Once you have picked out a set of 12×16 wood shed plans, the next step is to construct the new structure. Regardless of the complexity of the shed design, four basic building blocks are required. Read on to learn more about the frame, floor deck, walls and roof.
Frame & Decking
Before beginning, clear the area upon which the shed will sit of all debris and level the ground (if necessary). Lay sold cinderblocks every few feet along the ground to serve as support for the foundation. Next, set 4×4 posts along the concrete blocks.
Always use pressure-treated lumber as this treatment guards against wood rot. A level, in order to ensure the foundation is even, is also needed for this step.
For a shed the size of a 12×16 building, pouring a concrete slab is also a viable option. To go that route, contact a local contractor to ensure a quality pour.
Once the frame is in place, it is time to build the deck. Two pressure-treated 2×6 timbers cut to length will serve as the long edges of the building. An additional two timbers cut to length will create the wide ends.
A handy tool to have on hand during this step is an air-powered nail gun. Most hardware stores rent this type of tool, as well as others you may need during the building process, for a nominal fee. A screw gun is also a viable option.
After a grid of floor joists are in place between the timbers, install the flat deck. Pressure-treated plywood makes for the best shed floors in terms of durability and affordability. Flat boards are also reasonable material for creating a floor though they may be slightly more expensive.
Walls & Roofing
The completed deck will serve as a work surface for building the walls. Lay the lumber – plywood or OSB (oriented strand board) panels and timber studs – across the shed floor. Then use nails or screws to build the frame.
To add a layer of strength to the frame, secure an additional layer of 2x4s across the top. The final step is to enclose the walls with the plywood or OSB.
Time and again, shed builders report the most challenging aspect of constructing their building was the roof. For this step, secure rafters with wood cleats, then raise the pieces to sit on top of the walls. Thin wood strips – typically 1x6s – keep the rafters together and add an element of structural support. When the frame of the roof is in place, secure roofing sheets followed by shingles or an alternative roof covering.
If the shed plans call for windows, cut them in after the walls and roof are complete. The doors are typically framed in when the walls are erected, but if not, cut them in now as well. This is also the time to cover the exterior with siding or a coat of paint or wood stain. When the structure is complete, it is time to enjoy the shelter you built from 12×16 wood shed plans.
