8×12 Barn Shed Plans

This step by step diy project is about 8×12 barn shed plans. I have designed this barn shed so you can store tools, furniture and other items. However, the barn design allows you to create a loft for even more utilization of space. The double doors allow you to have an easy access to the interior of the shed. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

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. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

How to build a 8×12 barn shed

floor-frame

The first step of the project is to build the floor frame. Cut all the joists from 2×6 lumber and then lay them on a level surface. Make sure you place the joists every 16″ on center, for a professional result. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular joists. Align the edges flush.

Fitting the skids

Select the location for the shed and then level it properly. Compact a layer of gravel to the location and the lay the 4×4 skids. Fit the floor frame to the skids and then use rafter ties to connect them tightly, or just toe nail the frame to the skids.

Floor frame

Attach the 3/4″ plywood sheets to the floor frame. Align the edges flush and leave no gaps between the sheets. Drill pilot holes and insert 1 5/8″ screws, every 8″ along the joists.

Front-wall-frame

Continue the project by framing the front wall of the shed. Cut the plates and the studs from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Assemble the side walls for the barn shed on a level surface (I recommend you the floor of the shed). Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center.

Back-wall-frame

Assemble the back wall for the shed, using the techniques described above.

Assembling the shed frame

Fit the wall frames to the floor of the shed. Align the edges flush, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Moreover, you need to lock the adjacent walls together with 2 1/2″ screws. Plumb the wall frames and make sure the corners are square.

Side wall – Siding

Fit T1-11 siding to the sides of the barn shed. Align the edges with attention and leave no gaps between the sheets. Use 6-8d nails to secure the sheets to the framing.

Front wall – Siding

Cut the siding sheets as shown in the diagram and then secure them to the front of the shed. As you can see in the diagram, you need to inset the sheets 1 1/2″ from the top plate.

Back wall – Siding

Fit the siding sheets to the back of the 8×12 barn shed, in the same manner described above. Leave no gaps between the sheets and then insert them 1 1/2″ from the top plate.
