30×40 house construction cost in Bangalore (2026)
Realistic 2026 cost ranges for building on a 30×40 site in Bangalore, what drives the number, and what is not included. All figures are ranges for planning, not quotes.
If you own or are buying a 30×40 site in Bangalore, the first question is usually what it will cost to build. This guide gives grounded 2026 ranges, explains what moves the number, and lists what the per-square-foot rate does not cover.
Quick answer: A 30×40 G+1 home (about 2,400 sq ft built-up) costs roughly ₹50 to 65 lakh at standard quality in Bangalore as of July 2026. That is construction only, and excludes land, interiors and government approvals.
What is a 30×40 site?
A 30×40 site is 1,200 sq ft (30 feet by 40 feet), one of the most common residential plot sizes in Bangalore. After the setbacks that apply in the Greater Bengaluru Area on the front, rear and sides, the ground-floor footprint is smaller than 1,200 sq ft, so you gain living area by adding floors. Use our land unit converter if you need to convert between sq ft, cents and other units.
Cost by number of floors
Built-up area is roughly the plot area multiplied by the number of floors. At standard quality (₹2,100 to 2,700 per sq ft), the ranges work out as follows.
| Configuration | Approx built-up | Standard cost range |
|---|---|---|
| Ground floor only (G) | ~1,200 sq ft | ₹25 to 32 L |
| G+1 | ~2,400 sq ft | ₹50 to 65 L |
| G+2 | ~3,600 sq ft | ₹76 to 97 L |
| G+3 | ~4,800 sq ft | ₹1.0 to 1.3 Cr |
Built-up area is approximate and depends on your setbacks and design. For your own numbers, try the construction cost calculator.
Cost by construction quality
The quality tier decides your finishes, fittings and materials. Here is the range for a typical G+1 (about 2,400 sq ft built-up).

|---|---|---|
| Basic (economy) | ₹1,750 to 2,200 | ₹42 to 53 L |
| Standard (mid-range) | ₹2,100 to 2,700 | ₹50 to 65 L |

How to keep your 30×40 build on budget
- Freeze the plan and specification before work starts; changes mid-build are the biggest cost creep
- Choose finishes early so quotes are comparable
- Ask for an itemised quote, not just a per-sq-ft number
- Keep a contingency aside
- Compare two or three verified builders on scope, inclusions and warranty, not price alone
Where the plot sits matters as much as how big it is. The same 30×40 build meets different ground and a different approving authority in Whitefield, on Sarjapur Road and around Electronic City. Our area by area pages set out what changes.
