6×12 Gable Shed – Free DIY Plans

This step by step diy woodworking project is about 6x12 storage shed plans. If you are looking for a narrow storage shed with a gable roof, you need to take a look over my latest design. This shed has a front door for easy access to the interior. 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.

How to build a 6×12 gable shed

Building the floor frame

Building the floor frame

The first step of the project is to build the floor frame of the shed. As you can easily notice in the diagram, you need to use 2×6 lumber for the joists. Take accurate measurements and then cut the components at the right dimensions. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular beams. Align the edges and make the corners are square.

Fitting the skids

Fitting the skids

Select the location for the storage shed and level the surface with attention. Lay the 4×4 skids on the ground and then fit the floor frame. Use rafter ties to lock the floor frame to the skids. Align everything with attention and insert the screws to lock the skids to the floor frame tightly.

Floor sheets

Floor sheets

Lay the 3/4″ plywood sheets to the floor frame. Align the edges with attention, drill pilot holes and insert 1 5/8″ screws. Insert the screws every 8″ along the 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. Place the studs equally spaced. Use 1/2″ plywood and 2×4 lumber for the double header. You can adjust the size of the door opening to suit your needs.

Side wall - frame

Side wall – frame

Building the side wall frames is a straight forward process, as you need to cut all the components at the right dimensions 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.

Back wall - frame

Building the back wall is easy, as well. 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

Lift the wall frames from the ground and it them to the floor of the shed. Start with the side walls. Plumb everything with a spirit level and then align the edges flush. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together with 2 1/2″ screws, after drilling pilot holes.

Front wall - siding

Front wall – siding

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.

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

Back wall siding

Back wall siding

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