Carpet Area & Super Built-up Area Guide for Sector 150 Noida 2026
Prices & RERA details verified against the UP RERA portal, June 2026.
Carpet area is the net usable floor space inside your apartment walls, while super built-up area adds your share of common spaces like lobbies, staircases and the clubhouse. When you buy an apartment in Sector 150 Noida, the carpet figure — not the super built-up number — is what you actually get to live in. RERA rules make carpet area the legal basis for sale, so it is the one measurement that decides value.
This guide explains what each area term means, how the loading factor links them, and why RERA settled on carpet area — with Prestige Bougainvillea Gardens and its verified carpet sizes as the worked example. Every size and price below is drawn from the project's own floor-plan data.
Carpet, Built-up and Super Built-up Area — What Each Term Means
| Area term | What it includes | What it excludes | RERA sale basis? |
|---|---|---|---|
| Carpet area | Net usable floor inside walls — rooms, kitchen, internal partition walls | External walls, balcony, common areas | Yes — mandatory since 2017 |
| Built-up area | Carpet area plus wall thickness and the balcony | Shared and common areas | No |
| Super built-up (saleable) | Built-up area plus a share of lobbies, stairs, corridors and clubhouse | Nothing further — it is the largest figure | No — cannot be the price basis |
Definitions per the RERA framework — confirm the exact carpet and balcony figures in the developer's cost sheet before booking.
What Is Carpet Area?
Carpet area is the net usable floor area within the walls of your flat — literally the space you could cover with a carpet. It counts the bedrooms, living and dining space, kitchen, bathrooms and the internal partition walls, but not the external walls, the balcony or any shared space. This is the number that tells you how much room you truly own.
Because carpet area strips out everything you cannot use, two flats sold as the same "size" can differ once you read the carpet figure. A buyer comparing homes in Sector 150 should always line up carpet against carpet. That single habit prevents most size-related surprises at handover.
What Is Super Built-up Area — and the Loading Factor?
Super built-up area is the carpet area plus your proportionate share of the building's common spaces — the lobby, staircases, lift shafts, corridors and the clubhouse. It is always the largest of the three figures, which is why an older brochure quoting super built-up makes a flat look bigger than it lives. It is a real cost the developer recovers, but it is not usable floor.
The gap between carpet and super built-up is the loading factor, written as a percentage. In the Noida market it usually runs about 25 to 35 percent, so a 1,000 sq ft carpet flat may be quoted as roughly 1,250 to 1,350 sq ft super built-up. A lower loading factor means more of what you pay for is space you can actually use.
Why RERA Made Carpet Area the Legal Standard
The Real Estate (Regulation and Development) Act ended the old habit of pricing homes on inflated super built-up figures. Since 2017 a developer must state the carpet area and sell on it, so buyers compare like with like and pay for space they can occupy. The UP RERA registration records the carpet area, making it the figure you can verify rather than take on trust.
For a buyer in Noida, this means the price per square foot in the cost sheet should be a per-carpet rate. If a seller quotes a low rate on super built-up area, convert it to carpet before you judge it — the real cost of usable space is often higher than the headline number suggests.
How to Convert Between Carpet and Super Built-up
The maths is simple once you know the loading factor. Multiply the carpet area by one plus the loading factor to get the super built-up area — a 1,000 sq ft carpet flat at 30 percent loading becomes 1,300 sq ft super built-up. To work the other way, divide the super built-up figure by one plus the loading factor to recover the carpet area.
Two checks keep you honest. First, ask for the loading factor in writing, because a vague "about 30 percent" hides real money. Second, always convert competing quotes to the same basis — carpet — before comparing, so a high-loading project does not look cheaper than it is.

Checklist: Verify Carpet Area Before You Book
A clear read on area rests on a short, repeatable set of checks:
- 1. Ask for the carpet area in writing: get the RERA carpet figure on paper, not a spoken "about" number.
- 2. Check the agreement: confirm the same carpet area appears in the builder-buyer agreement.
- 3. Confirm the loading factor: ask how carpet was converted to any super built-up number quoted.
- 4. Match price to carpet: make sure the per-square-foot rate is on carpet area, not super built-up.
- 5. Verify on UP RERA: once registered, cross-check the carpet area on the portal against your document.
Conclusion
Carpet area is the honest measure of an apartment — the usable space you own — while super built-up area is a larger figure that folds in shared spaces through the loading factor. In Sector 150 Noida, RERA makes carpet the legal basis for sale, so read every price as a per-carpet rate and convert competing quotes to the same basis before you decide. Do that, and no flat will feel smaller than the brochure promised.
Prestige Bougainvillea Gardens quotes on carpet area, with 1, 2 and 3 BHK homes from ₹94.25 lakh at ₹14,500 per sq ft and carpet sizes from 650 to 1,900 sq ft. To see the exact carpet and balcony figures for each layout, request the floor plan PDF and the latest cost sheet.
Frequently Asked Questions
1. What is the difference between carpet area and super built-up area?
Carpet area is the net usable floor space inside your apartment walls — the space you can lay a carpet on. Super built-up area adds your proportionate share of common spaces like lobbies, staircases, corridors and the clubhouse. Super built-up is always larger, so the same flat looks bigger when quoted on super built-up area.
2. Is carpet area or super built-up area used for pricing in Sector 150 Noida?
Since the RERA rules took effect in 2017, developers must sell and quote apartments on carpet area, not super built-up area. In Sector 150 Noida a base rate is applied to the carpet area to arrive at the price. Always confirm the rate is quoted per carpet square foot before you compare two projects.
3. What is the carpet area of apartments at Prestige Bougainvillea Gardens?
Prestige Bougainvillea Gardens offers carpet areas of 650 to 750 sq ft for 1 BHK, 1,000 to 1,300 sq ft for 2 BHK and 1,450 to 1,900 sq ft for 3 BHK. At a base rate of ₹14,500 per sq ft, prices start at ₹94.25 lakh for a 1 BHK, ₹1.45 crore for a 2 BHK and ₹2.10 crore for a 3 BHK.
4. What is loading factor and how much is it in Noida?
Loading factor is the extra area added to carpet area to reach the super built-up area, expressed as a percentage. It covers your share of common spaces. In the Noida market it usually runs about 25 to 35 percent, so a 1,000 sq ft carpet flat can be quoted as roughly 1,250 to 1,350 sq ft super built-up. A lower loading factor means more usable space for the money.
5. Does carpet area include the balcony?
Under the RERA definition, carpet area is the net usable floor area within the walls and does not include the balcony or open terrace, though it does count internal partition walls. The balcony is measured and disclosed separately. Ask for the carpet area and balcony area as two separate figures in the cost sheet.
6. How do I verify the carpet area of a flat before booking?
Ask for the carpet area in writing, check that the same figure appears in the builder-buyer agreement, and confirm the loading factor used to reach any super built-up number. Once the project is registered, the carpet area is filed on the UP RERA portal, where you can verify it against the sales document.
