Wood foundations are typically built using solid concrete leveling blocks which are 8” x 16” and no more than 2” high. Each block is arranged in evenly spaced rows by placing one in each corner and at each break. These concrete leveling blocks will support the floor. If you choose not to use concrete leveling blocks, we recommend using pressure treated lumber to support the wooden floor frame.
Building a 12×20 shed. Thinking about using 2×8 floor joints and rim board with the joists setting on 6×6 pt timbers tucked under the long 20′ sides with a 20′ 4×6 running parallel in the center. There would be support blocks at the 4 corners and in the center of the 12′ width. Then also in the middle of the three 20′ runs. Total of 9 support blocks altogether with them setting on gravel base ground. Does this sound like a good plan to you?
The wooden portabase is a time and cost saving base perfect for garden sheds. The portabase is constructed from timber and comes in a range of sizes to suit different garden buildings. The base features spikes on each corner; these spikes can be sunk into the ground offering a stable base for a garden building. You will need to ensure the ground you install your portabase onto is level otherwise your building could end up getting damaged.
You can make shelves using blocks that are left over when you dismantle the pallets and you could use left over pallet wood or ply wood. I used some old decking off cuts. Drill two blocks on to the wall – good to use a spirit level to get these straight, then lay the pallet wood/ply wood/decking cut to size on top and screw the shelf onto the blocks.
Arch-top windows and a custom door give this shed a high-quality look that belies its low cost and simple construction. The panelized construction technique means you could build the parts in your garage on a rainy weekend and then haul them to the site for assembly. Modest finishes like OSB siding and composite trim and fiberglass shingles help keep the materials cost low. And you’ll save hundreds of dollars by providing your own labor to build the door and windows. The modular construction and wood platform foundation mean you can construct this shed almost anywhere, even on remote or sloping sites. In this article, we’ll show you the basics of how to build the shed and install the windows and doors.
