THE ARCHITECTURAL AREA
AND VOLUME OF BUILDINGS
Establishing Definitions for the Architectural
Area and Architectural Volume of Buildings
ARCHITECTURAL AREA OF BUILDINGS
? The architectural area does not include such features as pipe trenches, exterior terraces or
steps, chimneys, roof overhangs, etc.
ARCHITECTURAL VOLUME OF BUILDINGS
The ARCHITECTURAL AREA of a building is the sum of the areas of the several floors of the build-
ing, including basements, mezzanine and intermediate floored tiers and penthouses of headroom
height, measured from the exterior faces of exterior walls or from the centerline of walls separating
buildings.
? Covered walkways, open roofed-over areas that are paved, porches and similar spaces shall
have the architectural area multiplied by an area factor of 0.50.
The ARCHITECTURAL VOLUME (cube or cubage) of a building is the sum of the products of the areas
defined above (using the area of a single story for multistory portions having the same area on each floor)
and the height from the underside of the lowest floor construction system to the average height of the
surface of the finished roof above for the various parts of the building.

The STANDARD NET ASSIGNABLE AREA is that portion of the area which is available for assignment or rent-
al to an occupant, including every type of space usable by the occupant.
The Standard Net Assignable Area should be measured from the predominant inside finish of permanent
outer walls to the office side of corridors or permanent partitions and from center line of adjacent assigned
spaces. Where there are interior spaces surrounded by corridors, measurement shall be from the inside face
of enclosing walls. Included should be space subdivisions for occupant use; i.e., offices, file rooms, office
storage rooms, etc. Deductions should not be made for columns and projections necessary to the building
or for partitions subdividing space.
NOTE: There are two variations of the Net Area which may be useful:
(1) Single Occupant Net Assignable Area includes the space from the inside finish of exterior walls to the
office side of permanent partitions and including toilets. The Single Occupant Net Assignable Area is dif-
ferent from the Standard Net Assignable Area by the addition of corridors and toilets, but excludes elevator
shafts, elevator lobbies, stair enclosures, mechanical equipment rooms and electrical closets.
(2) Store Net Assignable Areas are from the exterior front face of the building or store front line througn ti,
the exterior rear face of the building and from center line to center line of walls between adjacent spaces.
