30×40 plot house construction cost in Bangalore

A 30×40 site in Bangalore (1,200 sqft of land) is the benchmark residential plot across the city, from BDA layouts in south Bangalore to the new peripheral areas around Sarjapur Road, Electronic City, and Devanahalli. At a G+1 configuration, BBMP mandates setbacks that vary by road width but typically reduce the usable footprint to 600 to 720 sqft per floor. The resulting built-up area of 1,200 to 1,440 sqft accommodates a 3 BHK on the ground floor and a 2 or 3 BHK on the first floor. This site is also the standard for Bangalore duplexes. A 30×40 duplex with separate entrances is one of the most common construction briefs in the city.

On cost, a 30×40 G+1 in Bangalore sits in the mid-market zone where construction quality matters most. At standard quality (₹2,000–₹2,800 per sqft), your civil cost runs ₹28.8 to ₹40.3 lakh. The spread within that range depends on two things: location and soil. North Bangalore plots on hard laterite (Yelahanka, Hebbal, Devanahalli) hit the lower end of the range because foundations are shallow and labour is less congested. East Bangalore plots near the IT corridor (Whitefield, Sarjapur, Marathahalli) trend higher due to labour demand and softer soil in lake-adjacent areas. Central Bangalore plots (Indiranagar, Koramangala) always hit the top of the range, because logistics cost more when ready-mix trucks can't get close.

The full move-in cost on a 30×40 G+1 in Bangalore, adding BBMP approval, BESCOM connection, borewell, compound wall, and basic interiors, typically runs ₹38 to ₹58 lakh at standard quality. The approval route matters: a BDA-approved plot in a formed layout moves faster than a converted agricultural land parcel, where the khata transfer and BDA conversion add time and cost. If you are comparing quotes from Bangalore builders, make sure the BOQ specifies whether the per-sqft rate includes UPVC windows, teak main door, and Jaquar-equivalent fittings. These are standard in mid-range Bangalore quotes but are sometimes excluded to lower the headline number.
