House plans by plot size: what fits on 20×30 to 40×60, and what it costs
20×30, 25×40, 30×40, 30×50, 40×60 — India's five standard plot sizes, and every plan site sells them as static PDFs. Here each size gets what fits, G+1 built-up ranges, honest costs — and a button that opens the plan live in our free 3D designer. Drag it, walk through it, save it.

| 25 × 40 | 1,000 sqft | 2BHK + study | 1,100–1,400 sqft | ₹19.8–25.2 L | ₹33–42 L |
| 30 × 40 | 1,200 sqft | 3BHK + parking | 1,600–2,100 sqft | ₹28.8–37.8 L | ₹48–63 L |
| 30 × 50 | 1,500 sqft | 3–4BHK + parking | 2,000–2,600 sqft | ₹36–46.8 L | ₹60–78 L |

Method: net ground floor after setbacks ≈ 60–65% of the plot; G+1 ≈ 1.15–1.75× the plot area. Costs are our arithmetic from the 2026 rate card tiers, before finishing buffer. Your sanctioned plan fixes exact numbers.
20 × 30 — the compact starter (600 sqft)
Room for a compact 1BHK or a tight 2BHK G+1 with parking — keep the staircase compact and skip the deep porch. Small plots punish every wasted foot, so draw it first and cost it second.
Open the compact 1BHK plan →25 × 40 — the 2BHK sweet spot (1,000 sqft)
A proper 2BHK with study nook, garden patch and parking at 1,100–1,400 sqft G+1. The most forgiving small plot: rooms stay rectangular, Vastu zones fall naturally, and the budget stays under ₹25 lakh standard.
Open the 2BHK Vastu plan →30 × 40 — India's most-built plot (1,200 sqft)
The 3BHK G+1 at 1,600–2,100 sqft — kitchen SE, master SW, parking east. Two variants live in the designer: the courtyard 3BHK and the east-facing Vastu 3BHK (2,007 sqft, score 98/100), fully mapped in our east-facing 3BHK guide.
30 × 50 — room to breathe (1,500 sqft)
2,000–2,600 sqft G+1: a 4-bedroom duplex with family lounge, south lawn and covered parking — or a 3BHK plus a rentable first-floor unit, which changes the loan math entirely. Upper floors cost 30–40% less per sqft once the frame stands.
Open the 4BHK duplex plan →40 × 60 — villa territory (2,400 sqft)
3,200–4,200 sqft: a luxury villa or two stacked units with garden on three sides. At this size the plan deserves an architect's eye on orientation and levels — start from the duplex preset, stretch it, then send us the link for a free feasibility study.

Frequently asked questions
Which plot size is best for a 3BHK in Maharashtra?
30×40 (1,200 sqft) is the sweet spot — built G+1 it yields 1,600–2,100 sqft, room for a proper 3BHK with parking. On 25×40 a 3BHK is possible but cramped; below that, plan 2BHK or build an extra floor. Our east-facing 3BHK for 30×40 opens live in the designer.
What fits on a 20×30 plot?
600 sqft of land yields roughly 700–900 sqft G+1 — a compact 1BHK or tight 2BHK with parking. Keep rooms minimal, staircase compact, and avoid wasting frontage on a deep porch. Open the compact 1BHK plan in the designer to see the arrangement.
How is the built-up area estimated from plot size?
Method used on this page: net ground floor after setbacks is roughly 60–65% of the plot; G+1 roughly doubles that minus staircase and walls — about 1.15–1.75× the plot area depending on setbacks and floor count. Your sanctioned plan fixes the exact number; treat these as planning ranges.
What does a house on a 30×50 plot cost?
At 2,000–2,600 sqft G+1: roughly ₹36–47 lakh standard (₹1,800/sqft) or ₹60–78 lakh premium (₹3,000/sqft), plus finishing buffer. The full sourced rate card is in the 2026 construction cost guide.
Are these plans Vastu-compliant?
Each linked plan follows the standard zone map — kitchen south-east, master south-west, living north, pooja north-east (see the east-facing 3BHK guide for the full rules table). Open any plan and drag rooms to match your exact facing.
Can I get these plans modified for my exact plot?
Yes — open any plan below, drag blocks to your dimensions, save it to your account, and send us the link. We do a free feasibility study against your setbacks, soil and facing before quoting.
