A four-story building with equal areas in each floor is required to be designed on a plot with FAR of 2.0. If the FAR is increased to 2.2, the percentage increase in ground coverage utilizing full FAR in both cases will be ___________
-
- 15 to 20
- 25 to 30
- 5 to 10
- 35 to 40
Correct Option: C
5 to 10
Let area be 100 units.
FAR = 2
Which means, Built up area = 2 × 100 = 200 units.
As each floor has equal area, so each floor area = 200/4 = 50 units.
So, ground coverage will be 50 m².
In second case,
site area = 100 units.
Therefore, Built up area = 220 units as FAR = 2.2
Ground coverage = 220/4 = 55
So ground coverage is increased from 50 to 55.
| Therefore, change in% = | × 100 = 10% | |
| 50 |
