1 BHK, 2 BHK and 3 BHK sizes, and how many fit on your floor
Before you talk to a builder, it helps to know how big each type of home usually is and how many fit on one floor of your plot. Sizes below are typical built-up areas in Hyderabad; your architect will refine them.

|---|---|---|
| 1 RK | 300 – 400 sq ft | ~350 sq ft |
| 1 BHK | 500 – 650 sq ft | ~600 sq ft |
| 2 BHK | 900 – 1,100 sq ft | ~1,000 sq ft |
| 2.5 BHK | 1,100 – 1,300 sq ft | ~1,200 sq ft |
| 3 BHK | 1,300 – 1,600 sq ft | ~1,450 sq ft |
| 4 BHK | 1,800 – 2,400 sq ft | ~2,000 sq ft |
How many units fit on one floor?
Using the buildable area per floor from the planner (Stilt + 2 floors, 30–40 ft road) and keeping about 150 sq ft for the staircase and lift:
| Plot (ft) | Buildable / floor | What fits on one floor |
|---|---|---|
| 30 × 40 | 745 sq ft | 1 × 1 BHK |
| 30 × 50 | 980 sq ft | 1 × 1 BHK |
| 40 × 50 | 1,398 sq ft | 2 × 1 BHK |
| 40 × 60 | 1,677 sq ft | 1 × 3 BHK · 1 × 2 BHK + 1 × 1 BHK · 2 × 1 BHK |
| 50 × 80 | 2,488 sq ft | 2 × 2 BHK · 1 × 3 BHK · 1 × 2 BHK + 1 × 1 BHK |
| 60 × 90 | 2,994 sq ft | 2 × 2 BHK · 1 × 3 BHK · 1 × 2 BHK + 1 × 1 BHK |
Plan it floor by floor
In the planner's Floor-by-floor table, open any floor with the small arrow, add units (1 BHK to 5 BHK, shops, offices, washrooms, a home theatre and many more), set their sizes, and see at once how much space is left or over. You can also set your own floor area, for example 1,450 sq ft agreed with the customer, and plan against it.
