About 15 x 18 House Plans
A 15 x 18 plot gives roughly 270 sq ft of built-up area per floor and is one of the most-built plot sizes in India. On a 15 x 18 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 15 x 18 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 15 x 18 plot usually leaves a footprint of about 230 sq ft per floor. At 15 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 18 ft depth is comfortable for two rooms deep plus a rear utility, with no internal courtyard needed on most facings.
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 15 x 18 house is about Rs 4 to 6 lakh and a G+1 about Rs 7 to 11 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 | 230 sq ft | 1 BHK | Rs 4 to 6 lakh |
| G+1 (duplex) | 460 sq ft | 1 BHK | Rs 7 to 11 lakh |
| G+2 | 690 sq ft | 2 BHK or owner + rental | Rs 11 to 17 lakh |
