About 42 x 45 House Plans
A 42 x 45 plot gives roughly 1890 sq ft of built-up area per floor and is one of the most-built plot sizes in India. On a 42 x 45 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 42 x 45 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 42 x 45 plot usually leaves a footprint of about 1,230 sq ft per floor. At 42 ft wide the plot takes a side garden or a two car porch, and a single floor 3 BHK becomes realistic; compare with villa and bungalow plans. The 45 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 42 x 45 house is about Rs 20 to 30 lakh and a G+1 about Rs 39 to 59 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 | 1,230 sq ft | 2 to 3 BHK | Rs 20 to 30 lakh |
| G+1 (duplex) | 2,460 sq ft | 3 to 4 BHK | Rs 39 to 59 lakh |
| G+2 | 3,690 sq ft | 4 to 5 BHK or owner + rental | Rs 59 to 89 lakh |
