12x12 Shed Plans | HowToSpecialist - How to Build, Step by Step DIY Plans (2024)

This step by step diy woodworking project is about 12×12 shed plans.I have designed this square shed with a gable roof so you can enhance the storage space in your backyard. If you want to organize all your tools and other items in your garden in a professional manner, this storage shed is a great option. Remember that you need to read the local building codes before starting the construction, so you comply with the legal requirements.

Fit the door inside the opening and lock it to the 1×4 jambs with metal hinges. After you check if the door opens properly, you should install the hinges, as well as a strong latch. Work with attention and with great attention, if you want to get the job done as a professional and to prevent costly mistakes. Last but not least, apply a few coats of exterior paint to enhance the look of the shed and to protect the components from decay. See HERE how to build double shed doors.

12×12 Shed Plans

The first step of the project is to build the floor frame for the shed. Therefore, you need to use 2×6 lumber for the joists and then lay them on a level surface. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Align the edges flush and make sure the corners are square. Place the joists every 16″ on center for a neat result.

Select the location for the shed and level it up with attention. Make sure you read the local building codes before selecting the location for the shed. Lay the skids on the ground and then fit the floor frame. Toenail the frame to the skids or you could use rafter ties to connect them together tightly. Make sure the corners of the floor frame are equal for a neat result.

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

Continue the project by assembling the side walls for the shed. As you can easily notice in the diagram, you need to cut the components from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center, for a neat result.

Remember that you can easily adjust the size of the walls to suit your needs.

Assemble the back wall for the shed, using the same techniques described above.

Framing the front wall is a straight forward process, if you follow the instructions from the diagram. You need to use 2×6 lumber for the double header. Therefore, cut the headers at 75″ and fit a piece of 1/2″ plywood. Insert 2 1/2″ screws so you can lock the double header together tightly. Toenail the double header to the studs. You can adjust the size of the door opening to suit your needs.

After assembling the wall frames, you need to lay them to the floor of the shed. Align the edges with attention and plumb them with a spirit level. Drill pilot holes through the bottom plate and insert 3 1/2″ screws into the floor. Moreover, you need to lock the adjacent walls together tightly by using screws. Make sure the corners are square.

Fit T1-11 siding to the back of the shed. Align the sheets to the top plates and then secure them to the framing with 6-8d nails, every 8″. Leave no gaps between the sheets for a professional result.

Fit the T1-11 siding sheets to the front of the shed, as well. As you can easily see in the 12×12 shed plans you have to make a few cuts so the panels fit around the door opening nicely.

Attach the siding sheets to the back of the shed, as well. Align the edges flush and insert the nails every 8″ along the framing.

This storage shed features large double doors placed to the front of the shed. Moreover, this shed is large enough for the needs of a homeowner. You need to take a look over PART 2 and PART 3 of the shed project, so you see how to build the gable roof and how to make the double doors.
