I'm planning on building a shed 3.6m by 2.4m and want a concrete base.
It may have to accommodate a cast iron lathe which probably weighs

I want to keep material imports and soil exports to a minimum so am
planning on a 100mm raft with steel reinforcing.

We have sandy soil and quite deep topsoil, I just wonder how much I'll
have to excavate and replace with sub base, any opinions?
