Carpet Area vs Built-Up vs Super Built-Up: What ASBL Loft 1,695 sqft Actually Means
When ASBL Loft prices a 3 BHK at 1,695 sqft, the number on the brochure is the super built-up area. The number on the RERA filing — and in the sale agreement the sub-registrar stamps — is the carpet area, which is 1,050 sqft. The difference is not a trick. It is the proportionate share of common areas (lobbies, lifts, clubhouse, staircases, podium decks) that every buyer in the project funds together. RERA requires the carpet figure to be disclosed; market convention continues to lead with super built-up because that is what you actually pay for.
This guide unpacks the three definitions per RERA Section 2(k), runs the loading-factor math on both Loft variants, compares the project to publicly disclosed numbers on Aparna Sarovar and ASBL Spectra, and shows where on the RERA portal you should verify everything before signing.
The three definitions that matter
Three measurements describe the same apartment. They are not interchangeable and the Real Estate (Regulation and Development) Act 2016 defines exactly one of them.
| Term | What it measures | RERA status |
|---|---|---|
| Carpet area | Net usable floor area inside the apartment walls, excluding external walls, service shafts, balcony, verandah and exclusive open terrace. Includes internal partition walls. This is the area you can physically lay carpet on. | Defined under Section 2(k). Mandatory disclosure in the RERA filing and sale agreement. |
| Built-up area | Carpet area plus the area covered by external walls, internal walls, ducts and the exclusive balcony or verandah. Typically 10 to 15 percent larger than carpet on a comparable 3 BHK. | Not defined by RERA. A pre-RERA convention; still used informally by developers and brokers. |
| Super built-up area | Built-up area plus a proportionate share of common areas — lobbies, lifts, staircases, clubhouse, internal roads, landscaping, security cabins, electrical substations. Computation method is not legally fixed. | Not defined by RERA. The number most marketing collateral continues to quote because all common amenities are proportionately funded by buyers. |
Section 2(k) of the Real Estate (Regulation and Development) Act 2016 is the only statutory definition. The sale consideration and the agreement value are still negotiated on the super built-up figure, but the project must register and disclose carpet on rera.telangana.gov.in before any sale agreement is registered.
ASBL Loft — the actual numbers
ASBL Loft is registered with Telangana RERA under P02400006761. The RERA filing discloses the same internal carpet area on both configurations — the variants differ only in the size of the outdoor living balcony.
| Configuration | Super built-up (quoted) | Carpet (RERA) | Outdoor balcony | Loading factor |
|---|---|---|---|---|
| 3 BHK · 1,695 sqft | 1,695 sqft | 1,050 sqft | 125 sqft | ~38.1% |
| 3 BHK · 1,870 sqft | 1,870 sqft | 1,050 sqft | 260 sqft | ~43.9% |
Loading factor = (super built-up − carpet) ÷ carpet, expressed as a percentage. On the 1,695 sqft variant: (1,695 − 1,050) ÷ 1,050 = 61.4 percent of carpet, or 38.1 percent of super built-up. On the 1,870 sqft variant: (1,870 − 1,050) ÷ 1,050 = 78.1 percent of carpet, or 43.9 percent of super built-up. Both variants share the same internal apartment; the larger variant pays extra for a double-size outdoor balcony plus a proportionately larger share of the common amenities.
Why the 1,695 sqft loading factor is higher than the Financial District average
For a typical premium 3 BHK in Financial District, the loading factor on the smaller variant tends to sit between 28 percent and 35 percent. ASBL Loft sits at approximately 38 percent on the 1,695 sqft variant. The math is explained by what the project chooses to share among 894 owners:
- A 55,000 sqft clubhouse — the largest single amenity block in Financial District. Pool, double-height gym, squash, badminton, co-working, crèche and a multi-sports turf are all loaded proportionately into the super built-up.
- Double-loaded corridors on 10 units per floor across a G+45 tower require wider lobbies and additional lift cores versus a single-loaded 5-units-per-floor layout.
- 4.92-acre footprint with two towers, podium decks, landscaped open spaces and internal driveways — all funded by the 894 buyers via super built-up loading.
- Mivan formwork construction requires marginally thicker structural walls than conventional brick-and-mortar, which adds to the built-up but is a quality decision (5-7 day floor cycle, materially fewer hairline cracks over the building's life).

How Loft compares to other Financial District projects on loading
Loading factor is not the only — or even the most important — quality signal, but it is the one most aggressively used in marketing. Cite the headline carefully and always cross-check on the respective RERA filing.
| Project | Configuration | Super built-up | Carpet (typical range, as disclosed on RERA) | Approx loading |
|---|---|---|---|---|
| ASBL Loft | 3 BHK (1,695 sqft variant) | 1,695 sqft | 1,050 sqft | ~38% |
| ASBL Loft | 3 BHK (1,870 sqft variant) | 1,870 sqft | 1,050 sqft | ~44% |
| ASBL Spectra (sister project, FD) | 3 BHK | ~1,750-1,950 sqft | ~1,200-1,300 sqft | ~30-35% |
| Aparna Sarovar Zenith (Nallagandla) | 3 BHK | ~1,700-2,000 sqft | ~1,200-1,400 sqft | ~28-33% |
| My Home Apas (FD) | 3 BHK | ~1,800-2,100 sqft | ~1,300-1,500 sqft | ~28-32% |
Competitor figures are reproduced from public RERA disclosures and brochure information as of June 2026. Verify the exact carpet area for any specific unit type on the project's RERA filing before signing, since variants within a single project can differ. Loft's higher loading factor reflects the 55,000 sqft amenity block and the 4.92-acre footprint shared across 894 units — more amenity per buyer, less private carpet at the same per-sqft headline.
What you actually use — beyond the carpet number
Carpet is the number that matters for physical floor space. But usable area is not just carpet, especially on the larger Loft variant, where the outdoor living balcony adds a meaningful private zone that is not counted in carpet under Section 2(k).
- 1,050 sqft internal carpet on both variants — 3 bedrooms, 3 bathrooms, kitchen, living and dining.
- 10 feet 5 inches floor-to-ceiling height — 6 inches above the industry standard 9 feet 11 inches, which materially changes the perceived volume of every room without changing the carpet number.
- 125 sqft outdoor balcony on the 1,695 sqft variant and 260 sqft outdoor balcony on the 1,870 sqft variant — excluded from RERA carpet but real, private, fenced space.
- Living room of 16 ft 1 in × 11 ft 10 in (approximately 190 sqft) and a master bedroom that runs 147 sqft (east-facing) to 164 sqft (west-facing).
- 55,000 sqft clubhouse shared across 894 owners — roughly 61 sqft of amenity space per owner, which is what shows up in the loading factor.
Where to verify the carpet area on the RERA portal
- Visit rera.telangana.gov.in and open the project search.
- Enter the RERA registration number P02400006761 and open the project page.
- Download the approved sanction documents. The carpet area per unit type is disclosed in the prescribed Form A annexure and the sale agreement template.
- Cross-check the carpet figure in the registered sale agreement before signing — this is the document the sub-registrar stamps, and any future buyer or bank will reference the agreement carpet number, not the brochure super built-up number.
- If the carpet number in the agreement is materially different from the RERA filing, that is a red flag. Raise it before paying any booking amount.
Why the loading factor is loaded with trade-offs
A common buyer mistake is to chase the lowest loading factor without checking what amenities are being skipped. A 20 percent loading factor in a Financial District project — if the carpet is genuinely disclosed correctly — usually means the project has a token amenity block, narrow corridors, fewer lifts and a small clubhouse. That is fine for a buyer who values private space and does not want to fund shared amenities, but it is not a quality signal on its own.
Conversely, a 45 percent loading factor is acceptable if the shared amenity is something you will actually use. ASBL Loft sits at the higher end of the range because the 55,000 sqft clubhouse is real, operational at handover, and structured as a single double-height amenity block rather than fragmented across multiple smaller facilities. Whether that trade-off is right for you is a personal question — read the project overview and the ASBL portfolio context before deciding.
A worked example — applying loading factor to your shortlist
Pick the project that offers the best private carpet at the price you are willing to pay. The headline super built-up rate is misleading on its own. Worked example on the 1,695 sqft Loft Option A booking:
- Base price: ₹1.94 Cr on 1,695 sqft super built-up = ₹11,445 per sqft super built-up.
- Same base price spread over 1,050 sqft carpet = ₹18,476 per sqft carpet.
- For a Financial District comparable at ₹13,000 per sqft super built-up and a 30 percent loading factor, the implied carpet rate works out to approximately ₹16,900 per sqft carpet. The Loft carpet rate is higher because the loading factor is higher and because more amenity is loaded into the super built-up.
- The trade-off: Loft has December 2026 possession, a contractual rental cushion of ₹85,000 per month till December 2026, and the largest amenity block in Financial District. A 2027-28 possession competitor at a lower carpet rate is a different product even if the per-sqft headline looks better.
See the Financial District rental yield analysis for the full math on how the cushion offsets pre-EMI before possession, and how the post-possession yield compares to the wider Hyderabad market.
The bottom line
ASBL Loft 3 BHKs are quoted at 1,695 sqft and 1,870 sqft super built-up. The RERA-disclosed internal carpet on both is 1,050 sqft. The 1,695 sqft variant adds a 125 sqft outdoor balcony and runs a 38 percent loading factor; the 1,870 sqft variant adds a 260 sqft outdoor balcony and runs a 44 percent loading factor. Both are higher than the Financial District average of 28 to 35 percent because the project includes a 55,000 sqft clubhouse — the largest amenity block in the micro-market — and wider podium decks shared across 894 owners on 4.92 acres.
Cost, GST, stamp duty and registration are computed on the super built-up agreement value regardless of carpet. The sale agreement the sub-registrar stamps will reference the carpet figure per RERA Section 2(k) — verify it on rera.telangana.gov.in against RERA P02400006761 before signing.

Frequently asked questions
What is the carpet area of an ASBL Loft 3BHK?
The RERA-disclosed internal carpet area on both ASBL Loft 3BHK configurations is 1,050 sqft, measured per Section 2(k) of the Real Estate (Regulation and Development) Act 2016 — the net usable floor area inside the apartment walls, excluding external walls, service shafts, balcony and verandah. The 1,695 sqft variant adds a 125 sqft outdoor living balcony; the 1,870 sqft variant adds a 260 sqft outdoor living balcony. The remaining difference between carpet and the quoted super built-up area is the proportionate share of common areas (lobbies, lifts, staircases, clubhouse, internal roads).
What is the loading factor at ASBL Loft?
The loading factor at ASBL Loft works out to approximately 38.1 percent on the 1,695 sqft variant and 43.9 percent on the 1,870 sqft variant, computed on a 1,050 sqft carpet base. For Financial District the typical loading factor on premium 3 BHK projects ranges between 28 percent and 35 percent on the smaller variant; Loft sits a notch higher because the project includes a 55,000 sqft clubhouse (the largest in Financial District) plus extra-wide podium decks, double-loaded corridors and additional lift cores, all of which are proportionately added to the super built-up area.
How is carpet area defined under RERA?
Under Section 2(k) of the Real Estate (Regulation and Development) Act 2016, carpet area is defined as the net usable floor area of an apartment, excluding the area covered by external walls, areas under service shafts, exclusive balcony or verandah area and exclusive open terrace area, but including the area covered by the internal partition walls of the apartment. Every RERA-registered project in India must disclose carpet area in the sale agreement and the project's RERA filing — the developer can quote any other measure in marketing, but the legal sale is on the carpet number.
Why does ASBL Loft quote 1,695 sqft and not the carpet number?
Indian real estate has historically quoted super built-up area because all common-area amenities are proportionately funded by buyers, and the super built-up figure makes the cost-of-ownership comparison clearer across projects with different amenity loads. RERA mandates disclosure of carpet area in the agreement and the RERA portal — which ASBL Loft does at 1,050 sqft — but most marketing material continues to lead with the super built-up number. The sale consideration, GST, stamp duty and registration are computed on the super built-up agreement value regardless.
Is a lower loading factor always better?
Not necessarily. A lower loading factor means a higher proportion of your purchase is inside your flat, which is better if you value private space. A higher loading factor means more of the cost is going into shared amenities — clubhouse, swimming pool, gym, landscaping, lobbies, lifts. ASBL Loft sits at the higher end of the Financial District range because the project includes a 55,000 sqft clubhouse and double-loaded corridors with extra lift cores. If a project quotes a sub-25 percent loading factor in Financial District, that usually signals minimal amenities or aggressive saleable-area accounting — verify the carpet number on the RERA portal before believing the headline.
How can I verify the carpet area of ASBL Loft on the RERA portal?
Visit rera.telangana.gov.in, open the project search, enter the RERA registration number P02400006761 and download the approved sanction documents. The carpet area per unit type is disclosed in the prescribed Form A annexure and the sale agreement template. ASBL Loft discloses 1,050 sqft internal carpet on both 3 BHK variants. The same carpet number appears in the registered sale agreement, which is the document the sub-registrar stamps and that any future buyer or bank will reference.
How does the ASBL Loft loading factor compare to other Financial District projects?
Per public RERA disclosures and brochure information, premium 3 BHK projects in Financial District typically run between 28 percent and 35 percent loading on the smaller variant. ASBL Loft, at approximately 38 percent on the 1,695 sqft variant, runs slightly higher because the project bundles a 55,000 sqft clubhouse (the largest amenity block in Financial District), wider podium decks, additional lift cores and a 4.92-acre footprint that the 894 units share. The trade-off is more amenity per buyer for slightly less private carpet at the same super built-up price — verify the exact comparison on the respective RERA filings before signing.
Does the rental cushion at ASBL Loft pay on carpet or super built-up area?
The ASBL Loft Option A rental cushion — ₹50 per sqft per month till 31 December 2026 — is computed on the super built-up area, the same figure used for the sale consideration. That works out to approximately ₹85,000 per month on the 1,695 sqft variant (rounded from ₹84,750) and ₹93,500 per month on the 1,870 sqft variant. This is a contractual rental payment, not a guaranteed return; the income is taxable under Income from House Property with a 30 percent standard deduction and TDS applies.
