Enter your house construction budget and plot size below to instantly see the built-up area, number of floors, and finish level you can realistically afford — plus whether your room requirements (bedrooms, kitchen, parking, and more) comfortably fit within it.
Note: This tool estimates built-up area, room fit, and finish level only. Formal floor plans and architectural drawings are a separate step — see below.
Tell us your budget and requirements — we'll estimate what you can build
Your Project Brief Worksheet is free and automatic — this is a separate, optional next step
Delivered automatically to your inbox the moment you request it above — a one-page summary of your budget, plot, room requirements, and achievable area that you can hand to any architect or contractor of your choice.
Want our engineers to review your column grid options, span efficiency, and room-sizing trade-offs before you lock in a layout? This paid consultation is a separate step you can request whenever you're ready — it's the natural next step toward a full structural design engagement.

| Room | Typical range (sq ft) | Category | Notes |
|---|---|---|---|
| Master bedroom | 180–240 | Core | Shrinks last, and least, if the budget is tight |
| Standard/secondary bedroom | 120–160 | Core | Kids'/guest room |
| Living/hall | 200–320 | Core | Scales most with total BUA — smaller homes compress this first among core rooms |
| Kitchen | 80–120 | Core | Modular kitchen comfortably fits ~100–110 |
| Attached bathroom (per bedroom) | 35–45 | Core | One per bedroom by default |
| Utility/wash area | 30–50 | Semi-core | Shrinks to minimum before any core room does |
| Dining | 100–150 | Optional | First to merge into living if space is tight |
| Common/guest bathroom | 30–40 | Optional | First converted to a shared bathroom if space is tight |
| Balcony (per bedroom) | 40–60 | Optional | Reduced toward minimum, rarely removed entirely |
| Puja room | 15–25 | Optional | First room removed if space is tight |
| Foyer/entrance | 30–50 | Optional | — |
| Study/home office | 80–100 | Optional | Second room removed if space is tight |
| Servant/store room | 80–100 | Optional | Third room removed if space is tight |
| Staircase (per floor, internal) | 60–100 | Core (if applicable) | Only for G+1 and above |
| Covered car parking (per car) | 120–150 | Excluded from BUA | Usually counted separately from built-up area |
Plus a circulation/wall-thickness allowance of roughly 15–20% of built-up area, applied as a percentage overhead rather than a discrete room. If your room requirements don't comfortably fit, we trim optional rooms first (in the order shown above), then shrink semi-core and finally core rooms toward their minimum sizes — the master bedroom is the last thing we'd ever reduce.
These are reference benchmarks used to sanity-check your room requirements against your achievable built-up area — not a generated floor plan. Room positions, adjacency, and layout remain an architectural design step.
Common questions about planning a house construction budget in India
It depends on your budget, plot size, location, soil condition, and chosen finish level. As a rough guide, a standard-finish home in most Indian cities costs roughly ₹1,800–₹2,100 per sq ft of built-up area, so a ₹40 lakh budget typically supports around 1,900–2,200 sq ft at standard finish — before location/soil/floor adjustments. Use the calculator above for a figure based on your own numbers.
It works in reverse compared to a typical cost calculator — instead of asking "what will my project cost," you enter your available budget and it estimates the built-up area, floors, and finish quality you can realistically achieve, and whether your desired room count fits that area.
This depends on your plot size and achievable built-up area. A single floor typically uses 60–70% of the plot as ground coverage; if your achievable area exceeds what fits on one floor at that ratio, an additional floor is usually more cost-efficient than expanding the footprint further.
This tool provides a preliminary, ballpark planning estimate based on typical market rate ranges — not a final quotation. Actual achievable area and cost can vary ±20–40% depending on design complexity, material choices, and site-specific factors. For a project-specific figure, request a consultation.
