How to Measure Proportionate Land of Your Apartment (Part 1)

When you buy an apartment, you don’t buy only the apartment but also buy the proportionate undivided and undemarkcated land for which you have to pay a significant amount. Also during the registration process, you have to register your apartment as well as your proportionate land. When buying we usually carefully check the apartment size and but one important aspect of apartment we neglect to check vigilantly is the proportionate land of the apartment.

Now let’s try to learn how to calculate the proportionate land for the apartment you wish to buy.

How to Measure Proportionate Land of Your Apartment

Proportionate  Land = {Total Land Area of the Project  / Total Construction Area (including Common Area} × Particular apartment area (including common area).

Proportionate land area depends on the apartment size of different floors.

Example-1 for Single Unit Apartment

Consider a project with

Land Area: 5 katha

Project story height:  G+8

Number of Apartments:  5

Apartment size 2120 sft in each floor

If you buy A-4 apartment, then what will be the proportionate land area for you?

8th Floor A-8, 2,120 sft
7th Floor A-7, 2,120 sft
6th Floor A-6, 2,120 sft
5th Floor A-5, 2,120 sft
4th Floor A-4, 2,120 sft
3rd Floor A-3, 2,120 sft
2nd Floor A-2, 2,120 sft
1st Floor A-1, 2,120 sft
Ground Floor



In the project, total construction area 2,120 sft × 8= 16,960 (all apartments are equal in size).

Total land area 5 katha.

A-4 apartment size is 2,120 sft

So, the Proportionate land area for A-4 apartment is

= (Total Land Area/ Total Construction Area) × A-4 apartment size

= (5 Katha / 16,960 sft) × 2,120 sft.

= 0.625 katha.

Example-2 for Double Unit Apartment

Land Area: 9 katha.

Total number of apartments: 16

Project story height:  G+8. Each floor has two type apartments. Type A 2,050 and Type B 2,150 sft.

Suppose you buy B 5 apartment, then what will be the proportionate land area?

                      Type-A               Type-B

8th Floor A-8, 2,050 B-8, 2,150
7th Floor A-7, 2,050 B-7, 2,150
6th Floor A-6, 2,050 B-6, 2,150
5th Floor A-5, 2,050 B-5, 2,150
4th Floor A-4, 2,050 B-4, 2,150
3rd Floor A-3, 2,050 B-3, 2,150
2nd Floor A-2, 2,050 B-2, 2,150
1st Floor A-1, 2,050 B-1, 2,150
Ground Floor



Total construction area is (A type 2,050 sft × 8)+ (B type 2,150 sft × 8) = 33,600 sft.

Total land area = 9 katha.

B-5 apartment size = 2,150 sft.

So, proportionate land size for Apartment B-5

= (Land Area 9 Katha/ Total Construction Area 33,600 sft )× 2,150 sft. B-5 apartment

= 0.5759 katha.

Example-3 for Mixed Size Apartment

Total land area: 13 katha

Number of apartments: 28

Project story height:  Basement + Ground floor + 9 Floors. Floor allocations are as follows. Now if you want to buy apartment D 9, let’s see how much your proportionate land will be.

10th Floor F-10, 1550 sft                   G-10, 3,600 sft
9th Floor                        D-9, 3,300 sft E-9, 1,850 sft
8th Floor A-8, 1,550 sft B-8, 1750 sft C-8, 1850 sft
7th Floor A-7, 1,550 sft B-7, 1750 sft C-7, 1850 sft
6th Floor A-6, 1,550 sft B-6, 1750 sft C-6, 1850 sft
5th Floor A-5, 1,550 sft B-5, 1750 sft C-5, 1850 sft
4th Floor A-4, 1,550 sft B-4, 1750 sft C-4, 1850 sft
3rd Floor A-3, 1,550 sft B-3, 1750 sft C-3, 1850 sft
2nd Floor A-2, 1,550 sft B-2, 1750 sft C-2, 1850 sft
1st Floor A-1, 1,550 sft B-1, 1750 sft C-1, 1850 sft
Ground Floor



Total construction area (1,550+1,750+1,850)*8+ 3,300 sft +1,850 sft+1,550 sft+3,600 sft = 51,500 sft.

D-9 apartment size is 3,300 sft.

Total land area = 13 katha.

So, proportionate land for D-9 apartment

= ( Total Land Area 13 Katha / Total Construction Area 51,500 sft) × D-9 apartment 3,300 sft.

= 0.833 katha.

With this you can ensure your proportionate land is just what you deserve. Since buying an apartment is a huge investment, make sure you have covered all fronts and there are no chances of remorse.
