shall not exceed twice the width of that street.
(b) A main wall fronting but not abutting on a street shall nut project through a line drawn at an angle of 76 degrees with the horizontal from the boundary of the site abutting the street at a height equal to twice the width of such
Street:
Provided that in either case the appropriate permitted height may be exceeded where the area of the whole wall does not exceed the length of the frontage times such permitted height.
(2) Where a site abuts on two streets forming a corner the permitted heights of the walls of the building fronting such streets may be increased on each facade for a distance from the corner equal to that of the wider street :
Provided that the sum of the areas of such walls shall not thereby be increased by more than the product of the widths of the two streets.
(3) For the purpose of this regulation-
(a) "main wall" means the wall of the building fronting the street from the ground level to the top of the coping, parapet, or eaves, measured from the mean level of the street on which it fronts, and shall be deemed to include all windows and openings;
