Would be interested to know peoples view please on ventilation for suspended floors. Let's say a house has timber suspended floors, but the back section of the house is getting backfilled and changed to solid to tie in with a solid floor extension that is being built. So front room will get ventilated by air bricks at front of house and hallway will get air from side of house. Will the front room sub floor be ok with just ventilation coming from front of the house?
