12×8 8×8 Gable Shed Plans

This step by step diy project is about 12×8 8×8 gable shed plans. I have designed this double shed so you can add unique appeal to your backyard. While this garden shed has a complex design, it will be super easy to build with my free plans and step by step instructions. 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. See all my Premium Plans HERE.

How to build a 12×8 8×8 gable shed

Small-shed-floor-frame

The first step of the project is to build the floor frame for the small shed. Cut the components for the floor from 2×6 lumber. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Make sure the corners are square and align the edges with attention.

Small shed skids

Select the location for the shed and level the surface thoroughly. Remove the vegetation layer and then level the surface, before laying the 4×4 skids, equally spaced. Fit the floor frame to the skids and then use 3 1/2″ screws to lock them together tightly.

Large shed floor frame

Continue the project by assembling the floor frame for the large shed. Cut the joists from 2×6 lumber, as shown in the diagram. Drill pilot holes through the rim joists and then insert 3 1/2″ screws into the perpendicular joists. Place the joists every 16″ on center, making sure the corners are square.

Large shed skids

Fit the 4×4 skids under the floor frame, as shown in the diagram. Use screws or rafter ties to lock the skids to the floor frame, in a professional manner.

Assembling the floor frame

The next step of the project is to join the two frames together tightly. Align the edges with attention and use 3 1/2″ screws to lock them together tightly. Make sure the top surface is perfectly horizontal.

‘ Floor sheets

Fit the 3/4″ plywood sheets to the floor frame of the shed. Use the pattern shown in the diagram and leave no gaps between the sheets. Insert 1 5/8″ screws, every 8″ along the framing.

Building the wall frames

Small-shed-front-wall

The next step of the project is to build front wall for the small shed. Use 2×4 lumber for the plates and for the studs. Use 2×6 lumber and 1/2″ plywood for the double door header. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs and then build the door opening.

Small-shed-side-wall

Continue the project by assembling the small shed side wall. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Use 2×6 lumber and 1/2″ plywood for the double header. Place the studs every 16″ on center.

Back wall frame

Next, build the back wall frame. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center. Make sure the corners are square.

Large-shed-side-wall-with-door

Build the side wall with double doors for the large shed, using 2×4 lumber. Use 2×6 lumber and 1/2′ plywood for the double header. You can adjust the size of the door opening to suit your needs.

Large-shed-front-wall

Build the front wall for the large shed. As you can see in the diagram, you need to frame a 32″x32″ window. Use two pieces of 2×6 lumber and one piece of 1/2″ plywood for the double header.

Large shed side wall

Use 2×4 lumber for the studs and plates. Assemble the side wall for the large shed using the same techniques described above.

Building the shed frame

Fit the wall frames to the floor frame of the shed. Align the edges with attention, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Plumb the walls with a spirit level and then lock the adjacent walls tightly with 3 1/2″ screws.

Fitting the side panels

Back wall siding sheets

Fit the T1-11 siding sheets to the back wall of the shed. Align the sheets to the top edge of the wall. Leave no gaps between the sheets and then insert 2″ nails, every 8″ along the framing.

Side wall with doors siding panels

Fit the T1-11 siding sheets to the side wall of the large shed. As you can see in the diagram, you need to make a few cuts so you can fit the sheets around the door opening.

Front wall siding panels

Fit the siding sheets to the front of the shed. Make the cuts so you can fit the sheets around the door and window openings. Use 2″ nails, every 8″ along the framing.

Side wall siding panels

Fit the rest of the siding sheets to the shed. Make cuts to the sheets, so you can fit them around the window opening.
