How to Build Small Hay Shed

Updated July 20, 2017

Building a small 6-foot by 8-foot shed for storing hay is a fairly simple process, but it does require some time and physical labour. It can also save you money doing it yourself rather than buying one at a store. All that is required to build one on level ground are a few basic tools, four types of lumber and hardware.

Trim four 8-foot 2-by-12s down to 5-foot 9-inches and leave three at 8-foot. Six pieces are for the base of your shed and one is to create the roof slope.

Construct the outer frame for the shed on the levelled area using four 2-by-12s. Lay the two 8-foot pieces on edge parallel to each other 6-foot apart and insert a 5-foot 9-inch piece between them on each side, forming a rectangle. Nail them together.

Add floor support inside the frame. Equally space the other two 5-foot 9-inch 2-by-12s inside the frame between the other 5-foot 9-inch pieces. Nail them to the 8-foot sides of the outer frame.

Align 21 8-foot 2-by-4s over the frame side-by-side perpendicular to the support beams for the floor of your shed. Drive nails down through each 2-by-4 board where it touches the frame and support beams.

Plan for a 3-foot wide by 6-foot-high opening in one wall frame for a door. Use two 2-by-4s side by side on each side and on the top of the door.

Assemble the two 8-foot-long by 7-foot-high wall frames. Use two 8-foot and two 6-foot 9-inch 2-by-4s for each frame. Next, insert 6-foot 9-inch vertical studs between the 8-foot pieces and space them 8 inches apart.

Assemble the two 6-foot wall frames. Each frame is 5-foot 5-inches-long because they fit between the other two 8-foot frames. Use two 5-foot 5-inch pieces of 2-by-4 for the top and bottom of each wall and two 6-foot 9-inch pieces for the sides and the studs.

Stand all four walls up around the edges of the floor and nail them together. Nail each wall to the floor every 6 inches along the bottom. Also nail them to each other every 4 inches from top to bottom.

Nail the remaining 8-foot 2-by-12 on edge along the top of one of the 8-foot wall frames for the slope of the roof.

Cut four 7-foot 2-by-4s for the roof support. Lay them from the top of the 8-foot frame up to the top of the 2-by-12 so they are equally spaced them out between the 6-foot sides. Nail them down.

Cut sheets of 1/2-inch plywood to cover the roof and nail them to the 2-by-4 roof supports.

Cut 1/2-inch plywood and cover the outside of all four walls. Nail to the studs.

Cut pieces of tin and attach to the roof for added protection.

Have doors made or cut your own using plywood. Hang your doors with heavy-duty hinges.


Be cautious when using power tools.
