Carpet Area vs Built-up Area vs Super Built-up Area – Know the Difference

When you're buying a property in Mumbai—whether in Chembur, Ghatkopar, or South Mumbai—understanding real estate jargon is essential. One of the most common areas of confusion among homebuyers is the difference between carpet area, built-up area, and super built-up area. Here’s a simple breakdown to help you decode it:

1. Carpet Area
  • Definition: Actual usable area within the walls of your flat

  • Includes: Bedroom, living room, kitchen, bathrooms

  • Excludes: Walls, balconies, common areas

As per RERA, pricing must be based on carpet area only
Example: If your carpet area is 600 sq. ft., that’s what you can walk on and use

2. Built-up Area
  • Definition: Carpet Area + Thickness of Internal & External Walls + Balcony + Utility Areas

  • Generally 10–20% more than carpet area

Example: If the carpet area is 600 sq. ft., built-up area may be 700–720 sq. ft.

3. Super Built-up Area (also called Saleable Area)
  • Definition: Built-up Area + Proportionate share of common areas (staircase, lobby, clubhouse, etc.)

  • Used by some builders to inflate area and justify price

Super built-up area is not standardized—it varies by builder
Example: Carpet area of 600 sq. ft. might be marketed as 900–1000 sq. ft. super built-up

How This Impacts You
  • Builders may quote lower price per sq. ft. on higher super built-up area to make pricing seem attractive

  • Always ask for RERA Carpet Area and do the price calculation accordingly

Why Carpet Area Matters the Most
  • It’s the actual space you get to live in

  • RERA mandates that builders disclose and price properties based on carpet area

At Chembur Property, we provide clear carpet area disclosures for every listing

Quick Tip to Compare Projects:

Always divide the total price by the carpet area to find the effective rate per sq. ft.

Conclusion

Understanding these area metrics is key to making an informed property purchase. Don't be swayed by inflated super built-up areas—what you use is what you should pay for.
