Hi Guys,
I have an architect (technician) popping over tonight to discuss a rear extension that I want to start building shortly. As this will be largely self build/project managed, when chatting with him on the phone he mentioned some cost saving options that we could consider. One was solid aerated blocks with insulation on the inside (which we both agreed was not ideal because of the soft inner surface). Will probably do double skin cavity instead. The other saving he mentioned was a suspended floor instead of solid one. I understand the basic difference between the two, but is there a definate advantage to solid over suspended? The rest of the existing house is suspended.
Off the back of the above question, I'm also curious what is required from a building point of view with a suspended floor. It's not open to the ground below the joists is it? Is there essentially a thin slab with damp proof membrane and insulation or nothing at all?
Thanks
