My architect's rear elevation plans for our extension mentions "Air brick and cranked ducts from floor void and ex-A.B.S. left unobstructed".
1.What is a cranked duct and ex-ABS?
2. Rather than going with block and beam for the floor construction, we have now gone with concrete slabs as building regs guy said block and beam was not necessary.
Is my builder correct in not putting an air bricks in? We have a flush threshold between the patio opening and the patio.
Thx.
