Really, is the glazing requirement that high?
A high percentage of dwellings would fail this rule in my opinion.
So a bedroom of 12sqm floor area would need a window/s an area of 2.4sqm?
So if it had a window 1.8m wide x 1.2m high, it would fail?
How's this for a crazy layout, 3 internal bedrooms with no windows !!!
