I have a very similar query, There is a 6' by 4' concrete base for a former shed that I want incorporate into a base for a 8' by 6' shed. My plan was to place some concrete slabs alongside the existing base to take the overshoot of the shed-base, ie the wooden joists. Would it benefit to having the wood only in point contact with the ground, or does running a long length of wood in contact with the concrete make sense?

I've been looking at sheds too and the advice my father gave was to sit the floor runners on pressure treated bearers (don't have to be massive) with strips of damp proof membrane between them. Brick/flags also work. Get some shimming material too that you can put above the membrane.
