Built up Area vs Carpet Area vs Super Built-up Area: Differences

Built up area vs carpet area – The numbers that are presented to you when purchasing a home can be perplexing. After starting with a 1,200-square-foot house, you discover that only 850 of it is truly usable. What became of the others? What happened to those extra square feet? Is there a secret room they’re hiding in that you were unaware of?

Nope—that’s where concepts like super built-up area, built up area vs carpet area, and carpet area are useful. However, knowing these terms has a direct impact on how much space you get, how much you end up paying, and whether your ideal sofa will fit in the living room (or end up wedged between two walls).

It’s not just about looking smart in front of your broker. It has a direct effect on the amount of space you receive, the cost, and whether you’ll have enough room for the sofa of your dreams. For you to make wise decisions, let’s simplify it. 

Why Should You Care About These Measurements?

You would expect 1,200 square feet of livable space if you were paying for 1,200 square feet, wouldn’t you? Not exactly. Due to various measurement methods, the actual space you use is frequently much smaller than what is advertised. This is why these terms are important:

1. Pricing: The super built-up area, which includes common areas, is frequently used by builders to determine the price of homes. Your cost per square foot may be higher than you anticipate, though, because you’re living in the carpet area.

2. Space Planning: Knowing how much real space you’ll have will help you decide whether a certain house is right for you, where to put furniture, and whether to make renovations.

3. Comparing Properties: Although both apartments may have 1,500 square feet listed, one may have more carpet space and the other may have a lot of common space. You can make a fair comparison if you are aware of these figures.

4. Transparency: The Real Estate Regulation and Development Act, or RERA, has made it mandatory for builders to reveal the carpet area. To make houses appear larger, some people still attempt to draw attention to areas that are extremely populated. You can identify these strategies more easily if you know the difference.

Now that you understand the significance of these figures, let’s examine each one separately.

What is Carpet Area?

Your home’s carpet area is the actual usable space where you can lay carpet. This is where you will live because it does not include walls, balconies, or common areas.

Included in the Carpet Area is:

• Living room, kitchen, dining room, and bedrooms

• Toilets and areas for utilities

• If your unit has internal staircases

Not Included in the Carpet Area:

• Internal wall thickness

• Terracces and Balconies

• Common places, such as elevators, stairwells, and lobbies

How to Calculate Carpet Area?

Carpet area is calculated using the formula:

Carpet Area = Sum of all usable room areas

Example: If your apartment has the following room sizes:

• Living Room: 300 sq. ft.
• Bedroom 1: 200 sq. ft.
• Bedroom 2: 180 sq. ft.
• Kitchen: 120 sq. ft.
• Bathrooms: 50 sq. ft.

Total Carpet Area = 300 + 200 + 180 + 120 + 50 = 850 sq. ft.

To give buyers total transparency, developers are now obligated by the Real Estate Regulation and Development Act (ERA) to reveal the precise carpet area of a unit.

The Significance of Carpet Area

The amount of carpet area is important because it affects the amount of real space in your house. Because it explains exactly what you’re getting for your money, it’s the most helpful metric for buyers.

What is a Built-up Area?

The carpet area as well as the thickness of the exterior and interior walls make up the built-up area. It also takes terraces, balconies, and occasionally duct spaces into account.

The Built-up Area consists of:

• Carpet Area

• Both exterior and interior walls

• Terraces and balconies

Excluded from Built-up Area:

• Common or shared spaces (corridors, lobbies, etc.)

• Features such as gardens and clubhouses

How to Calculate Built-up Area?

Built-up area is typically 10-20% more than the carpet area, using the formula:

Built-up Area = Carpet Area + Walls + Balconies

Example: If the carpet area is 850 sq. ft., and the walls and balconies occupy 15% extra space:

Built-up Area = 850 + (15% of 850) = 850 + 127.5 = 978 sq. ft. (approx.)

Builders may mention built-up areas instead of carpet areas to make properties seem larger than they are.

Built up Area vs Carpet Area

Typically, the carpet area is 10–20% smaller than the built-up area. For instance, the built-up area maybe 1,150 square feet if the carpet area is 1,000 square feet. Walls and balconies are included in this additional space, but communal areas with neighbours are not. 

What is Super Built up Area?

Let’s move on to the highly developed area, also referred to as the saleable area. This comprises all of the built-up area as well as a fair portion of common spaces like elevators, lobbies, stairways, and amenities. Super built up area meaning includes these shared spaces, which are proportionately divided among all apartment owners.

The Super Built-up Area consists of:

• Area built up (carpet, walls, and balconies)

• Common spaces (corridors, elevators, stairways, and lobbies)
  
• Clubhouses, gyms, and occasionally swimming pools are examples of amenities.

Excluded from the Super Built-up Area:

• Your assigned parking spot, which is typically offered for sale separately

• The building’s surroundings are open green areas.

How to Calculate Super Built-up Area?

Super built-up area is calculated using the formula:

Super Built-up Area = Built-up Area + Proportionate Share of Common Areas

Example: If the built-up area is 978 sq. ft., and the proportionate share of common areas is 30% of the built-up area:

Super Built-up Area = 978 + (30% of 978) = 978 + 293.4 = 1,271 sq. ft. (approx.)

Builders may inflate this number, so it’s essential to compare it with the actual carpet area.

Super Built up Area vs Carpet Area

This is the difficult part. The actual carpet area may be significantly smaller—sometimes as little as 1,000 square feet—than the developer’s stated 1,500 square feet of super built-up area. Before making a purchase, it is crucial to request a detailed breakdown of the carpet area.

Other Important Factors to Consider

Loading Factor

The ratio of the super built-up area to the carpet area is known as the loading factor. A project with a loading factor of 40% indicates that common areas make up 40% of the super built-up area. You will have less actual living space if the loading factor is higher. 

Formula:

Loading Factor = (Super Built-up Area – Carpet Area) / Carpet Area × 100

Example:

If Super Built-up Area = 1,271 sq. ft. and Carpet Area = 850 sq. ft.:

Loading Factor = (1,271 – 850) / 850 × 100 = 49.53%

Regulatory Guidelines (RERA Compliance)

Before RERA, builders frequently marketed properties in highly populated areas, which confused buyers. To ensure greater transparency, developers are now required to specify the carpet area in all sales agreements. 

Hidden Costs Associated with Built-up and Super Built-up Areas

Most purchasers concentrate on a home’s price per square foot. However, have you thought about the unstated expenses associated with densely populated and highly densely populated areas?

Increased Upkeep Expenses

A high loading factor results in higher maintenance costs because these fees are frequently assessed per super built-up area.

You will still be responsible for maintaining the common areas even if you don’t use them.

A higher property tax

Your tax bill may increase because property taxes are sometimes calculated using the built-up or super built-up area rather than the carpet area. 

Less Space Available for Use for Each Rupee Spent

You only get 60% of the actual usable space you pay for if an apartment has 40% loading.

You will pay more per square foot of usable space even though builders may offer “affordable rates” with higher loading.

Common Myths About Carpet, Built-up & Super Built-up Area

Myth #1: A larger home is associated with a higher super built-up area  

In actuality, it simply means that you are paying for more shared areas. For real usable space, look at the carpeted area.

Myth #2: The best indicator of a home’s size is its built-up area 

Wall thickness is included in a built-up area, which makes it a little deceptive. The most accurate measurement is the carpet area.

Myth #3: The loading factors of every project in the same city are the same  

The truth is that while low-cost apartments make the most of the carpet area, luxury projects typically have higher loading factors.

Myth #4: Super built-up area confusion was eliminated by RERA 

Although RERA requires the disclosure of carpet areas, many builders continue to use super built-up areas in their marketing to give the impression that their projects are larger.

Wrapping Up

You can’t ask for more space later when you buy a home, so it’s not like ordering extra fries! Despite the fancy numbers on the sales pitch, once you buy, you’re stuck with the actual livable area. And believe us when we say that moving furniture won’t magically make more space.

Therefore, put the carpet area first before committing and ignore the hype surrounding the highly built-up area. Examine efficiency ratios, compare projects, and avoid being duped by exaggerated figures. Make sure every square foot you’re paying for is beneficial to you, ask for floor plans, and inquire about the loading factor. Understanding built-up area vs. carpet area can help you make a smarter choice.

After all, how large your home feels when you live there matters more than how large it sounds. Since you’re ultimately purchasing a place to call home rather than a number.
