Construction cost estimator — Bengaluru

Plot area is the land you own — length × width at ground level. Built-up area is the total covered floor space across all floors, including walls. This estimator starts from your plot and derives built-up area using the service's coverage factors; the result always shows both figures so you can see the conversion.

It is a planning range, roughly ±8% around a base figure, meant for early budgeting. Soil, design choices, and market movement shift real costs. A binding figure exists only in the signed, itemised agreement after site study and design freeze — any page that promises more from three inputs is guessing.

Each added floor contributes its own covered area at the tier rate, shown separately in the floor-wise table. Upper floors are usually slightly smaller than the ground floor because of staircases, cut-outs and setbacks — the service's factors handle that, and the per-floor areas are visible in your result.

They are counted as additions outside the main floor plates, each with a stated square-foot allowance priced at your selected tier rate. Your result lists the count, the allowance, and the cost line for each, so nothing hides inside a lump sum.

Land cost, statutory approval fees and deposits, loose furniture and appliances, landscaping and interiors beyond the spec sheet, and any specialised foundations that only a soil test can reveal. Exclusions travel with every estimate and are listed in full beside it.

Yes. Normal soil is assumed, with a two-point soil test included in the design stage. Black cotton soil, filled-up plots, high water tables or nearby basements can demand deeper or specialised foundations, which are priced separately after the test — never averaged into the planning rate.

Sanctions are issued by the authority, not by us. Our approvals liaison coordinates drawings, files and follow-ups, but no one can promise sanction timelines on the authority's behalf. Approval fees and deposits sit outside the construction range.

Essential covers a sound structure with standard finishes for practical homes. Classic steps up finishes and fittings and suits most family homes. Elite is for premium finishes throughout. The spec-comparison table below the estimator shows the differences category by category; you can tap between tiers on any result to compare instantly.
