Calculate the super built-up area of your flat from its built-up area, including common spaces like lobbies, lifts, and staircases.
The share of common spaces (lobby, parking, gym, elevators) added to the built flat space (typically 20%-40%).
The **Built-Up Area** is the physical boundaries of your apartment, which includes the usable carpet area plus inner/outer wall thickness and balconies.
The **Super Built-Up Area** is the total saleable space builders charge you for. It includes your personal Built-Up Area plus a proportionate share of all common residential spaces.
Super Built-Up Area = Built-Up
Area * (1 + Loading Factor %)
Usually, common amenities and lobbies add a
loading factor of 15% to 40% on top of the built-up space.
Load common flat sizes to check expected super saleable spaces:
Super built-up area is commonly used by developers for property pricing because it reflects both private living space and access to shared amenities such as lobbies, elevators, clubhouses, and corridors.
When comparing multiple properties, relying only on the saleable area can be misleading. Reviewing carpet area alongside super built-up area provides a clearer picture of the actual usable space you receive.
Many residential societies calculate maintenance fees based on super built-up area. A larger super built-up area may result in higher recurring maintenance costs even if the usable living space remains similar.
Understanding super built-up area helps buyers evaluate property pricing, compare projects fairly, estimate long-term ownership costs, and avoid confusion between advertised area and actual usable space.
