Why?? That's the big question....


Can anyone give an idea of the cost comparison for concrete and
timber. I'm only looking at a room size of about 4m x 5m.

I don't know, but I should thing that a timber floor will be much
cheaper and easier to install than a suspended concrete one! Even
with insulation and nice boards....
