Distances between windows (of habitable rooms)

This does NOT APPLY to high level windows if they have a maximum cill height of 1.5m above room floor level. Exceptions to this policy will only be made where they can be shown to be justified by the particular circumstances.

FOR A GIVEN ANGLE BETWEEN THE HABITABLE ROOM WINDOWS OF BUILDINGS A AND B THE TABLE SHOWS THE MINIMUM DISTANCE IN METRES REQUIRED BETWEEN THE WINDOWS. DISTANCES AND ANGLES IN BETWEEN THOSE SHOWN IN THE TABLE SHALL BE IN PROPORTION TO ONE ANOTHER.

Method

Draw the shortest line between two habitable room windows.
Determine Angle A and B.
Using Angles A and B and the table overleaf the minimum distance permitted between the two windows can be found. e.g. A = 60 B = 80 min. distance = 16m
