Buying a new home in Visakhapatnam is an exciting milestone, but navigating real estate jargon can quickly become overwhelming. If you are comparing properties, you have likely encountered terms that sound similar but mean completely unique things for your wallet and your living space. Understanding the exact difference between carpet area and built-up area—as well as the super built-up area—is crucial before signing any property agreement.
At Eswari Group, we believe in complete transparency. We explain these terms, how they are calculated, and what you pay for when you buy your dream home.
For a quick breakdown:
- Carpet Area: The actual usable floor space inside your apartment where you can lay a carpet.
- Built-Up Area: The carpet area plus the thickness of the inner and outer walls and the balcony.
- Super Built-Up Area: The built-up area plus a proportionate share of the building’s common spaces (like lobbies, staircases, and elevators).
What is carpet area? (The Usable Space)
The carpet area is exactly what it sounds like: the net usable floor area of an apartment where you can practically lay down a carpet. According to the guidelines set by AP RERA (Andhra Pradesh Real Estate Regulatory Authority), developers must quote prices based on this metric.
What it includes:
- Bedrooms, living rooms, dining rooms, kitchens, and bathrooms.
- The thickness of the internal partition walls inside the apartment.
What it excludes:
- External walls.
- Service shafts.
- Balconies or open terraces.
What is a built-up area? (The Blueprint Space)
The primary difference between carpet area and built-up area lies in the physical structures that enclose your space. The built-up area provides you the total footprint of your specific unit, including the walls that hold it up.
How it is calculated: Built-Up Area = Carpet Area + External Wall Thickness + Balconies/Terraces
Typically, the built-up area is about 10% to 15% larger than the carpet area. While you cannot use the wall space to place furniture, it is a necessary part of your apartment’s structural integrity.
What is a Super Built-Up Area? (The Saleable Area)
Also known as the “Saleable Area,” this is the most expansive measurement. Before RERA standardized property pricing, many builders priced apartments based on the super built-up area.
How it is calculated:
Super Built-Up Area = Built-Up Area + Proportionate Share of Common Areas
Common areas include:
- Elevators and staircases.
- Corridors and main lobbies.
- Clubhouses, gyms, and swimming pools (in some cases).

Why This Matters for Vizag Homebuyers
Knowing the difference between carpet area and built-up area protects you from paying for space you cannot privately use. If a developer quotes a highly attractive price per square foot, check whether they are calculating it based on the super built-up area. A larger super built-up area means higher maintenance costs, even if your actual living space (carpet area) is smaller.

Frequently Asked Questions (FAQs)
1Q: Is the balcony included in the carpet area?
1A: No, according to RERA guidelines, balconies, open terraces, and verandas are excluded from the carpet area. They are, however, included in the built-up area.
2Q: What is the standard difference between carpet area and built-up area?
2A: Generally, the built-up area is 10% to 15% larger than the carpet area, depending on the thickness of the walls and the size of the balconies.
3Q: Why do builders charge maintenance on the super-built-up area?
3A: Maintenance fees cover the upkeep of common amenities like elevators, lobbies, and clubhouses. Since all residents share these facilities, the cost is calculated proportionally based on the super built-up area of each unit.
4Q: How can I verify the exact carpet area of a property I want to buy?
4A: You can verify the exact measurements by checking the property’s official brochure or its registration details on the state’s RERA website. Reputed developers will always list the exact RERA carpet area in their agreements.
