A storage shed in your yard makes good sense. It may even be a necessity if you don’t have a garage or if you have only a small, single-car garage. A simple shed with 2x4 stud walls and rafters is a relatively easy construction project for the above-average do-it-yourselfer. Starting from the ground up is a good way for a beginner to gain experience in carpentry. If you aren’t seeking carpentry experience, numerous easy-to- assemble prefabricated shed kits are available on the market.
Prefabricated sheds include traditional wood models, metal units, and high-impact vinyl. The kits come with materials precut and ready to assemble. With basic skills, a tape measure, level, hammer, screwdriver, and a helper, you can erect one in no time. The kits come with detailed instructions specific to the model, so the steps shown here are general in nature to give you an idea of just how easy it is to put a kit shed together.
PREPARE A FOUNDATION AND FLOOR:
Most shed kits do not include floors; they can be purchased as an option, or it’s easy to build your own. A solid floor and foundation beneath a shed will prolong its life.
There are two basic options for floors: a concrete slab or a plywood floor constructed on top of 4x4 treated timbers, which in turn rest on a gravel base. In either case, lay out the area with batter boards and mason’s lines. Remove the sod from the area, taking about 4 inches around the perimeter of the shed.
If you’re going to pour a concrete slab floor, add a 3-inch sand base on the earth. If the shed is extremely large, check with local building codes for foundation and footing requirements. Pour the concrete into 2x4 forms so the top of the slab is 3 - 4 inches above ground level. You may have to place anchor bolts in the concrete for the shed walls, depending on the manufacturer’s instructions,
For a plywood floor, excavate an additional 4 inches and place 4 inches of gravel on the earth. Set three or more (depending on the size of the shed) 4x4 pressure-treated timbers on the gravel, making sure they are level in all directions, Using pressure-treated 2x4s, build a floor frame on top of the timbers with joists spaced 16 - 24 inches on center, depending on the size of the shed.
Nail / pressure-treated plywood on top of the floor frame.
