12x8 Shed - Free DIY Plans | HowToSpecialist - How to Build, Step by Step DIY Plans

This step by step woodworking project is about free 12×8 outdoor shed plans. I have designed this relatively small shed so you can store all your garden tools in a professional manner. The storage shed features double front doors and a gable shaped roof. Remember that you need to read the local building codes before selecting the right location for the shed and before building the shed. See my other DIY projects 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. See all my Premium Plans HERE.

How to build a 12×8 gable shed

Building the floor frame

The first step of the project is to build the floor frame. Cut the joists from 2×6 lumber at the right dimensions 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. Place the joists every 24″ on center.

Fitting the skids

Fit 4×4 skids under the floor frame so you can lift the shed from the ground and keep it protected from moisture. Use rafter ties to lock the skids to the floor frame.

Fitting the floor sheets

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

Building the side walls

Build the side wall frames from 2×4 lumber. Drill pilot through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center. Place double studs to both ends of the walls and make sure the corners are square.

Front wall frame

Build the front wall from 2×4 lumber. Cut the plates and the studs at the right dimensions and then lay them on a level surface. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs and make sure the corners are square. 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.

Back wall frame

Build the back wall for the shed in the same manner described above. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center.

Assembling the shed frame

Fit the wall frames to the floor of the shed. Align the edges flush and plumb the walls vertically. Make sure the corners are square before locking the adjacent walls together tightly with 2 1/2″ screws. Drill pilot holes through bottom plates and insert 3 1/2″ screws into the floor.

Attaching the siding sheets

Side siding panels

Fit the T1-11 siding panels to the sides 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.

Front wall panels

Use T1-11 siding for the front of the shed. Make the cuts so you can fit the panels around the door opening.

Back wall siding

Fit the siding panels to the back wall of the shed. Align the edges flush and make sure you leave no gaps between the components, for a professional result.
