Building envelope area means all building space and any area (at or above ground level)beneath air= conditioned enclosed building space, excluding: (i) unfinished attic or basement space with no fixed accessway or with less than seven feet of headroom; (ii) pervious area at ground level beneath bay windows, cantilevered space and similar parts of buildings projecting 15 inches or less; and (iii) front porch space that lawfully projects into a front yard (or could lawfully project, if the building were closer to the front street line), (iv) other porch space neither enclosed nor located beneath enclosed building space, and (v) up to 200 square feet of unenclosed buildin. s.ace beneath enclosed buildin' s.ace for features of architectural interest, no one of which encompasses more than 50 square feet. Building envelope area is measured on each floor level using the outer walls (or perimeter) to calculate the area (also including the outer walls of bay windows, cantilevered space and similar space,regardless of the height of the floor). For measurement purposes, eaves, cornices, chimneys, fireplaces, window sills, belt courses and similar non-occupable spaces are disregarded if they comply with the corresponding limits for projections into front yards as specified in Table 7-6 (regardless of where they are actually located).

The width of a column is measured at its thickest point above 3.5 feet above the porch floor. The "maximum-sized porch"is 120 inches deep and extends from one side yard line to the other,but it is limited by the open area requirement for the front yard.
