The real cost of building a home in Bengaluru in 2026
A line-by-line look at what a G+1 house actually costs on a 30×40 plot — from cement to key handover.
If you're planning to build in Bengaluru right now, the honest answer to "what will it cost" is: it depends on what's on your specification sheet. Two contractors can both quote ₹1,800 per sq ft and deliver houses that feel worlds apart, because the material grade and brand hiding inside that per-sq-ft rate does most of the work.
The 30 × 40 baseline
A standard G+1 on a 30 × 40 plot in Bengaluru works out to roughly 1,800–2,000 sq ft of built-up area, depending on setbacks and staircase design. At our Standard package (₹1,679/sq ft), that's a total build cost in the ₹30–33 lakh range — turnkey, materials included, no design or approval fees added later.
At Luxury (₹1,949) the same house runs closer to ₹35–39 lakh. The difference isn't just paint and tiles — it's the block wall thickness, the TMT brand, the switchgear, and whether your waterproofing is a coating or a proper Fosroc treatment.
What isn't in the per-sq-ft number
Three costs sit outside the construction rate for almost every builder in the city: BBMP plan-sanction fees, the compound wall, and any interior work beyond the base fit-out (modular kitchen, wardrobes, false ceiling). If a quote looks unusually low, check whether these have quietly been excluded.
The 2026 material squeeze
Steel prices have moved sideways this year, but sand availability in the South Bengaluru corridor has been tighter than usual since late 2025. Expect a small rate revision on manufactured sand if your project starts after the monsoon.
