the smaller side door, to access the interior. In addition, it features a side window to let some light inside. Make sure you read the local building codes and make the needed adjustments to 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.

How to build a 12×12 barn shed

Floor frame - 12x12 shed plans

Floor frame – 12×12 shed plans

The first step of the project is to build the floor frame for the 12×12 barn shed. Cut the joists for the shed using 2×6 lumber. Align the edges flush on the selected location for the shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock the joists into place. Place the joists every 16″ on center for a professional result.

Fitting the skids

Fitting the skids

Select the location for the shed and remove the vegetation level. Lay gravel to the surface and then lay the 4×4 skids, below the floor frame. Use rafter ties to secure the skids to the frame. Align the edges with attention.

Floor sheets - 12x12 shed plans

Floor sheets – 12×12 shed plans

Use 3/4″ plywood sheets to the floor frame. Align the edges with attention, drill pilot holes and insert 15/8″ screws, every 8″ along the joists. Leave no gaps between the sheets for a professional result.

Front wall frame

Front wall frame

Continue the project by assembling the front wall frame for the shed. Cut the components from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. In addition, you need to build the double header from 2×6 lumber. Fit 1/2″ plywood between the double headers. Lock them together with glue and 2 1/2″ screws. Make sure the corners are square and align the edges. You can adjust the size of the door opening to suit your needs.

Back wall frame

Back wall frame

Continue the project by assembling the back wall for the shed. Cut all the components at the right dimensions. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center, for a professional result.

Plain side wall - 12x12 shed plans

Plain side wall – 12×12 shed plans

Build the plain side wall for the shed using the same technique described above. Place the studs every 16″ on center and align the edges flush.

Plywood blockings

Place 1/2″ plywood blockings between the double end studs.

Side wall with door frame - 12x12 Barn Shed

Side wall with door frame – 12×12 Barn Shed

Build the opposite side wall, as shown in the diagram. I recommend you to frame a side door and two small window. These small additions will let enough light inside the shed and an easy access, if you don’t handle large objects.

Assembling the shed frame - 12x12 barn

Assembling the shed frame – 12×12 barn

Fit the wall frames to the floor of the shed. Align the edges flush and plumb them with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor of the shed. Make sure the corners are square and lock the adjacent wall together with 3 1/2″ screws. Drill pilot holes before inserting the screws to prevent the wood from splitting.

Side wall siding sheets

Side wall siding sheets

Fit the T1-11 siding sheets to the side wall of the barn shed. Align the edges flush and insert 6d nails to lock the sheets into place tightly. Leave no gaps between the sheets for a professional result.

Side wall with door siding sheets

Side wall with door siding sheets

Fit the T1-11 siding sheets to the opposite side wall. Use a saw to make the cuts, so you can fit the panels around the window and door openings. Use 6d nails every 8″ along the framing to secure the sheets into place.

Front siding sheets

Front siding sheets

Fit the T1-11 siding sheets to the front of the wall. Cut the sheets using the information from the diagram, so you can lock them into place around the door opening. Use 6d nails to secure the panels into place, every 8″ along the framing.

Back wall siding sheets

Back wall siding sheets

Fit the T1-11 siding sheets to the back of the 10×12 barn shed. Inset the sheets 1 1/2″ from the top plates. Leave no gaps between the sheets and secure them into place with 6-8d nails, every 8″ along the framing.
