When comparing apartments in Chennai, the total area shown in a brochure may not represent the space available inside the home. Carpet area, built-up area and super built-up area measure different parts of an apartment, so two flats advertised with similar overall sizes can provide different amounts of usable indoor space. The most reliable starting point is the carpet area disclosed for the exact unit. Under the Real Estate (Regulation and Development) Act, 2016, carpet area is the net usable floor area of an apartment. It excludes external walls, service shafts, an exclusive balcony or verandah, and an exclusive open terrace, while including the area occupied by internal partition walls. This guide explains carpet area vs built-up area vs super built-up area, how the measurements differ, and what Chennai homebuyers should verify before comparing properties. Carpet Area, Built-Up Area and Super Built-Up Area at a Glance Area term What it generally represents Important point for buyers Carpet area Net usable internal floor area, with inclusions and exclusions defined under RERA Use this as the main size measure when comparing apartments Built-up area Carpet area plus other components such as wall areas and, depending on the stated method, balcony space The calculation is not presented as a single standard formula under RERA; request a written breakup Super built-up area A broader marketing or saleable measurement that may add a proportionate share of common areas to the built-up area There is no universal loading percentage; ask what has been included The same term can be used differently across brochures and resale listings. Always rely on the approved documents and the written area statement for the particular apartment rather than on a general percentage estimate. What Is Carpet Area? Carpet area is the most useful measurement for understanding how much space an apartment provides inside the home. It is also the area term specifically defined by the RERA Act. What RERA carpet area includes Carpet area generally covers the net usable floor area within the apartment, including: Living and dining areas Bedrooms Kitchen Bathrooms Enclosed usable spaces that form part of the apartment, subject to the approved plan Area occupied by the apartment’s internal partition walls The last point is important: RERA carpet area includes internal partition-wall area. It should not be described as excluding all internal wall thickness. What RERA carpet area excludes The statutory definition excludes: External-wall area Service-shaft area Exclusive balcony or verandah area Exclusive open-terrace area Common areas outside the apartment Balcony, verandah and terrace measurements may still be disclosed separately. Buyers should check the approved floor plan and area statement to understand how every space has been recorded. What Is Built-Up Area? Built-up area is a commonly used property term, but buyers should not assume that every developer or listing platform calculates it identically. It often starts with the carpet area and then adds certain structural or exclusive components, which may include: Internal and external wall areas Exclusive balcony or verandah area Other areas specifically identified in the project’s calculation Because the exact method can vary, a figure labelled “built-up area” is not enough on its own. Ask for a written calculation showing the carpet area and every additional component included in the built-up figure. What Is Super Built-Up Area? Super built-up area is also commonly described as saleable area. It may include the built-up area of the apartment plus a proportionate allocation of selected common areas. Depending on the project and its stated calculation method, those shared spaces may include: Common corridors Staircases Lift lobbies Entrance lobbies Clubhouse or other shared facilities Other common circulation or amenity spaces There is no single loading percentage that applies to every apartment project. Building design, the number of homes, common-area planning and the calculation method can all affect the difference between carpet area and a quoted saleable area. For that reason, statements such as “carpet area is always 70% of super built-up area” should not be treated as a rule. Why Fixed Area Percentages Can Be Misleading Older property guides sometimes estimate carpet area as a fixed percentage of built-up or super built-up area. Such percentages may be useful only as rough illustrations; they cannot confirm the actual usable area of a specific flat. For example, two apartments can both be advertised as 1,100 sq. ft. of saleable area, but one may have wider corridors or a larger allocation of common facilities. The other may offer a larger carpet area. Only the unit-specific area statement will show the difference. Do not calculate carpet area by applying an assumed percentage to a brochure figure. Obtain the declared carpet area and verify it against the relevant project documents. Illustrative Apartment Comparison The following example is hypothetical and is not connected to any Viva Housing project. Measurement Apartment A Apartment B Quoted saleable area 1,100 sq. ft. 1,050 sq. ft. Declared carpet area 760 sq. ft. 790 sq. ft. Carpet-to-quoted-area ratio 69.1% 75.2% Apartment A has the larger quoted area, while Apartment B provides the larger carpet area in this illustration. This is why buyers should not shortlist homes using the saleable figure alone. The ratio can be calculated as: Carpet-to-quoted-area ratio = Carpet area ÷ Quoted comparison area × 100 Use this only as a comparison tool. It is not a statutory efficiency score, and a higher ratio does not automatically make one project better. Common facilities, layout quality, ventilation, room dimensions, specifications, maintenance costs, and the buyer’s requirements still matter. How to Compare Apartment Sizes Correctly 1. Compare the carpet area of the exact units Compare the declared carpet area, not just the BHK label or the largest number in the advertisement. Two 2 BHK apartments can have different room sizes, circulation space and layouts. 2. Review the floor plan Check room dimensions, furniture movement, door positions, passage space, ventilation, and natural light. A well-planned apartment may feel more usable than a larger but inefficient layout. 3. Request the complete area breakup Ask the developer or seller to identify: Carpet

Construction quality affects an apartment’s safety, durability, comfort and maintenance. Attractive finishes do not show how well the structure, waterproofing, plumbing, electrical work, openings and common areas were executed. The practical question for a Chennai homebuyer is how to check apartment construction quality before buying. This guide explains what you can observe during a site visit, what to ask the developer and when to involve a qualified engineer or property inspector. What Does Construction Quality Mean in an Apartment? Construction quality combines design, specifications, materials, workmanship, supervision, testing and defect correction. It covers the structure and foundation as well as walls, waterproofing, plumbing, electrical work, doors, windows, flooring, finishes and shared services. No material or finish proves overall quality. Performance also depends on correct storage, installation, supervision and testing. Compare written specifications with accessible conditions and seek help for matters that cannot be judged visually. Why Construction Quality Matters to Homebuyers Safety and durability: Structural work must suit the project’s design and conditions. A normal site visit cannot certify structural integrity. Repairs and maintenance: Sound waterproofing, plumbing, electrical installation and workmanship can reduce avoidable defects, although every building needs maintenance. Everyday comfort: Ventilation, heat exposure, window sealing, drainage and sound transmission affect daily living. Marketability: Upkeep and dependable systems may support buyer confidence, but location, age, demand, amenities and market conditions also influence resale. Quality does not guarantee appreciation. Construction Quality Checklist: 9 Things to Check Before Buying an Apartment Use visible conditions to identify questions, not to make a structural diagnosis. Where possible, inspect the exact unit, compare it with written specifications and document concerns. 1. Structural System and Foundation Ask about the structural system, consultant and available specifications. Where relevant, ask whether a geotechnical investigation informed the foundation design. Visual observation cannot confirm structural safety; use a qualified engineer for verification. 2. Walls and Plastering Look for cracks, uneven surfaces, damp patches, peeling paint and poorly finished junctions. Cracks can have different causes, so record their locations and request an explanation or professional assessment rather than diagnosing them yourself. 3. Waterproofing and Water Seepage Check wet areas and accessible parking or basement spaces for dampness, stains, peeling finishes or repeated repairs. Ask how waterproofing was tested and whether floors drain correctly. 4. Flooring and Tiling Check whether floors appear level, tiles align, joints are consistent and surfaces are free from chips or cracks. With permission, check wet-area drainage. An inspector can assess suspected loose tiles or level differences more reliably. 5. Doors and Windows Open and close accessible doors and windows. Check alignment, locks, hardware, frame sealing and signs of water entry. Compare window positions and ventilation with the approved or agreed plan. 6. Plumbing and Sanitary Work Where permitted, check taps, flushes, visible joints, water flow and drainage. Ask about pipe specifications, pressure testing and concealed-leak procedures. Slow drainage or stains need investigation. 7. Electrical Work Review the electrical specification, switch and socket positions, distribution board, earthing and circuit-protection information. Test points only through the authorised process. Do not open panels or perform technical tests yourself; use a qualified electrician or inspector. 8. Ventilation, Heat and Sound Visit when you can assess sunlight and heat. Check airflow, window operation and external noise. Ask about wall and window specifications if sound matters; one visit cannot establish year-round performance. 9. Common Areas Review accessible corridors, stairs, lifts, parking, terraces, external walls, drainage, utility areas and fire-safety provisions. Note incomplete work and ask who will correct it, by when and how completion will be recorded. Construction Materials: What Should Buyers Ask? Ask for the current written specifications covering structure, walls, waterproofing, flooring, doors, windows, plumbing, electrical work and sanitary fittings. If brands are named, ask whether approved equivalents are allowed and how substitutions are communicated. Do not treat a material name as proof of quality. Suitability also depends on design, storage, installation, supervision and testing. Request written clarification when promised and installed specifications appear different. Construction Quality vs Finish Quality Construction quality Finish quality Structure and execution Paint and decorative appearance Waterproofing and drainage Tile pattern or design Plumbing and electrical systems Fixture and switch appearance Wall and opening performance Interior styling A premium-looking flat is not automatically well constructed. Finishes are easy to see, while important systems may be concealed. Assess both separately. How Is Construction Quality Controlled During a Project? Quality should be managed throughout construction, not checked only after painting. A project-level process may include: Approval and verification of specified materials. Site supervision during each construction stage. Stage inspections for structural, masonry and service work. Workmanship checks before concealed work is covered. Testing of waterproofing, plumbing and electrical installations as applicable. Recording and correcting defects. Pre-handover inspection and closure of pending items. Ask which checks apply to the exact project and what buyer-visible records or explanations are available. Does RERA Guarantee Construction Quality? No. RERA registration is not an independent quality certificate for every building element. The Real Estate (Regulation and Development) Act creates disclosure and promoter obligations, including adherence to sanctioned plans and specifications. Section 14(3) addresses specified structural, workmanship, quality and service defects reported within five years from handover, with a rectification duty under the Act. They do not replace inspection or technical advice. Where applicable, verify the project on the official TNRERA portal and consult Viva Housing’s p/roperty legal guide. Ready-to-Move vs Under-Construction: How to Check Quality Ready-to-move apartment Under-construction apartment Inspect the exact unit and common areas Review plans, specifications and current site progress Check visible seepage, finishes and operation Ask how each stage is supervised and tested Test permitted plumbing and electrical points Compare installed work with declared specifications Record defects before handover Visit only at permitted stages and follow site-safety rules Review completed-building maintenance Assess the developer’s project-specific transparency and records A completed home permits more direct inspection; an unfinished home requires greater reliance on documents, permitted observations and professional expertise.

Buying a home is one of the biggest investments you’ll ever make—not just financially, but emotionally as well. In a city like Chennai, where the real estate market is growing rapidly, especially in up-and-coming areas like Pozhichalur, Pammal, and Pallavaram, it’s essential to approach the process with a clear understanding of your rights, responsibilities, and legal protections. An apartment sale agreement is more than just paperwork—it’s the legal foundation of your ownership. Here’s a comprehensive checklist of what to look for before you sign on the dotted line. 1. Verify the Title of the Property Instead of only checking the flat floor plan, start with the basics: who owns the land and has the legal right to sell it? Insist on seeing the original title deed, parent documents, and encumbrance certificate (ideally for the past 30 years). This confirms that there are no outstanding loans, liens, or legal disputes attached to the property. Inheritances, partitions, or joint ownerships should be disclosed clearly. If the property is part of a larger layout or township, verify the layout approval and land-use classification. 2. Confirm RERA Registration RERA (Real Estate Regulatory Authority) is a safeguard for homebuyers. In Tamil Nadu, any project with over eight units or a land area exceeding 500 sq m. must be registered under RERA. The builder should have a valid registration number, which you can verify on the Tamil Nadu RERA website. This ensures that the project complies with delivery timelines, financial disclosures, and legal transparency and zoning norms like floor area ratio, reducing your risk as a buyer. 3. Understand the Payment Schedule Most new construction projects in Chennai offer a construction-linked payment plan, where instalments are paid based on completion milestones (foundation, plinth, slab, etc.). However, some builders ask for bulk payments early in the process, even before physical work begins. Review the payment terms and negotiate if needed. Ensure the plan aligns with your bank loan disbursement and is documented in the agreement. A well-structured plan minimizes financial stress and aligns builder accountability with your investment. 4. Evaluate the Sale Agreement Clauses Every clause matters. Here are some red flags and essentials to look out for: It’s wise to have a real estate lawyer review the agreement. Even minor wordings can carry serious implications. 5. Know the Cancellation and Refund Terms Circumstances change, and you may need to cancel the booking. The agreement should clearly specify the cancellation policy: whether a percentage is forfeited, if the refund is immediate, or if there’s a processing timeline. Trusted developers will outline this transparently. Avoid house builders who rely on vague or verbal assurances. 6. Confirm Included Amenities and Specifications Don’t get carried away by glossy brochures or model apartments. The sale agreement must list all specifications in writing: flooring quality, bathroom fittings, electrical points, water supply, elevators, fire safety systems, and so on. If a gym, park, or clubhouse is promised, check for timelines and whether they’ll be functional at the time of handover. This prevents future disputes and ensures your expectations are legally backed. 7. Registration and Legal Charges In addition to the base property cost, you’ll need to account for: Check if these are included in your overall price or need to be paid separately. Knowing this upfront helps you avoid budget overruns. Also, be cautious of extra charges for car parking, power backup, water connections, or maintenance deposits. Reputed developers usually disclose these upfront, but it’s wise to get everything in writing.
