Its all down to loading. A structural engineer I knew worked out that for example a modern brick based conservatory will sit quite happily on well compacted soil in terms of its weight , but the foundation is there to spread the load and sit on sub soil not likely to be subject to ground heave.He only wanted us to dig down to good subsoil even if its only say 18" down.A reinforced raft can sometimes be more convenient.
A couple of years back we built a 40m2 4 storey building on a reinforced raft , but it was on very good ground.Huge weight loading ... it took 23 cubic mtrs of readymix and about 2 ton of steel ! ... let alone the 6000 bricks, 1000 blocks etc etc....
anyway ... back to Phils shed ! :lol
