About 20 x 100 House Plans
A 20 x 100 plot gives roughly 2000 sq ft of built-up area per floor and is one of the most-built plot sizes in India. On a 20 x 100 plot you can plan anything from a compact single-floor home to a spacious multi-floor house, depending on your family size and budget. Every 20 x 100 plan below can be customised for your exact plot and made Vastu-compliant, complete with floor plan, elevation, 3D visualization, Vastu and working drawings under one roof. Explore all our projects or book a free consultation to start your home.
Most municipal bylaws take 1 to 3 m at the front and 1 to 1.5 m at the rear, so a 20 x 100 plot usually leaves a footprint of about 1,700 sq ft per floor. At 20 ft wide, the staircase has to run along a side wall and the plan works best as a G+1 or G+2; see our narrow plot house plans. The 100 ft depth means the middle rooms need a courtyard or light well, or they go dark; read natural light and ventilation in house design.
Cost in 2026 at a standard finish runs Rs 1,600 to 2,400 per sq ft of built-up area, so a ground floor only 20 x 100 house is about Rs 27 to 41 lakh and a G+1 about Rs 54 to 82 lakh, excluding land, approvals and interiors. Run your own numbers in the construction cost calculator, and if you are deciding between one and two floors read duplex vs single storey.
| Option | Built-up area | What fits | 2026 cost, standard finish |
|---|---|---|---|
| Ground floor only | 1,700 sq ft | 3 BHK | Rs 27 to 41 lakh |
| G+1 (duplex) | 3,400 sq ft | 4 to 5 BHK | Rs 54 to 82 lakh |
| G+2 | 5,100 sq ft | 4 to 5 BHK or owner + rental | Rs 82 to 122 lakh |
