Any reason not to build house foundations directly on sandstone?

Cheers.

Do you have any choice? What's underneath the sandstone, more sandstone?

None whatever. You will still need a footing or raft.
Possibly added expense in cutting away rock. But the rock may be useful
elsewhere.

It'll need levelling off with concrete, how thick depends on the BCO, but I
can't imagine it would be much as bedrock is more stable than anything man
made.

Can't think of one unless it's really crappy very soft sandstone.

Round here it'll probably be limestone, possibly shale or coal
depending where in the repeated carboniferous sequence you are.
