1. The distance between two houses A and B is 4m. The
property line is in the center between two house exposed
walls. The A house has exposing building face of 10mx3m,
aggregate window area is 12m2. The B house has exposing
face of 10x6m, aggregate window area is 12m2. Check if
the they meet the spatial separation requirement. If not ,
what we can do?
2. How to determine the maximum opening area?1.1.
