Note: Deputy CM D.K. Shivakumar stated at the Moneycontrol Future of Work summit that the second airport is likely to come up in south Bengaluru. The site has not been officially finalized, and the final decision rests with AAI and BIAL. This article explores what happens to property prices and where the real opportunities lie if the southern location gets confirmed.
For years, south Bengaluru has been the city’s quiet overachiever. It houses some of the most affluent neighbourhoods, sits at the doorstep of an increasingly important industrial belt, and has been quietly getting better road connectivity. What it has always lacked, and what north Bengaluru has loudly owned, is an airport. That might be changing.
At the Moneycontrol Future of Work summit, Deputy Chief Minister D.K. Shivakumar confirmed what many insiders had been speculating: the second international airport for Bengaluru is likely to come up in the south of the city. Two sites have been shortlisted there,The Karnataka government has identified 9,000 acres in South Bengaluru, particularly along Kanakapura Road (Choodahalli and Somanahalli), a third competing proposal exists on the Nelamangala-Kunigal Road in the north.
The final call belongs to the Airport Authority of India and BIAL, whose earlier exclusivity agreement is the real legal gatekeeper here, the broader political calculus, including the threat from Tamil Nadu’s proposed greenfield airport at Hosur, is nudging Karnataka toward the south.
This article is not about whether the airport will happen. It is about what happens to your property decisions if it does.
Why the South Makes Strategic Sense
Bengaluru’s existing airport at Devanahalli handled 40.73 million passengers in 2024, up from 37.2 million the year before. It is operating well beyond comfortable capacity and is projected to hit 55 million with Terminal 2 expansion. There is no question a second airport is needed.
The south has a compelling geographic argument. A large share of Bengaluru’s population, including residents of JP Nagar, Jayanagar, Banashankari, Kanakpura Road, Electronic City, and the entire Old Mysore belt, currently has to battle north Bengaluru traffic just to reach an airport. An official estimate suggests a south-side airport could be reached in about 30 minutes from Jayanagar.
More importantly, the south Bengaluru corridor connects to a significant chunk of Karnataka’s secondary cities. Mysuru, Mandya, Hassan, and Ramanagara would all find a southern Bengaluru airport far more accessible than driving to Devanahalli. This is the demand base that makes the case beyond just city residents.
The Tamil Nadu angle adds urgency. Hosur is barely 40 kilometres from south Bengaluru. A Hosur international airport, which Tamil Nadu has formally proposed, would siphon off considerable air traffic from south Bengaluru residents.
The Connectivity Stack Already Being Built
Here is what makes south Bengaluru different from most speculative corridors: there is meaningful infrastructure already in motion, and the airport story builds on top of it rather than requiring it from scratch.
Metro: The Namma Metro Green Line already runs to Silk Institute (Anjanapura) in the south, covering about 33 kilometres from Madavara in the northwest through Majestic and down Kanakapura Road. This is an operational metro line, not a future promise. Under Phase 4 proposals, BMRCL has specifically identified a 24-kilometre extension from the current southern terminus toward Harohalli, which is precisely where the airport sites are located. Metro to an airport southern terminal would be transformative in a way that rivals what the Purple Line did for Whitefield.
STRR (Satellite Town Ring Road): The 280-kilometre NHAI ring road connecting 12 towns around Bengaluru explicitly includes Kanakapura and Ramanagara in its alignment. Phase 2 of the STRR, which covers the southern arc through Magadi, Ramanagara, and Harohalli before looping back, is under construction. When complete, this ring road would allow freight and passengers to access a south airport without entering Bengaluru city at all. This is the kind of infrastructure that makes an airport viable, not just local. Phase 1 (the northern arc from Dobaspet to Hoskote) was inaugurated by the Prime Minister in March 2024.
NICE Road: The NICE Peripheral Ring Road already connects Tumkur Road in the north to Hosur Road in the south via Mysuru Road and Kanakapura Road. This is an existing access-controlled expressway that passes through the entire western flank of Bengaluru. The NICE Road cloverleaf junction near Kanakapura Road is already a strategic node and is one reason why Somanahalli, located between Kaggalipura on the east and Bidadi on the west, has come up in feasibility discussions.
NH 948 (Kanakapura Road): The six-lane upgrade of National Highway 209 (now NH 948) along Kanakapura Road is ongoing and will significantly reduce travel times from central Bengaluru southward.
Bengaluru-Mysuru Expressway: The already operational expressway cuts travel time to Mysuru to about 75 minutes and passes through Bidadi, which is another shortlisted area. Bidadi’s position sits at the intersection of the expressway and the NICE Road, giving it multi-directional connectivity that few emerging corridors can claim.
What Devanahalli Teaches Us
Before getting into specific opportunities, it is worth understanding what an airport does to property prices over time, because north Bengaluru gives us a fairly complete experiment.
Land in Devanahalli appreciated approximately 120 percent over the past decade, largely on the back of the Kempegowda International Airport and the industrial development that followed. Between 2022 and 2025 alone, prices in Devanahalli saw 35 to 40 percent appreciation driven by airport expansion, KIADB Aerospace Park activity, and STRR road development. IVC Road, the corridor closest to the airport, saw a roughly 49 percent price increase between 2019 and 2024 according to market data.
The pattern in Devanahalli followed a predictable arc. First, land prices moved on the airport announcement. Then, once commercial activity such as Boeing India, Hindustan Aeronautics, and logistics parks actually arrived, residential demand followed employment. The lag between announcement and full realisation was roughly eight to twelve years, but investors who entered within the first two years of serious announcement captured the bulk of the compounding.
South Bengaluru is at what you might call the early announcement stage. The difference from Devanahalli’s early days is that the industrial base already exists here. It was not waiting for the airport to justify it.
Harohalli: The Industrial Engine That Predates This Story
This is the part of the south Bengaluru story that most real estate coverage misses.
Harohalli Industrial Estate in Kanakapura Taluk, managed by KIADB, is already a functioning multi-phase industrial hub spread across more than 2,200 acres. It houses manufacturers in textiles, electronics, automotive components, and food processing. KIADB is in the process of developing a fifth phase at Harohalli, and a proposed fourth phase of 142 hectares (roughly 352 acres) at Cheeluru and Rampura villages has already gone through environmental clearance process.
This means the employment base that typically takes years to materialise around an airport already exists nearby. An airport at Harohalli would not be creating industrial activity from zero. It would be plugging into an industrial corridor that has been quietly growing for two decades. Cargo operations, logistics parks, and warehousing would find immediate demand rather than waiting for anchor tenants to set up.
Bidadi tells a similar story. The Bidadi industrial area hosts major manufacturers and sits at the junction of the Bengaluru-Mysuru Expressway and NICE Road. Toyota’s manufacturing operations in Bidadi have anchored steady industrial employment in the corridor for years. An airport in the vicinity would bring international logistics potential to a corridor that currently ships its goods by road.
Current Property Prices and What the Airport Premium Might Look Like
Kanakapura Road (operational corridor, 0 to 15 km from city edge): Apartments currently range from roughly Rs 7,000 to Rs 14,000 per sq ft in launch pricing, with government transaction data from Karnataka Revenue showing an average flat rate of approximately Rs 7,178 per sq ft. The corridor has already seen over 25 percent price appreciation in the past three years. Plotted developments range from Rs 3,000 to Rs 15,000 per sq ft depending on location and approvals.
Near Harohalli and proposed airport sites (25 to 45 km from city, precinct-level): Land here is in a far earlier stage. Plotted development by smaller builders and farm land conversions are still available at rates that are significantly below established corridors. This is speculative territory, similar to where Devanahalli was in 2012.
If the airport is confirmed and the Phase 4 metro extension to Harohalli gets sanctioned alongside it, analysts covering the Kanakapura Road corridor are estimating 30 to 40 percent property price appreciation over five years in the mid-corridor, with higher potential for land parcels closer to the actual airport site. These projections draw on the Devanahalli precedent and account for the existing connectivity base.
Where the Opportunities Actually Are Right Now
The market has not fully priced this in yet, which is the realistic window for investors. Here is how to think about different entry points.
The mid-corridor play on Kanakapura Road (Anjanapura to Kanakapura town): This is the sweet spot between already-expensive and still-speculative. Metro is here, the highway is being upgraded, and a second airport is being discussed. The 10 to 20 km stretch from the current Silk Institute terminus southward toward Kaggalipura and Thalaghattapura has legitimate demand drivers even without the airport, which makes it a lower-risk entry. If the airport confirms, this is where prices will move first and fastest because buyers will want the airport but without giving up city connectivity.
Major builders have already validated this belt. Puravankara acquired 3.63 acres in Vajrahalli with a GDV of Rs 700 crore. Prestige Falcon City is established here. Assetz Meru and Meadow, Sattva Misty Charm, and Vanshikas Natures Harmony have active launches. When Prestige, Puravankara, and Assetz are all placing bets on the same corridor simultaneously, the signal is worth noting.
Plotted developments near Harohalli (the long-shot, high-upside play): This requires higher tolerance for uncertainty and a longer holding period. If the airport site is confirmed at either of the Harohalli locations, land prices in the surrounding 5 to 10 km radius could appreciate dramatically and quickly. The catch is that land acquisition timelines, farmer protests (which have already begun in the area over airport land concerns), and the AAI feasibility process make the timeline genuinely uncertain.
For this kind of investment, legal due diligence on title and conversion status is non-negotiable. Revenue site land that has not gone through DC conversion is not bankable and is not easily resaleable to end users.
Bidadi on the Mysuru Expressway corridor: Bidadi is the quieter but arguably better-connected option. The Mysuru Expressway already runs through it, NICE Road intersects it, and KIADB has industrial presence here too. If the final airport site shifts closer to Bidadi rather than Harohalli, this corridor gets a direct lift. Even as a residential destination independent of the airport thesis, Bidadi’s connectivity is improving structurally. Plots in the Rs 40 to 80 lakh range are available from credible developers here.
Warehouse and logistics land along the STRR southern arc: This is the commercial and institutional investor angle. When STRR Phase 2 connects Ramanagara and Harohalli into the ring road network, freight and logistics operators will want staging points at or near the junctions. Land near STRR intersections along the Kanakapura-Ramanagara belt is still available at a significant discount to comparable land near the northern STRR stretches around Devanahalli and Hoskote.
What to Watch as a Signal That This Is Real
There are a few concrete events that will confirm or deny the south airport thesis over the next 12 to 18 months.
The AAI feasibility report is the most important. AAI has been doing site inspections at the shortlisted locations, and their report will carry actual technical conclusions on whether the Harohalli sites are viable. Watch for any government announcement citing AAI’s recommendation.
Land acquisition notification under RFCTLARR would be another strong signal. The moment Karnataka issues a Section 11 or Section 19 notification for land around any of the shortlisted southern sites, the surrounding property market will move fast.
Metro Phase 4 DPR progress is a correlated signal. BMRCL has been finalising a 197-kilometre feasibility study covering eight corridors. If the Harohalli extension appears in the submitted DPR with government approval, it independently validates the south corridor even before the airport is confirmed.
The Realistic Risk Assessment
Not every infrastructure story plays out as expected. The PRR (Peripheral Ring Road, also called Bengaluru Business Corridor) has seen two cancelled tender processes and remains stuck in land acquisition despite being planned for years. Large-scale road and infrastructure projects in Bengaluru routinely face delays.
Farmer protests over land acquisition have already started in the area. Land assembly for any airport requires significant displacement, and the compensation and legal processes tend to run long.
None of this makes south Bengaluru a bad bet. It makes it a patient bet. The infrastructure stack in the south, from the Green Line metro to the STRR to the Mysuru Expressway, is real and functional. The industrial base at Harohalli and Bidadi is genuine. AI city Push for Bidadi is also strong. The demographic logic of a second airport serving south Bengaluru and southern Karnataka is sound. The airport would accelerate timelines that are already underway.
The Bottom Line
South Bengaluru was always going to grow. The airport story makes it grow faster and farther. But in real estate, the best time to pay attention to a signal is before the market has already reacted to it.
The mid-corridor on Kanakapura Road between the Anjanapura metro and the Harohalli industrial zone is the area worth watching closely right now. It sits at the intersection of verified demand, improving connectivity, and speculative upside. Devanahalli took about a decade to fully realise its airport premium. South Bengaluru already has a head start in most of the supporting infrastructure. If the airport confirmation comes through, the realisation here might be faster.
