20 × 30 house plan — what actually fits
600 sq ft of land. After a 5 ft setback all round you have about 200 sq ft to build on, which is tight for a full house at the standard we draw to.
The arithmetic
| Your plot | 20 × 30 ft = 600 sq ft |
|---|---|
| Setback, all four sides | 5 ft |
| Buildable rectangle | 10 × 20 ft = 200 sq ft |
| A comfortable footprint | about 200 sq ft — 33% site cover, garden on every side |
Setbacks vary by local rule and with building height. 5 ft is a modest figure used here for the arithmetic; confirm yours with the local authority before you rely on it.
How many bedrooms fit
At 914 mm clear each side of every bed and a 914 mm corridor — with a real kitchen, a living space and a covered entrance, not just bedrooms:
| Bedrooms | Needs about | On your plot |
|---|---|---|
| Two | 712 sq ft | not on one floor |
| Three | 807 sq ft | not on one floor |
On a plot this size, more rooms means a second storey rather than smaller rooms. Decide that now, not later — a future upper floor changes the setbacks you are allowed and puts a stair footprint in the ground floor plan today.
What we would check before drawing anything
- Which edge touches the road. It fixes the gate, the drive and the parking.
- Where the septic tank can go. 18 m from any borewell — IS 2470 and most state rules. On a small plot this eats a corner, so it gets placed before the house.
- Who lives there. Anyone elderly means a ground-floor bedroom near a W.C. and a step-free path from the gate.
- Two openings per habitable room, on two different faces. One window is not ventilation.
