What you actually use — floor space inside walls
1,000 sq ft
Built-up Area
Carpet + walls + balcony area
1,300 sq ft
Super Built-up Area
Built-up + share of common areas (lifts, lobby, stairs)
1,625 sq ft
Carpet-to-Super Built-up Efficiency
⚠️ Average — typical for high-rise apartments. Compare with other projects before deciding.
RERA Compliance
- • RERA mandates pricing on carpet area only — builders must quote per sq ft rate on carpet area
- • Carpet area includes usable floor space but excludes external walls & balconies
- • Always ask the builder for the loading factor — anything above 35% is high
- • Compare carpet area across projects, not super built-up — that's the real comparison

Carpet Area vs Built-up Area — What's the Difference?
Carpet Area is the actual usable floor area inside your apartment — the space where you can lay a carpet. It excludes walls, balconies, and any shared spaces.
Built-up Area = Carpet Area + thickness of inner/outer walls + balcony/veranda. Typically 25-35% more than carpet area.
Super Built-up Area = Built-up Area + your proportionate share of common areas (lifts, lobby, stairs, gym, clubhouse corridors). This is usually 20-30% more than built-up area.
Under RERA (Real Estate Regulatory Authority), builders are now required to price properties based on carpet area, making it easier for buyers to compare actual space across projects.
