"1,300 sq ft, 3 BHK" sounds like a clear description, until you walk in and the rooms feel much smaller than you expected. The gap usually comes from which area<\/em> the number refers to. Understanding three terms (carpet, built-up and super built-up area) is one of the easiest ways to compare projects fairly.<\/p>\n\n\n\n

Carpet area: the space you can actually use<\/h2>\n\n\n\n

Under RERA, carpet area<\/strong> has a legal definition: the net usable floor area of an apartment, excluding<\/em> the area covered by external walls, service shafts, exclusive balconies or verandahs and exclusive open terraces, but including<\/em> the area covered by internal partition walls.<\/p>\n\n\n\n

In simple terms, it is roughly the floor inside your home that you can walk on and furnish, plus the thickness of the walls between your own rooms.<\/p>\n\n\n\n

\n

RERA requires promoters to state the carpet area of each apartment in the agreement for sale and on the project's RERA page. Whatever area is used in advertisements, you are entitled to know the carpet area.<\/p>\n<\/div><\/div>\n\n\n\n

Built-up area<\/h2>\n\n\n\n

Built-up area<\/strong> is the carpet area plus the area under the walls (including external walls), and usually your exclusive balcony. It is typically somewhat larger than the carpet area. The exact difference depends on wall thickness and balcony size.<\/p>\n\n\n\n

Super built-up area: your share of the common areas<\/h2>\n\n\n\n

Super built-up area<\/strong> (sometimes called saleable area<\/em>) adds a proportionate share of the building's common areas to the built-up area: lobbies, staircases, lift wells, corridors and, in some projects, the clubhouse and other amenities.<\/p>\n\n\n\n

The difference between super built-up area and carpet area is often called the loading<\/strong>. In Indian apartment projects, loading of 25\u201340% is common, and it can be higher in projects with large amenities.<\/p>\n\n\n\n

A worked example<\/h2>\n\n\n\n

Suppose a flat is advertised at 1,300 sq ft super built-up<\/strong> for \u20b98,000 per sq ft<\/strong>, so the price is \u20b91.04 crore. The carpet area in the agreement is 950 sq ft<\/strong>.<\/p>\n\n\n\n

Measure<\/th>Value<\/th><\/tr><\/thead>
Advertised (super built-up) area<\/td>1,300 sq ft<\/td><\/tr>
Carpet area<\/td>950 sq ft<\/td><\/tr>
Loading<\/td>(1,300 \u2212 950) \u00f7 950 \u2248 37%<\/td><\/tr>
Price<\/td>\u20b91,04,00,000<\/td><\/tr>
Price per sq ft of super built-up<\/td>\u20b98,000<\/td><\/tr>
Price per sq ft of carpet area<\/strong><\/td>\u2248 \u20b910,950<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The second number is the one that tells you what you really pay for usable space. When you compare two projects, always compare price per sq ft of carpet area<\/strong>.<\/p>\n\n\n\n
