Why an apartment’s advertised size can be confusing
Imagine comparing two three-bedroom apartments in Gurugram. Both appear spacious in the brochure, yet the actual living rooms, bedrooms and storage areas feel different during a site visit. One reason may be that the advertised figures refer to different types of area. A single square-foot number does not always describe how much space a family can use inside the home.
For buyers exploring Gurugram’s high-rise apartments, low-rise independent floors or housing projects around Sohna, the best starting point is the RERA carpet area shown in the project disclosures and proposed agreement. It gives you a more consistent basis for comparing units than a promotional headline alone.
What is RERA carpet area?
Section 2(k) of the Real Estate (Regulation and Development) Act, 2016 defines carpet area as the net usable floor area of an apartment. Importantly, it includes the area occupied by internal partition walls. It excludes external walls, service shafts, exclusive balconies or verandahs, and exclusive open terraces.
In everyday terms, spaces within the apartment such as its living room, bedrooms, kitchen, bathrooms, internal passages and internal partition walls belong in the RERA carpet-area assessment. A balcony can be valuable for lifestyle, but it is disclosed separately rather than counted as RERA carpet area.
The phrase “carpet area” does not mean that you can literally cover every square foot shown with a carpet: internal partition walls count under the legal definition. For furniture planning, read the dimensioned floor plan in addition to the carpet-area number.
How is built-up area different?
“Built-up area” is a frequently used market expression, commonly referring to the apartment space together with the area occupied by certain walls and, depending on the convention used, other attached areas. The expression does not have the same standardized definition in Section 2(k) as RERA carpet area.
If a marketing sheet quotes built-up area, ask the seller for the exact calculation and a component-wise breakdown. Do not assume that “1,200 sq ft built-up” on one brochure is directly comparable with “1,200 sq ft built-up” on another.
What does super built-up area mean?
“Super built-up area” or “super area” is another market expression. It commonly refers to the apartment area plus an allocated share of certain common facilities such as lift lobbies, corridors or other shared spaces. The components and allocation method can vary, so the number may not tell you how much floor area exists inside your unit.
This distinction matters because a resident uses a lift lobby differently from a living room. Shared amenities are important to daily life, but their notional allocation should not be confused with the private area in which you place furniture, work from home or spend time with family.
Haryana RERA Gurugram introduced regulations in 2021 requiring the sale of apartments/floors in the projects covered by those regulations on a carpet-area basis. Buyers should still review the present project-specific disclosures and agreement, especially when considering older transactions or resales, rather than assuming the wording of every advertisement is correct.
A simple comparison: two hypothetical homes
Suppose Home A has 950 sq ft of disclosed RERA carpet area and an illustrative all-in acquisition cost of ₹95 lakh. Home B has 1,020 sq ft of disclosed carpet area and an illustrative all-in cost of ₹1.02 crore. These figures are arithmetic examples only—not actual Gurugram market quotations or listed property offers.
On this simplified basis, Home A costs ₹10,000 per sq ft of carpet area (₹95,00,000 ÷ 950), while Home B also costs ₹10,000 per sq ft (₹1,02,00,000 ÷ 1,020). Home B provides 70 more sq ft of disclosed carpet area, but the two options tie on this particular measure.
Now imagine that one brochure highlights a much larger “super area” than the other. That figure alone does not establish which home gives you better value. Price per sq ft of RERA carpet area is a useful comparison tool, but it is not a complete buying decision: condition, location, construction quality, layouts, service levels and ongoing charges also matter.
How to compare two floor plans without getting misled
First, identify the exact tower, floor and unit type. Request a dimensioned floor plan for each specific configuration, not just an attractive representative layout. Confirm that the stated RERA carpet area belongs to the same unit configuration as the plan.
Second, compare room dimensions. Look at bed placement, wardrobe depth, dining space, kitchen movement, bathroom layouts, utility areas and the circulation space lost to long corridors. A well-planned smaller home may feel more practical than a larger but awkwardly arranged apartment.
Third, separate inside space from outside space. Record any balcony, verandah or terrace independently, with its dimensions and permitted use. Ask about attached utility balconies as well; their classification should be confirmed from approved plans and the project’s written disclosures.
Fourth, compare building-level features on their own merits. Lifts, corridors, fire-safety arrangements, parking access and amenities affect convenience, but they should not be treated as additional private living-room space.
Which documents should Gurugram and Sohna buyers request?
Begin with the project’s relevant RERA registration and disclosed unit information. Use the Haryana RERA Gurugram project-search portal to identify the correct project or phase and the promoter details. Where necessary, ask for help locating the specific disclosure that corresponds to your unit.
Request the latest applicable floor plan, area statement, draft agreement for sale and a written cost sheet. Confirm whether balcony and terrace areas appear separately and whether the descriptions agree across the documents. If there are changes between brochure, plan and agreement, obtain an explanation in writing.
When evaluating a resale property, request the original allotment documentation, title documents, sanctioned/approved layout information where relevant and any available measurement records. An independent legal adviser or qualified architect can help interpret unusual documents or discrepancies.
Five questions to ask at the site visit
Ask the sales representative: “What is the RERA carpet area of this exact unit?” Then ask, “Can you show me that figure in the approved/project disclosures and draft agreement?”
Follow with: “What are the balcony and utility areas, separately?” “Is this sample unit identical to the configuration I will purchase?” and “What is the total written acquisition cost, including applicable taxes and charges?” These five questions turn a brochure conversation into a document-led comparison.
Bring a measuring tape or a dimensioned furniture plan if you already know the sizes of your beds, dining table or work desks. Also check natural light, ventilation, storage and the usable area around doors and windows.
Does a bigger carpet area automatically mean a better home?
Not always. A family working from home may prioritize a dedicated study and a quieter floor. Another household may value two usable balconies, a convenient kitchen layout or accessibility for older relatives. A larger carpet area can be beneficial, but the right property should fit your specific lifestyle and budget.
For buyers considering both Gurugram and Sohna, combine area comparisons with realistic travel times, schools, healthcare access and project documentation. Keep the same evaluation sheet for every shortlisted home so that a single marketing metric does not dominate the decision.
Frequently asked questions
Is a balcony included in RERA carpet area? No. Under Section 2(k), an exclusive balcony or verandah is excluded from RERA carpet area and should be separately disclosed where applicable.
Are internal walls included in carpet area? Yes. Internal partition walls are expressly included in the RERA definition, even though those portions are not open floor on which you can place furniture.
Can I compare two flats using only their advertised super areas? It is not a dependable like-for-like comparison. Ask for each unit’s disclosed RERA carpet area and written floor plan instead.
Is price per carpet-area square foot enough to decide? No. Use it alongside the all-in price, plan efficiency, location, approvals, amenities and ongoing ownership costs.
