Shallow 'suspended' floor

[StBernardo]

I have a thin, solid concrete screed for a ground floor (in an old house) which I think contributes to dampness in walls, and a general feeling of coldness. I am not keen on the effort and expense to replace it with (for example) a traditional limecrete screed; with insulation, and underfloor heating. Instead, I am thinking of replacing the concrete with a very shallow wooden floor. Space (headroom) is restricted so the joists would rest on a dampproof membrace and brick/tile bearers. To provide for ventilation I intend to perforate the joists (to allow air to circulate) and attach a low power fan to keep the air moving.

I would be grateful for any comments or advice on this.

Limecrete is a total waste of time and just a "planet saving"fad also your idea won`t work either, sorry
