Definition
Built-Up Area
Built-up area is the carpet area of a flat plus the area taken up by internal walls and usually balconies — essentially the total area of the unit itself.
It sits between the smaller carpet area (usable space) and the larger super built-up area (which adds a share of common amenities). Built-up area typically exceeds carpet area by a notable margin because it counts wall thickness, ducts and balconies that you cannot fully 'use' as floor space.
When evaluating a property, knowing the built-up figure helps you understand how much of the advertised size is walls and structure versus usable room. Since RERA requires pricing on carpet area, treat built-up and super built-up numbers as context, not the basis for comparing value.
