30x40 House Construction Cost in Bangalore 2026: Real Numbers

Bangalore is the most competitive construction market in Karnataka, and also the one where quoted numbers vary most wildly. Here is what a 30×40 actually costs on our 2026 Bangalore rate card.

How Much You Can Build

A 30×40 site is 1,200 sqft. What you can build on it is governed by FAR (Floor Area Ratio), which in BBMP areas ranges from 1.75 to 3.25 depending on plot size, zone and the width of the road you front.

For a typical 30×40 residential plot at FAR 1.75, you get about 2,100 sqft of built-up area across floors.

G+2 on a 30×40 usually requires a wider road frontage to qualify for the higher FAR. Confirm your specific FAR before designing — it is the number that decides everything else.

Turnkey Cost by Package — 30×40 in Bangalore

G+1 (~2,100 sqft) — the most common configuration

G+0 (~1,100 sqft)

G+2 (~3,100 sqft)

Bare shell (structure only, G+1 ~2,100 sqft)

Bare shell makes more sense in Bangalore than elsewhere, because many owners want to phase the interior spend or use their own designer. You get the structure, masonry and MEP rough-in; finishes are yours to arrange.

What Changes Between Packages

Moving from Essence to Select on a 30×40 buys:

• Floor height 10'0" → 10'6"
• 2×2 vitrified → 2×4 vitrified flooring
• Aluminium 3-track → UPVC 3-track windows
• Teak main door ₹22,000 → ₹30,000
• Granite staircase, included
• Terrace waterproofing, included
• Parking floor tiling, included

Imperial moves you to granite flooring throughout, Indus/Jindal Panther/Vizag steel, 11'0" floor height, Tractor Shyne interior with Apex exterior paint, and an 8,000L sump.

For a rental-income build, Essence is usually the right call — tenants do not pay a premium for 2×4 tiles. For a home you intend to live in for twenty years, the Select upgrades are the ones that show.

Bangalore vs the Tier-2 Cities

Worth understanding if you are comparing across our markets:

Bangalore's per-sqft rate is marginally lower, but BBMP approval costs roughly double to triple the tier-2 equivalent. The higher FAR usually offsets it — you can simply build more on the same plot.

Costs Outside the Per-Sqft Rate

Budget an extra ₹5–8 lakhs over the construction figure for a 30×40 G+1 once approvals, compound wall, borewell and utility connections are in. Bangalore's borewell depths and BWSSB charges are the main reason this is higher than in Shivamogga or Davanagere.

Build Time

12–15 months for a G+1 from foundation to handover; 6–9 months for a single floor.

BBMP sanction itself takes 45–75 days and should run in parallel with your design finalisation, not after it. That sequencing alone saves most Bangalore owners a month.
