When you purchase a new flat or when you need to sell your old house, you may have to calculate the total area of the flat. For that reason, we have come up with a few measuring techniques and formulas which can help you to measure the flat while buying property without an Engineer.
Most of the time, the investor is deceived in terms of the space, length, and width of the wall. To avoid such incidents, it is very crucial for a good experience that the investor himself check out the whole flat and compares it with the booklet by finding the appropriate dimensions.
First and foremost, you need to understand the three following aspects when you measure the area of the flat. Carpet area, built-up area, and the super built-up area.
What is the Carpet Area of the flat?
Carpet area is the exact area that can easily be covered by a carpet within a flat and it excludes the thickness of the internal walls. If you had to lay out a wall-to-wall carpet in your entire flat, the area covered would be the actual carpet area. It is the real area you get to use in your house.
Let’s discuss the Carpet area and why it is essential to keep in mind while buying the property. When you step out to buy a property in India, there is a lot of confusion about how carpet area is measured and How it differs from the Built-up area and Super Built-up area, etc.
By following the methods listed below will assist you to find out the actual layout area of the flat that you want to purchase. The calculated number will provide you an idea of the actual space that won’t be utilized. Thus, it is measured as wall to wall which means that the thickness of the wall is not involved in the carpet area. So, make sure to calculate the carpet area before buying a property as the carpet area is usually 70% of the total built-up area.
What Carpet area covers:
- Rooms- Bedrooms, Dining room, Study Room, Dressing Rooms and Other Rooms Bathroom
- Balconies within Property unit
- A staircase within the flat
What carpet area does not cover:
- External and Internal Walls
- Common areas
- Utility Ducts & Interior Part
How to Calculate Carpet Area?
Here’s the method to calculate the carpet area:
Carpet area = Sum of all Area (Bedroom + Balconies + living room + Toilets) — the thickness of
the internal walls The carpet area is normally around 70% – 75% of the built-up area. For example, let’s imagine that the built-up area is 2,000 sq ft then your carpet area should be around 1400 -1500 sq ft. You will have to practically measure the dimension of flat from wall to wall to get the actual
What is the Built-Up area?
The built-up area is the area that is taken by inner and outer walls and it also consists of ducts Interior part. It is also considered as the total covered area of the apartment and is the sum of carpet area, the area covered by the thickness of walls, and includes the terrace, balcony, and other livable areas.
What built up Area covers:
· External & Internal walls
· Carpet Area
· Utility Ducts & Interior part(sewage/water pipeline, Interior part of Door and window AC ducts and shafts, etc)
There is also a term which most of us are not aware of, that is lenvth/covered Area
The covered area does not contain a balcony and any structure called a cantilever. This does not have any kind of ground support or from the lower apartment. This, however, is covered in the Built-up area. So, the covered area/plinth area is the area under the Roof.
How do we calculate the Built-up Area?
Generally, the built-up area is 10% – 15% more than the Carpet area.
Carpet Area + Area of walls + Area of Utility & Interior part = Built Up Area
For Example: If the Carpet area is 500 sq.ft then the built-up area would be around 550 Sq Ft.
What is the Super Built-Up Area?
The built-up area of a property and the sum of common areas that are proportioned to the unit is called the Super built-up Area. The super built-up areas may include an elevator, swimming pools, garden, lobby, lifts, etc. But, parking does not count and it is charged separately. What covered by the super built-up area :
· Common areas — Clubhouses, Air ducts, Pipe/shafts Duct, Lift, Staircases, Lobby, Swimming
pool, Gymnasium (proportioned to the housing unit)
· Built-up area of the Property.
What it does not cover:
· Roof Terrace
· water tank
· Parks, Driveways, Garden, Play hub
How can we measure the Super built-up Area?
Super built-up Area = Built-up Area + Proportionate Common area
Firstly, you need to know about the total common area. For example, if the common area of 10 apartments is 200 sq.ft, then the area proportional to one housing unit would be a total common area divided by the Number of apartments = 200 sq.ft per apartment. If you don’t know the measurement of the Common area then here is a simple way to calculate it:
You can check the loading factor from the builder and calculate the super built-up area by adding the loading factor to the Carpet area. The loading factor may vary from 15 to 50% depending on the place of property and may vary from builder to builder.
Super Built up Area = Carpet Area(1+loading factor)
For Carpet Area = 2,000 Sq Ft
Super Built up Area = 2000 sq.ft(1+0.35) = 2700 sq.ft
How to calculate the square footage of an entire home
While measuring a single room is no big deal, people get kind of intimidated when it comes to calculating the square footage of an entire home. While homes can initially seem “daunting to measure, they're just a collection of small boxes. Don't sweat it if a room has an utcropping.
Simply break that area down into a smaller box, and measure each box individually. Add up each box's square footage to get the room's total area. So if your living room, bedroom, bathroom, and hallway are 500, 400, 200, and 100 square feet respectively, that means the total is 500 + 400 + 200 + 100 = 1,200 square feet total.
We have another formula of calculations:
Suppose, I am selling 1000 sqft super built-up area, then the built-up area will be 25% (750) sqft less of super built-up area and 30% (700) sqft for lift and complex projects. The carpet area will be 15% (638) sqft less of the Built-up area and 17% for lift and complex projects or straight 42% less from super built-up area and 47% for lift and complex projects. Difference between carpet area, built-up area, and super built-up area
It is the precise area within the walls where a carpet can be spread. It means the area is calculated from the inner wall to wall distance inside the house. And it is nothing but the net usable area inside the house.
Carpet Area + Area of ducts and walls + 1/2 the Area of the terrace
Super Built-up area:
Built-up area + area occupied by amenities like lifts, elevator, the veranda, swimming pools, garden, clubhouse, Staircase, lobby, lifts stairs (proportioned to the housing unit).
So, the conclusion here is that whenever you are going to buy a property keep carpet area, built-up area, super built-up area, and carpet area calculator in mind to make a good purchase. Pay for the area which you are going to use according to the measurements of the apartment or commercial property you’ll buy.
