Understanding Area Terms in Kolkata Real Estate
When evaluating residential apartments in Kolkata, understanding how square footage is measured is essential to evaluating fair pricing per square foot.
### 1. Carpet Area (RERA Mandated)
Carpet area represents the net usable floor area of an apartment, excluding the area covered by external walls, service shafts, and balconies, but including internal partition walls. Under RERA, developers are legally required to quote and register all sales transactions based strictly on carpet area.#
2. Built-Up Area
Built-up area includes the carpet area plus the area of outer walls, balconies, and private terraces. Typically, built-up area is 10% to 15% larger than carpet area.#
3. Super Built-Up Area
Super built-up area includes the built-up area plus a proportionate share of common building areas such as lobbies, staircase wells, elevator shafts, generator rooms, and clubhouses.#
