8×20 Gable Shed Plans

Ovidiu 0 FavoriteLoadingAdd to favorites List YOUR FAVORITES GapDice RANDOM PLAN

This step by step diy project is about 8×20 shed plans. If you need a significant storage space with an easy access through wide doors, this gable shed is perfect. In addition. I have designed this shed so you can keep the costs down. This shed features double doors on the front and a gable roof with a 5:12 pitch. Make sure you check the local codes and make adjustments to the plans, if required. 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 8×14 shed

Floor frame

Floor frame

The first step of the project is to build the floor frame. Cut the components from 2×6 lumber at the right dimensions. Place the joists every 16″ or 24″ on center, for a professional result. The 16″ spacing will allow you to store heavy items, while the 24″ spacing will help you save money. Check if the corners are are square, drill pilot holes through the rim joists and insert 3 1/2″ screws.

Fitting the skids

Fitting the skids

Select the location for the shed and level the surface thoroughly. Remove the vegetation layer and make sure the location complies with the local codes. Fit the skids on the location. Place the floor frame and then use rafter ties to lock the skids to the frame.

Fitting the floor sheets

Fitting the floor sheets

Fit the 3/4″ plywood sheets to the floor frame and align the edges with attention. Insert 1 5/8″ screws every 8″ along the joists. Leave no gaps between the sheets for a professional result.

Back wall frame

Back wall frame

Build the plain side wall of the shed from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Align the edges and make sure the corners are square.

Side wall with door frame

Side wall with door frame

Build the opposite side wall for the shed, using the information from the diagram. As you can see in the image, the wall has an opening for 8′ double doors. Use 2×6 lumber and 1/2″ plywood for the double header. Lock the double header into place with screws. Make sure the corners are square for a professional result.

Front wall frame

Front wall frame

Continue the project by assembling the front wall frame. Use 2×4 lumber for the front wall frame. Use 2×6 lumber for the double header. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Make sure the corners are square and align the edges flush. Build a double header for the door from 2×4 lumber and 1/2″ plywood. You can adjust the size of the door opening to suit your needs.

Back wall frame

Build the back wall for the shed using the same techniques described above and the information from the diagram.

Assembling the shed frame

Assembling the shed frame

Fit the wall frames to the floor of the shed. Align the edges with attention and plumb the walls with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together tightly using 3 1/2″ screws.

Side siding panels
