Carpet Area, Built-Up & Super Built-Up Area: A Plain English Guide for Buyers
Confused by carpet area and loading factors in real estate? Learn what each term means and how RERA protects your purchase in Thane.
Navigating property measurements can be confusing. Here is a simplified breakdown of real estate area definitions under current regulations.
Carpet Area (The RERA Standard)
Carpet area is the net usable floor space inside the apartment where you can literally lay a carpet. Under MahaRERA, developers MUST quote all prices strictly based on carpet area.
Built-Up Area
Includes carpet area plus the thickness of internal/external structural walls and private balconies.
Super Built-Up Area & Loading
Super built-up area adds a proportionate share of common areas (lobbies, stairs, lift shafts, clubhouse). The difference between carpet and super built-up is known as 'loading' (typically 30-40% in luxury projects). Always evaluate value on a pure carpet area basis using our Valuation Guide.
Is developer pricing in Thane based on carpet area?
Yes, under MahaRERA, all property sales agreements must legally specify and price based on carpet area.
What is an acceptable loading percentage in luxury projects?
In amenity-rich luxury townships, carpet-to-super built-up loading generally ranges between 30% and 38%.
