Difference Between Built-Up Area and Floor Area
What Is A Built-Up Area?
A built-up area is a total space created within the external perimeter walls of a building or premise.
It is calculated by adding the carpet area – which refers to all the usable space – with the wall thickness and any areas that are not useable, such as balconies, terraces, or flower beds. As such, it is always greater than just the carpet area alone.
What Is The Meaning Of Floor Area?
Floor area refers to the total area of a building, measured from the outer surface of its walls including areas of lobbies, cellars, elevator shafts, and in multi-dwelling buildings all common spaces. It does not include any balconies as part of this area.
Floor area is an important metric for determining the size and value of a building or property; it’s typically used by architects, real estate agents, and home buyers to evaluate how much space there is inside a given structure.
What Is Built-Up Area Vs Floor Area?
The built-up area is the total space a property uses, including the Carpet Area, Interior and Exterior Wall areas, Balcony, and any Corridor if applicable.
The Built-up area measurement is 10-15% greater than the Carpet Area, so for example, if the RERA Carpet Area is 1211 sq ft, then the Built area would be 1332.1 sq ft or more, depending on other features.
The Floor Area is different from the Built-up Area as it is a measure of just one floor’s living space, excluding ceilings and walls – usually measured in square footage or meters. Therefore, when looking at properties and their measurements, it’s important to note which type applies as they are not interchangeable.
What Is The Difference Between A Built-Up Area And A Carpet Area?
The difference between the built-up area and the carpet area lies in the fact that the carpet area is the actual usable floor space and includes only the space that can be covered with a carpet. In contrast, the built-up area includes the carpet area plus any external walls.
Carpet area is calculated as the internal length multiplied by the internal breadth of a room and considers voids between rooms.
On the other hand, the built-up area considers factors such as staircases, elevator lobbies, and terraces that add to an apartment unit’s square feet. Thus, it is usually higher than the carpet area due to extra additions.
How Do You Calculate The Built-Up Carpet Area?
The calculation of the built-up carpet area is fairly straightforward. It starts with finding the built-up area of a room or floor space. This can be measured by simply multiplying the length and breadth of the room, and it will give you the total area in square feet (sq ft).
Once you have the built-up area, you should calculate 70% out of this; that is your carpet area. For example, if your built-up area is 1000 sq ft, the carpet area will be 700 sq ft (i.e. 70 percent x 1000 = 700).
Thus, to find out your carpet area in any given case, all you need to do is compute 70 percent of the built-up area and that will be your carpet area.
