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.

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.

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.

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

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

Back wall siding sheets

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
