How to Calculate Built Up Area from Plot Area

In construction of a house there are many factors which are important. Especially when it comes to calculation and doing the math, you have to be precise. It is important to know about the carpet area, built up area, plot area, etc. If you are not aware of these details and want to know about what is built up area and plot area, and how to calculate built up area from plot area if you have just that much information, then you are at the right place. I am answering all these questions for you. Let us start by addressing what is built up area and what is plot area. 

What is Built up Area?

Built up area is the total floor area of a property which includes the sump of carpet area, are of walls and balcony area.

What is plot area?

Many people often get confused between built up area and plot area. But there is a significant difference between the two. Plot area is the total area of land you own which is enclosed by the boundary. 

How to find built up area from plot area?

To calculate built up area from plot area you must also have the floor area ratio which is fixed by the authorities to restrict the land height of the building. 

Let us know how to calculate built up area from plot area with the example below:

Assuming that the FAR is 1.5 in the locality where your property is and the plot area is 1000 sq ft. then the built up area according to the formula will be:

FAR = Total built up area / total plot area

FAR is 1.5, total plot area is 1000 sq ft., 

 

Therefore, built up area will be:

1.5 = Total Built up area / 1000

Total built up area = 1500 sq ft

I hope now you have an idea on how to calculate built up area to plot area.

Knowing the exact size of your property, including the plot area, BUA calculation is crucial. In simple words, if I say the plot area means the total land enclosed by the boundary. It is also called a site area, which is the piece of land owned by the client. Now, the built-up area is the total enclosed area within a building, including the carpet area (usable indoor space) plus walls, balconies, terraces, and any additional structures on the plot. Let me share the process of how you can calculate BUA below.

How to Calculate BUA?

Everyone here described about the BUA very well, so without going into detail here I am mentioning easy steps to calculate BUA:

• Identify Plot Area: Measure the total land area occupied by the structure, including exterior additions like sheds or carports.

• Determine Carpet Area: Calculate the usable indoor floor space within the walls.

• Add Wall Area: Calculate the area of the walls, usually 10-15% of the carpet area.

• Include Balcony and Terrace Areas: Measure balcony and terrace spaces. Add these to the carpet area for the total built-up area.

• Use FSI/FAR Rules: Floor Space Index (FSI) or Floor Area Ratio (FAR) regulates the permissible built-up area relative to the plot area, following local rules.

Here is the formula you can use to do BUA area calculation:

Built-Up Area = Carpet Area + Wall Area + Balcony Area + Terrace Area

Also, the built-up area is 15 to 30% more than the carpet area. Like for carpet area is 1,000 sq. ft, the built-up area is around ‌1150 to 1,300 sq. ft. I hope you found the answer helpful.

The difference between these two terminologies was explained very clearly from the above-mentioned 2 answers by Vijay and Soumya. Nevertheless, I would like to reiterate the same, 

Plot Area refers to the area that has a boundary (such as fencing) around it. The term "plot area" simply refers to the entire territory in a city or municipality that is yours. Plot area, often known as PA-1, PA-2, etc., is a phrase commonly used in townships and gated communities. They are helpful in determining a certain person's strategy.

However, the Build-up area is the term used to describe all of the building space on a site. Simply put, built-up area or plinth area refers to the area around a building that excludes unoccupied space, and the built up area formula is;

Built-Up Area = Carpet Area + All Wall Thickness + Balcony

I would like to conclude here about the built-up area and plot area meaning. I hope this helps:)

The required setback area for high-rise buildings is more. Plot area – Built-up area = Setback area How to calculate built-up area from plot area if you know the floor area ratio: Floor area ratio (FAR): It denotes the maximum floor space that can be built on a piece of land. It is a ratio between a building’s total constructed floor area and the land area. (Total built-up area/Total plot area) = FAR For instance, if the FAR for a building that you want to construct in your area is 3 and the plot area is 2000 square feet, then: The built-up area = 3 = Total built-up area / 2000 Total built-up area = 6000 square feet Avail NoBroker’s Legal Services if You Face Any Issue While Selling/Buying Property Read more: How to calculate plot area?
