Hi,
Just wondered whether it's a definite requirement to lay a concrete floor before using suspended timbers in an extension?
I'm sure I've read here that you can put a permeable membrane down with gravel over it which then allows any moisture to drain?
Is that still possible or do I have it wrong?
