Understanding Carpet Area, Built-Up Area, and Super Built-Up Area
Buying an apartment, chances are you’ve come across real estate terms like carpet area, built-up area, and super built-up area. While they may sound technical, understanding them is crucial—especially when investing in premium options like 4 BHK luxury apartments. In this guide, we’ll break these terms down in a simple way, so you can make better and more informed property decisions.
What is Carpet Area?
Carpet area is the actual usable area within your home—the space where you can literally lay a carpet. It includes bedrooms, living room, kitchen, bathrooms, and even internal walls. However, it excludes external walls, balconies, common areas, and shafts.
Carpet Area as per RERA Guidelines
According to RERA (Real Estate Regulation and Development Act), carpet area is strictly defined as:
“The net usable floor area of an apartment, excluding the area covered by external walls, areas under services shafts, exclusive balcony or verandah area and exclusive open terrace area, but includes the area covered by the internal partition walls of the apartment.”
This definition was introduced to standardize property measurements across builders and protect buyer interests.
What is Built-Up Area?
Built-up area includes the carpet area + thickness of internal and external walls + balcony area. It represents the total covered space of your apartment unit.
Built-Up Area Calculation Formula
Built-up Area = Carpet Area + Wall Area + Balcony Area
On average, built-up area is around 10-20% more than the carpet area. So if your carpet area is 1,000 sq. ft., your built-up area could be around 1,100–1,200 sq. ft.
What is Super Built-Up Area?
Super built-up area goes a step further. It includes the built-up area plus a proportionate share of common amenities like corridors, staircases, lobbies, lifts, clubhouse, and sometimes even open spaces like gardens and pools.
This is often referred to as the “saleable area”, because it’s the figure developers usually use to quote prices.
How to Calculate Super Built-Up Area
To calculate super built-up area, developers use something called a loading factor.
Formula
Super Built-Up Area = Built-Up Area + (Built-Up Area × Loading Factor)
Or more commonly:
Super Built-Up Area = Carpet Area × (1 + Loading Percentage)
Example:
If your carpet area is 1,000 sq. ft., and the loading is 30%:
Super Built-Up Area = 1,000 × (1 + 0.30) = 1,300 sq. ft.
Impact of Loading Factor on Super Built-Up Area
The loading factor directly impacts how much space you're paying for versus how much you actually use. A higher loading factor means a greater difference between carpet area and super built-up area, reducing the actual usable space.
Difference Between Carpet and Built-Up Area
Why This Matters for 4 BHK Luxury Apartments
If you’re investing in 4 BHK luxury apartments, understanding these measurements becomes even more important. A few hundred square feet difference in loading or built-up calculations can mean lakhs of rupees.
Luxury homes often come with premium amenities—so super built-up areas can be significantly higher due to clubs, pools, and open landscaping. But not all of that is yours to use exclusively.
