When you're thinking of buying a house or an apartment, you will often hear terms like Carpet Area, Built-Up Area, and Super Built-Up Area. These are measurements that tell you how much space is in a property, but they can be confusing. Knowing what these terms mean can help you understand how much space you’re actually getting and how much you need to pay for it.
In this blog, we will explain these terms in simple words and help you understand their differences. By the end, you’ll know what each term means and how to use them when buying a home.
What Is Carpet Area, Built-Up Area, and Super Built-Up Area?
These terms are used to measure the space inside a property. Here’s what each one means:
Carpet Area Explained
Carpet Area is the actual space inside your home where you can walk around and place your furniture. It is the usable area that you can use to live in. The Carpet Area does not include the walls of the building, balconies, or other areas that cannot be used for daily living.
For example, if your apartment is 1,000 square feet, after removing the space taken up by the walls and balconies, the Carpet Area could be 800 square feet. This 800 square feet is the actual area you can live in.
Built-Up Area Explained
The Built-Up Area is a little bigger than the Carpet Area. It includes the Carpet Area, plus the space taken up by the thickness of the walls and other things like balconies or utility areas.
So, if your Carpet Area is 800 square feet, and the walls and other structural parts take up about 200 square feet, then your Built-Up Area would be 1,000 square feet. Built-Up Area tells you the total space that the property occupies, including walls and attached areas.
Super Built-Up Area Explained
The Super Built-Up Area is the biggest of the three measurements. It includes the Built-Up Area plus a share of the common areas in a building, such as the lobby, stairs, lift, and hallways.
If your Built-Up Area is 1,000 square feet and the shared areas (such as the lobby or lift) take up 500 square feet, then the Super Built-Up Area of your apartment will be 1,500 square feet. This gives you an idea of the total area you’re paying for, including not just your private apartment, but also the shared spaces in the building.
Key Differences Between Carpet Area, Built-Up Area, and Super Built-Up Area
Let’s take a look at how these terms are different:
1. Definition and Measurement
- Carpet Area: This is the actual usable space inside the apartment, excluding walls and balconies. It’s the space you can use for your furniture and day-to-day activities.
- Built-Up Area: This includes the Carpet Area plus the thickness of the walls and other things like balconies. It tells you the total space your property takes up.
- Super Built-Up Area: This includes the Built-Up Area plus a share of the common areas like lifts, corridors, and lobbies that you share with other residents in the building.
2. Purpose and Usage
- Carpet Area: This tells you how much actual space you can use for living. If you are thinking about how much room you have for your furniture, this is the area to focus on.
- Built-Up Area: This is useful for understanding the total space that the property occupies, including walls and other structural parts.
- Super Built-Up Area: This is used to show the total space you’re paying for, which includes your private space and the shared spaces like lifts and corridors.
3. Impact on Pricing
- Carpet Area: The price of the property is often directly related to the Carpet Area. The larger the Carpet Area, the more space you get for your money.
- Built-Up Area: Since this includes walls and other parts, it can affect the total cost of the property.
- Super Built-Up Area: This measurement has the biggest impact on the cost because it includes the shared spaces. Developers may use the Super Built-Up Area to show a larger size of the property, which could result in a higher price.
4. Market Trends
In India, especially in cities like Mumbai, Delhi, and Bangalore, developers often use the Super Built-Up Area to advertise properties. This is because it looks like a bigger space, but it includes shared areas that you don’t actually live in. So, you might be paying for space that you don’t fully use.
- Super Built-Up Area is commonly used in ads, but it includes areas you share with others in the building, so it’s not always the best measurement if you care about actual living space.
- Built-Up Area is more useful if you want to know how much of the space is privately yours, including the walls and structural parts.
- Carpet Area is the most important measurement if you want to focus on how much usable living space you have in your apartment.
5. Legal and Regulatory Aspects
- Carpet Area: This is the measurement often used in legal documents, such as agreements, because it shows the exact usable space.
- Built-Up Area: Although it’s not often mentioned in legal documents, the Built-Up Area is useful for understanding the overall size of your property, including structural parts like walls.
- Super Built-Up Area: This is more commonly used by builders for sales and marketing purposes to show the total space, but make sure you understand what’s included before buying.
Important Considerations for Property Buyers
If you are buying a property, here are a few things to remember:
- Check the Measurements: Always confirm the Carpet Area, Built-Up Area, and Super Built-Up Area with the seller or builder. Make sure you understand what each measurement means.
- Consider Common Areas: Make sure you know how much space in the building is shared with other residents, like the lobby or lift. These shared spaces are included in the Super Built-Up Area.
- Use Carpet Area for Furniture: If you're planning where to put your furniture or how much space you will have for daily living, focus on the Carpet Area.
Common Misconceptions About These Terms
Many people have some wrong ideas about these area terms. Here are a few:
- Misconception 1: Some people think that Super Built-Up Area is the same as Carpet Area. But Super Built-Up Area includes shared spaces, so it is always larger.
- Misconception 2: Some buyers think Carpet Area includes the walls, but it only refers to the actual usable space inside the walls.
- Misconception 3: Not all developers use these terms the same way. So, always ask for clarification and make sure you know exactly what each term means when you’re buying property.
Conclusion
Understanding the difference between Carpet Area, Built-Up Area, and Super Built-Up Area can help you make better decisions when buying or renting a home. Carpet Area is the usable living space, Built-Up Area includes walls and other structural parts, and Super Built-Up Area includes both your private space and shared spaces in the building.
