Understanding the intricacies of real estate terms such as carpet area and built-up area is essential when navigating property purchases. These terms play a critical role in determining the actual space you will own and utilize. Lets delve deeper into each concept to empower you with comprehensive knowledge for informed decision-making.

UNDIVIDED SHARE OF LAND (UDS)

When you purchase an apartment, UDS (Undivided Share of Land) refers to your ownership stake in the land on which the entire building stands. For instance, if an apartment complex occupies 10,000 sq. ft. of land with 10 units, your UDS would amount to 1,000 sq. ft. (representing 10% of the total area). This share becomes crucial in scenarios such as redevelopment and significantly influences property resale value.

CARPET AREA

Carpet Area denotes the actual usable space within the walls of the apartment, where you can lay a carpet. It excludes the thickness of inner walls but encompasses areas like bedrooms, living rooms, kitchens, and bathrooms.

Formula: Carpet Area = Total Built-Up Area - thickness of inner walls

For example, if the total built-up area of your apartment is 1,000 sq. ft. and the wall thickness measures 100 sq. ft., the carpet area would be 900 sq. ft. This measurement holds significant importance as it represents the practical living space mandated by the Real Estate (Regulation and Development) Act, 2016 (RERA).

BUILT-UP AREA

Built-Up Area encompasses the carpet area along with the space occupied by walls and balconies. It provides a comprehensive view of the total area within the apartment boundaries.

Formula: Built-Up Area = Carpet Area + thickness of inner walls + area of balcony

Continuing the example, if the carpet area is 900 sq. ft., and the walls and balcony occupy an additional 150 sq. ft., the built-up area would total 1,050 sq. ft. This calculation helps you understand the complete spatial layout of the property.

SUPER BUILT-UP AREA

Super Built-Up Area includes the built-up area plus a proportional share of common areas such as lobbies, lifts, and amenities like gyms and clubhouses. This figure is often quoted by developers as the saleable area.

Formula: Super Built-Up Area = Built-Up Area + (Percentage of Common Areas × Built-Up Area)

Common areas typically range from 25% to 30%. For instance, if the built-up area of your apartment is 1,050 sq. ft., and the proportional share of common areas is 150 sq. ft., the super built-up area would total 1,200 sq. ft. Developers use this metric to price apartments, emphasizing the importance
of understanding the actual usable space you're investing in.

Mastering these terms—UDS, Carpet Area, Built-Up Area, and Super Built-Up Area—empowers you to make well-informed decisions when buying property. It ensures transparency and helps avoid misunderstandings regarding the space you'll own. Always inquire about these areas from developers to ensure your investment aligns with your expectations.

Remember: Efficiency ratio (Carpet Area/Super Built-Up Area) is key. A higher ratio indicates better space utilization. Take the time to gather detailed information before investing, safeguarding your investment in Chennai's competitive real estate market.
