How to build foundation for outdoors shed building?
You'll have to know where your frost line is. Get your building permits. Look at you tube for tutorials on pouring a foundation for a shed.
Shed foundation is on or above ground level. Nothing to do with frost line. Building permits not needed most of the time. You can check. Can be concrete, patio blocks, or wood.
That's true, I thought when they asked about a shed building it was more than just those little ready made shed size but more like a small barn or garage size. They just don't give enough info for us to answer properly.
If we’re talking a shed kit, then concrete blocks on a compacted bed of gravel, with adequate drainage should work.
I would “corral” the concrete blocks in place with a staked 2x4, if there’s going to be a chance of erosion.
