Direction: A plot of land is to be developed as a residential neighborhood. The key development conditions and project requirements are given below
Plot area: 1.25 Hectares
Maximum pemissible ground coverage: 30%
Density of population: 800 ppHa
Maximum pemissible FAR: 350
Maximum permissible height: 45 m
Average household size: 3.55 
-
The total number of dwelling units under L.I.G., M.I.G. and H.I.G. respectively are
-
- P
- S
- Q
- R
Correct Option: C
The question is not well-specified. C seems to be the closest answer.
Density of Population = 800 ppH (Assuming it to be Residential-density of Dwelling Units)
Plot Area = 1.25 hectares
Average household Size = 3.55
Let n be the no. of Dwelling Units Net area of Dwelling Units
Total built up of all units = 4480 + 18600 + 14200
= 37280 sq m = 3.7 hectares
FAR × Total Plot Area of D.U = Total Built-up
3.50 × Total Plot Area of D.U = 37,280 sq m
Total Plot Area of D.U = 37,280/3.50 = 10651 sq m = 1.065 hectares
Density = Total Population /Total Area
Density = No. of Dwelling Units × Avg Household size/Total Area under Dwelling units
880 = (n × 3.55)/1.065 DU = 264
Total no. of Dwelling units as 264 for further calculations,
