12x12 Gambrel Shed Plans - Free DIY Download MyOutdoorPlans (2024)

This step by step diy project is about diy 12×12 gambrel shedplans. 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.

Remember that all my woodworking plans come with 3D diagrams, step by step instructions and a full Cut / Shopping list.

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.

It’s that easy to build your own 12×12 barn shed!

Step 1: How to build a 12×12 barn shed floor

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.

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.

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.

Step 2: Building the shed wall frames

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.

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.

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.

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

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.

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.

Step 3: Fitting the 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.

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.

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.

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.

This is a family friendly shed, as it is extremely versatile. You can use it for storing furniture, toys and other items, or you can use it as a small hobby workshop.
