    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?
