What are Carpet Area, Built-Up Area, and Super Built-Up Area?

Introduction

When buying a home, one of the most confusing aspects for buyers is understanding the difference between carpet area, built-up area, and super built-up area. These terms directly impact the size of your flat, the price you pay, and the value you get.

In this blog, we’ll simplify these commonly used real estate terms with examples so that you make an informed property decision.

What is Carpet Area?

Definition: Carpet area is the actual usable area inside the apartment—the space where you can lay a carpet.
It includes:
- Bedrooms, living room, kitchen, bathrooms, balconies (if enclosed)
It excludes:
- Common areas like lobbies, lifts, staircases, and external walls

👉 As per RERA (Real Estate Regulatory Authority), builders must sell flats based on carpet area only.

Example: If your flat has a carpet area of 600 sq. ft., you are paying only for the usable space inside the apartment.

What is Built-Up Area?

Definition: Built-up area = Carpet Area + Walls + Utility Spaces.
It includes:
- Carpet area
- Thickness of internal & external walls
- Utility areas like balconies, flower beds, and terraces (partial inclusion)

👉 Built-up area is usually 10–15% more than the carpet area.

Example: If your carpet area is 600 sq. ft., your built-up area may be around 660–690 sq. ft.

What is Super Built-Up Area?

Definition: Super built-up area = Built-Up Area + Common Areas.
It includes:
- Built-up area of the flat
- A proportionate share of common areas like lifts, lobbies, staircases, clubhouses, and amenities

👉 Super built-up area is also called the “saleable area” as builders often calculate the property price based on this figure.

Example: If your built-up area is 690 sq. ft. and you are allocated 110 sq. ft. of common areas, the super built-up area = 800 sq. ft.
