Do foundations need a level?

Foundations should be placed below the level where annual seasonal movement would be expected to occur. This level varies according to the volume change potential (VCP) of the soil i.e: High VCP = 1.0 m minimum depth, Medium VCP = 0.9 m minimum depth, Low VCP = 0.75m minimum depth.

Is it possible to have a building without having the foundation resting on the ground?

So, Can You Build a House Without a Foundation? The simple answer is that of course, you can — as long as you don’t need it to stand for long. Historically, houses without foundations have tended to be simple affairs, built around an earth floor, which weren’t designed to last.

If there are, or were, trees nearby, depths of up to 3m may be necessary.
