If you've been comparing floor plans for Century Immencity, you've probably noticed that the quoted sizes — 2,400 to 4,000 sq.ft. — are always listed as super built-up area, not carpet area. Understanding the difference between these two numbers is one of the most important, and most commonly overlooked, parts of evaluating any premium real estate purchase.
What Is Carpet Area?
Carpet area is the actual usable floor space within your apartment — the area you can walk on, furnish, and live in, measured wall to wall, excluding the thickness of the walls themselves. It's the most accurate representation of the real living space you're getting for your money.
What Is Super Built-Up Area?
Super built-up area includes the carpet area plus your proportionate share of common areas — lobbies, staircases, corridors, clubhouse space, and other shared amenities within the building and project. This is the figure developers typically use in marketing and pricing, since it reflects the full scope of what you're paying for, including access to shared spaces.
Why the Difference Matters
The gap between carpet area and super built-up area is known as the "loading factor," and it can range anywhere from roughly 25% to 40% depending on the project's design, amenity density, and building efficiency. This means a unit quoted at 2,800 sq.ft. super built-up area might have a carpet area closer to 1,900–2,100 sq.ft. — a substantial difference that directly affects how much usable living space you're actually purchasing.
For context on how this applies specifically to the smaller configuration, see Inside Century Immencity's 3 BHK Luxe Floor Plan (2400–2800 sq.ft.), and for the larger format, see Century Immencity 4 BHK Apartments: Space, Layout & Price Explained.
Calculating Effective Price Per Sqft
Once you know the carpet area, you can calculate a more accurate "effective" price per square foot — the total price divided by carpet area rather than super built-up area. This number is often 30–40% higher than the super built-up price-per-sqft figure, and it's the more honest metric for comparing value across different projects, since loading factors vary from developer to developer.
Why Loading Factors Vary Across Projects
A higher loading factor isn't necessarily a red flag — it often reflects a project with more generous common amenities, wider corridors, larger lobbies, and more extensive clubhouse facilities, all of which are shared costs baked into the super built-up figure. Given Century Immencity's scale — 50 acres, 14 towers, and an extensive amenity list — a moderately higher loading factor would be consistent with the project's low-density, amenity-rich positioning.
Questions to Ask Before Booking
When evaluating any unit at Century Immencity, it's worth asking the sales team directly for:
- The exact carpet area figure for your specific unit, not just the tower-wide average
- The loading factor percentage applied to that unit
- Whether balcony area is included in carpet area calculations, since practices vary
- A written cost sheet that breaks down price by both super built-up and carpet area
How This Affects Your Furnishing and Interior Budget
Knowing your actual carpet area is also essential for planning interiors and furnishing, since this is the real space you'll be working with — not the marketed super built-up figure. Interior designers and contractors will always work off carpet area measurements, so having this number early helps you budget more accurately for the full cost of moving in.
Final Thoughts
The difference between carpet area and super built-up area isn't just technical jargon — it directly affects the real value you're getting for your money at any price point. Before finalizing a purchase at Century Immencity, always request the exact carpet area for your specific unit, calculate the effective price per sqft based on that figure, and use it as your primary basis for comparing value against other projects in the Jakkur micro-market.
Frequently Asked Questions
Loading factors in this segment typically range from 25% to 40%, reflecting the proportion of common areas and amenities included in the super built-up figure.
Yes, under RERA regulations, developers are required to disclose carpet area explicitly in registered project documentation.
Not necessarily — a higher loading factor often reflects more generous shared amenities and common areas, which can be a worthwhile trade-off depending on your priorities.
Divide the total unit price by the carpet area (not super built-up area) to get a more accurate per-sqft figure for comparison purposes.
Once the project is RERA-registered, exact carpet area figures will be available on the Karnataka RERA portal.
