A Comprehensive Explanation of Carpet Area, Built Up Area/ Plinth Area and Super Built Up Area


Planning to buy a property? Well, it is essential that you have a clear understanding of what are Carpet Area, Built up Area, Plinth Area and Super Built Up Area.

Carpet Area, Built Up Area/ Plinth Area and Super Built Up Area is a puzzle for most home buyers. Almost everyone who has purchased a property or about to purchase one are worried about how to calculate the area. Generally, the explanations available on the internet add to the puzzle. The fact is that there are no read standard guidelines available for Indian real estate industry. Pointless to state, most developers take advantage of this information crack.


Let me give you the most logical definitions and analysis on the subject, so that you are much more self-assured when you go property searching next time.


What is Carpet Area?

As the name suggests, carpet area refers to the area of the property where you can lay your carpet (wall to wall measurement). This is the actual area which you may claim as your personal space. This is the area you should be actually concerned about.

Areas incorporated in Carpet Area

  • All Rooms – Living Room, Dining Room, Bedrooms, Dressing Room, other rooms.
  • Kitchen
  • Bathrooms
  • Stores
  • Balconies
Areas not a part of Carpet Area
  • External and Internal walls
  • Common Areas
It is important to keep in mind that balconies are included in carpet area calculation but terraces (if any attached to a unit) are usually sold independently at a lower per sqft rate. The reason being terraces are not included in FSI calculation (Floor Space Index) also known as Floor Area Ratio of the developer.

Once you ask, the marketing staff may say that they are offering the highest carpet area ratio and are just using a loading factor of 25%. He will show you the carpet area calculation as follows:


Carpet Area = 1500 * (100-25)%  = 1125 sqft,
this is a wrong method to work out the carpet area.


The correct method for carpet area calculation

 
Carpet area * 1.25 = Saleable Area
Carpet Area = Saleable area / 1.25 = 1500 sqft / 1.25 = 1200 sqft.

You should have got 1200 sqft with 25% loading.
Keep in mind that the loading factor is supposed to be loaded (added) and not subtracted.


Conversely, if the real carpet area is 1125 sqft (can be calculated from the layout in brochure), the super built up area should be 1125 * 1.25 = 1406.25 for which you are expected to pay, while the builder may charge you for 1500 sqft. i.e. for 93.75 sqft. extra.
 

What is Plinth Area / Built Up Area?

This is the gross area of a flat. Above and beyond the carpet area, it includes the space covered by the wall thickness and ducts. Normally, it is 10-15 per cent more than the carpet area of the flat. As a rule of thumb, built up area can be computed by adding 10% loading factor on carpet area. This is however, not so essential while buying a property as nearly all developers sell the property on super built up area. Nevertheless, this term becomes imperative while dealing with government departments as in many states; property taxes are levied on built up area/ plinth area.

Areas included in Plinth Area / Built Up Area

  • Whole carpet area
  • Internal and External Walls
  • Utility Ducts within walls of the unit
Areas not a part of Built Up Area/ Plinth Area 
  • Common Areas

What is Super Built Up Area?

Super Built up Area refers to the built up area added to common areas proportioned to a unit. The super built up area can be calculated by adding a loading factor to the carpet area, which could fluctuate from 15% to 50%. The lower the factor the better it is for you as a customer. You get a higher carpet area for the same amount.  You should pay most attention to areas included in Super Built Up Area and Entire Built Up Area.

Common Areas – lobby, staircases, lift ducts, air ducts, pipe ducts/ shafts, clubs, covered community centres and other covered common facilities.


Areas generally not to be included in Super Built Up Area


  • Open Areas like parks, gardens, play areas etc.
  • Roof Terrace
At times, Super Built Up Area is also called as usable area, saleable area or just super area.
