About this 40×40 ft plot

A 40 × 40 ft plot gives you 1600 sqft of total area and roughly 1280 sqft of buildable footprint after standard setbacks. The aspect ratio is 1.00:1 deep, which is medium for a 3 BHK home. The engine's placement priorities adapt to this shape — wider plots favour social-zone width, deeper plots favour private-zone depth.

Frequently asked questions

What is the Vastu score for this 40x40 southwest-facing layout?+
This specific layout scored 74/100 — Good band. The engine attempts to place master bedroom, kitchen and puja in their classical Vastu zones where the buildable rectangle and circulation rules allow. Each room is also individually scored across solar, thermal, ventilation, daylight, magnetic alignment, pada and element factors. Vastu band on your personalised plan will depend on your exact plot, facing bearing, BHK, and any open-side or party-wall constraints.
What is the carpet area and built-up area for this plan?+
Carpet area is approximately 992 sqft. Built-up area (including walls and columns at the standard 1.18 multiplier per IS / RERA definitions) works out to about 1171 sqft. Total plot is 40 × 40 ft (1600 sqft).
What is the construction cost estimate?+
For Standard finish (branded cement, vitrified tiles, modular kitchen) the indicative band is around ₹46.2 L. For Premium finish (Italian marble, designer fittings, automation) the indicative band is around ₹83.1 L. These are concept-stage figures only and vary materially with city, labour rates, supplier choice, and finish specification. Excludes land, soil testing, approvals, and registration. A licensed quantity surveyor should confirm the final BOQ.
Can I download an AutoCAD DXF file from this plan?+
Yes. After generating your personalised layout you can export an AutoCAD-readable .dxf using AIA-standard layer naming (walls, doors, windows, dimensions, structural, electrical, plumbing). The export is on-demand from the layout page, not bundled with every generation.
Can I customise this 3 BHK layout?+
Yes. Use the "Generate My Plan" button above to enter your exact plot dimensions, facing bearing in degrees, BHK, jurisdiction pincode, and (optionally) owner birth details. The engine produces a fresh layout with Vastu scoring and a concept-stage cost band. MEP and structural-concept pages are part of the premium report tier.
Does this plan account for local building bylaws?+
The illustrative layout above uses conservative Delhi-style setbacks (front 5 ft, rear 3 ft, sides party-wall). When you generate your own plan, the engine attempts to resolve your six-digit pincode against the encoded bylaw set — currently covering 13+ Indian cities including Delhi, Gurugram, Lucknow, Mumbai (Island & Suburbs), and Bengaluru. Coverage is being extended; for cities outside the encoded set, defaults are applied with a clear caveat.
