Devanahalli and the airport belt
House construction cost in Devanahalli, Bangalore (2026)
The belt where a different authority approves your plan and the airport can cap your height. What building near Kempegowda costs, and what to verify first.
The airport belt is the fastest-appreciating stretch around Bangalore and the one where the most money is lost on paperwork. Two things make it different from anywhere else covered on this site: your plan is approved by a dedicated airport-area planning authority rather than a city corporation, and the airport itself can limit how tall you build no matter what the city rules allow. Neither shows up in a per-square-foot rate.
Quick answer: A 30×40 G+1 in the Devanahalli belt, about 2,400 sq ft built-up, costs roughly ₹50 to 65 lakh at standard quality as of July 2026. Add ₹2 to 5 lakh for a borewell and storage, since piped supply does not reach most of this belt. Construction only: land, interiors and approvals are separate.
Who sanctions your plan here
Development around Kempegowda International Airport is regulated by BIAAPA, the Bengaluru International Airport Area Planning Authority. It covers a large planning area of roughly 1,800 sq km taking in Devanahalli, Chikkajala, Bagalur, the Doddaballapur Road stretch and parts of the Nandi Hills side, and its approval process is more detailed than an ordinary municipal permit. A city corporation is not your authority out here.
| Where your site is | Who approves the building plan | What to check |
|---|---|---|
| Within the BIAAPA planning area | BIAAPA | That your layout appears on BIAAPA’s own list of approved layouts, which the authority publishes |
| Inside Devanahalli town limits | The town municipal body, within the BIAAPA planning framework | Which body issues your khata, and whether it is A-khata |
| Anywhere on the flight path side | BIAAPA, plus a height clearance from the airport authority | The permitted height for your exact location, before you design floors |
The height trap
Building near an airport requires a no-objection certificate from the airport authority to protect air safety, and that clearance governs your maximum height irrespective of what the city bye-laws permit. This matters more in 2026 than it used to: the Greater Bengaluru amendment raised residential height to 15 m elsewhere in the city, but an airport height restriction can still hold you below that. Establish your permitted height in writing before you pay for a design with three floors in it.
Note also that the 2026 relaxations were made under the Greater Bengaluru regulations. BIAAPA operates its own planning framework, so do not assume the reduced setbacks and higher unit counts automatically apply to your plot. Ask specifically.
Unapproved layouts are the local hazard
The airport corridor has attracted a long run of layouts promoted without proper sanction, and the pattern is well documented. A plot in an unapproved layout cannot get a building plan sanctioned, which also means no clean construction loan and a painful resale. Because the approved-layout list is published by the authority, this is one of the few property risks in Bangalore you can check yourself in an afternoon. Do it before you pay a token advance, not after.
Typical sites and what you can build
| Site type | Common dimensions | What people usually build |
|---|---|---|
| Plot in a sanctioned plotted development | 30×40 (1,200 sq ft), 30×50 (1,500 sq ft) | G+1 home, often built later than the land purchase |
| Villa plot | 40×60 (2,400 sq ft), 50×80 (4,000 sq ft) | Villa or duplex, subject to the height clearance |
| Larger holding further out | Varies, often sold in guntas or acres | Check conversion and planning sanction before assuming a house is possible |
What moves your cost here
Water is entirely your own infrastructure
Piped Cauvery supply does not reach this belt. A new house means a borewell, a properly sized sump and tanker water through construction, for curing as much as for the workers. The wider constraint applies here too: BWSSB has stopped accepting new borewell applications because of over-extraction, so an existing legal borewell on a plot is a material asset rather than a detail. Confirm its yield, not just its existence.
Good roads, thin local supply chain
Arterial access along the airport road and NH-44 is genuinely good, so material delivery is easier than on the eastern corridors. What is thinner is everything local: fewer established contractors working nearby, longer hauls from ready-mix plants, and labour that may travel in. On a single house that shows up as slower progress rather than a higher rate, but a builder who has actually completed projects in this belt is worth more here than in a mature area.
Building later than you bought
Many plots in this belt are bought as an investment and built on years later. Two costs follow. Boundary walls and basic security become necessary early to protect an idle plot, and the specification you assumed at purchase will be out of date by the time you build, because package rates move. Budget from current rates when you actually start, not from the figure you were quoted when you bought the land.
Cost ranges for common builds
Package rates are city-wide, set by specification and market rather than by locality. Standard quality is ₹2,100 to 2,700 per sq ft as of July 2026.
| Site and configuration | Approx built-up | Standard-quality range |
|---|---|---|
| 30×40, G+1 | ~2,400 sq ft | ₹50 to 65 L |
| 30×50, G+1 | ~3,000 sq ft | ₹63 to 81 L |
| 40×60, G+1 villa | ~4,800 sq ft | ₹1.0 to 1.3 Cr |
| 50×80, G+1 villa | ~8,000 sq ft | ₹1.7 to 2.2 Cr |
Add, for this belt: borewell and storage, boundary wall and security if the plot sat idle, and a contingency for the thinner local supply chain. Run your own numbers in the construction cost calculator.
Before you buy or build in the airport belt
- Check the layout against BIAAPA’s published list of approved layouts, yourself, before paying anything
- Get your permitted height in writing, including the airport authority clearance position, before designing floors
- Ask whether the 2026 Greater Bengaluru relaxations apply to your plot at all, since BIAAPA has its own framework
- Confirm which body issues your khata and whether it is A-khata
- Confirm borewell yield, not just that a borewell exists
- Choose a builder who has actually completed work in this belt
Frequently asked questions
What does BIAAPA approved actually mean?
It means the layout your plot sits in was sanctioned by the Bengaluru International Airport Area Planning Authority, which regulates development around the airport. It is the approval that lets a building plan be sanctioned. Treat the phrase in an advertisement as a claim to verify against the authority’s own published list, not as proof.
Can I build three floors near the airport?
Possibly, but height near an airport is governed by an airport authority clearance for air safety, and that can hold you below the city height limit. The 2026 increase to 15 m elsewhere in Bengaluru does not override it. Get your specific permitted height confirmed before you commission a design.
Is Cauvery water available in Devanahalli?
No, this belt is outside piped supply, so plan for a borewell and storage. Check the yield of any existing borewell during due diligence, and remember that new borewell applications are no longer being accepted, which makes a working one on the plot valuable.
Is it cheaper to build here than in the city?
The package rate is the same. Land is cheaper, which is the real reason people build here, but you spend more on water infrastructure and you carry the cost of a thinner local supply chain. The construction budget is not materially lower.
