Carpet area is the usable floor space within an apartment or house. Imagine laying down the carpet; the area it covers is the carpet area. This excludes external walls, utility ducts, etc. It is the space you can freely move around and use.
Built-up area includes carpet area plus the thickness of walls and some additional areas like exclusive balconies and terraces. Built-up area is always more than carpet area, as it essentially considers the total area covered by the home’s walls.
Super built-up area includes the built-up area plus a proportionate share of common areas such as lobbies, staircases, and amenities. SBA is the biggest of the three. It includes the carpet area, the thickness of inner & outer walls, and a proportionate share of common areas like hallways, lobbies, elevators, and amenities. This is the area used to calculate the final price of your apartment, so knowing it is crucial.
Developers use the super built-up area to divide the cost of common facilities and areas among all homebuyers in a building, ensuring everyone contributes to the design & construction of these shared spaces.
No, there is no standard percentage for super built-up area as it depends on the project design. However, it generally ranges between 25% to 30% of the carpet area.
To verify the carpet area, you can measure the dimensions of each room and calculate the total usable area. Comparing this with the developer’s plans can ensure accuracy.
Carpet area is crucial as it represents the actual usable space inside your home. However, understanding built-up and super built-up areas helps you know what you are paying for, including walls and common facilities.
No, carpet area and built-up area are not the same thing. Carpet area is the usable floor space within an apartment, excluding external walls, balconies, etc. Built-up area is larger and includes the carpet area plus the area occupied by walls, balconies, utility ducts, etc.
Carpet area is more important to consider when buying a property as it reflects the actual living space you get. However, it is also important to be aware of the built-up area and super built-up area, to understand the total cost involved.
You can calculate the carpet area of your apartment by measuring the length and width of each room, multiplying the length by width to get the area of each room, and adding the areas of all the rooms to get the total carpet area.
The super built-up area is always higher than the carpet area, as it includes the carpet area plus wall thickness and balconies plus a proportionate share of common areas like hallways, lobbies, elevators, and amenities.
Loading factor is a multiplier applied to the carpet area to calculate the super built-up area. SBA = Carpet Area *(1 + Loading Factor). It accounts for the cost of common areas that are proportionally distributed among all the apartments in the building.
In the above table, you can see areas like the living room, bedrooms, dining room, bathrooms, and inner staircases featured in all three categories. However, outer staircase, lift, lobby, and common gardens are featured under super built-up area. These are not featured under carpet area and built-up area. To simplify, Carpet Area < Built-up Area < Super Built-up Area.
