Correct Answer - Option 2 : 50 % - 65 %
The carpet area of residential building may be 50 % to 65 % of the plinth area of building with a target of 65 %.
Carpet area of building is the useful area or liveable area or lettable area. This is the total floor area minus the circulation area, verandahs, corridors, passages, staircase, lifts, entrance hall, etc. and minus other non-usable areas as sanitary accommodations (bath and W.Cs.), air conditioning room etc.
For office building carpet area is the useable area and for residential building carpet area is the liveable area and should exclude the kitchen, pantry, stores, and similar other room which are not used for living purposes.
The carpet area of a building for any storey shall be the floor area excluding the following:
(a) Sanitary accommodation, (b) verandahs, (c) corridors and passages, (d) kitchen and pantries, (e) stores in domestic buildings, (f) entrance hall and porches, (g) stair cases and mumties, (h) shafts for lifts, (i) barsaties, (j) garages, (k) canteens, (l) air conditioning ducts and air conditioning plant room.
The carpet area of an office building may be 60 % to 75 % of plinth area of the building with a target of 75 %.
The planners should aim to achieve a target to 75 % of the plinth area. The carpet area of residential building may be 50 % to 65 % of the plinth area of building with a target of 65 %.
