Building a 12×12 cinderblock shed

Couple ways to do this, depending on how permanent you want the shed to be.

First, you can form a 12×12 slab by using a 2×4 or 2×6 on the outside perimeter, pour a slab in the form, then remove the form.

Your wood walls sit directly on the slab, with a treated lumber 2×4 as the bottom plate on the wood wall.

This assumes you have a fairly level place to work with.

2nd:

You can set block piers in the corner and maybe one centered along the wall that your floor joist run too……..these piers can be set in a bed of gravel alone, since this building will weigh very little. This is a good way to go if your ground slopes as you can vary the depth of your starting level and the number of block needed on any one pier to come up with a level top to all the block. Once you have that, you simply build a conventional floor system on the top of the piers……I probably wouldn’t even anchor it to them, but you could pour them full of concrete mix and sink an anchor bolt in it if you like……..and build the building on from there.

You’ll of course want to check for any local codes and setback requirements, but here, you can do about anything you want with such a small building.

3rd

This is the way we used to build them at the Voc School I taught……We used a 4×6 salt treated skid under the 12′ width at about 30″ in from the outside edge on both sides and framed a conventional floor of 2x6s on top that. The students built a LOT 12×16 buildings that way, then we jacked them up, set on a trailer and delivered them to whoever bought it…..we just rolled them off the back of the trailer in their yards.

Go around to places that sell utility buildings and look at the construction and you’ll see what I’m talking about.

One BIG advantage of this is you can sell the thing later if get tired of it or decide to move and the new owner doesn’t want it.
