Birla Trimaya Phase 4, also positioned by Birla Estates as The Bay, is the newest residential phase within the larger Birla Trimaya township in Devanahalli, North Bangalore. The project combines premium apartment living, a water-centric landscape concept, large green areas and proximity to Kempegowda International Airport, making it one of the more notable new launches in the North Bangalore airport corridor in 2026.
Official Birla Estates information confirms that the larger Birla Trimaya township spans approximately 52 acres at Shettigere Main Road, Devanahalli. Phase 4 introduces 548 LifeDesigned® residences with 1, 2, 3 and 4 BHK options, while current RERA-linked property listings also show selected 3.5 BHK and duplex formats. The development is registered under Karnataka RERA number PRM/KA/RERA/1250/303/PR/290126/008436.
Buyers researching Birla Trimaya phase 4 are effectively buying into a much larger township ecosystem rather than a standalone apartment complex. This distinction matters because common amenities, green spaces and larger infrastructure are being developed across different phases.

Why Can Prices Change?
Two apartments with similar square footage can still have different final prices because of:
- Tower
- Floor
- Bay-facing position
- Central landscape views
- Apartment orientation
- Corner unit
- Floor-rise charges
- Current launch inventory
- Parking allocation
- Preferred-location charges
- Clubhouse charges
- Taxes and registration
A water-facing or highly open unit can command a premium over a comparable inward-facing residence.
Headline Price vs All-In Cost
Buyers should calculate the complete acquisition cost.
Request a written cost sheet covering:
- Basic apartment value
- Floor-rise charges
- Preferred-location charges
- Car parking
- Clubhouse charges
- Maintenance deposit
- Corpus fund
- GST, where applicable
- Stamp duty
- Registration charges
- Documentation fees
- Any other mandatory charges
The current Housing.com pricing specifically excludes items such as maintenance, floor-rise cost, stamp duty, registration and GST, reinforcing the need to calculate the total purchase budget.
Is Birla Trimaya Phase 4 Expensive?
The price should be evaluated against its positioning.
Buyers are paying for access to:
- Birla Estates branding
- 52-acre township ecosystem
- Airport-corridor location
- Water-centric Phase 4 design
- 73% green/open-space positioning
- Large community amenities
- Multiple apartment formats
- RERA-registered development
It should therefore be compared with other large North Bangalore townships rather than isolated apartment projects.
Which Configuration May Offer Better Value?
1 BHK
Can suit:
- Single professionals
- Couples
- Lower-ticket investors
- Buyers wanting airport proximity
2 BHK
May provide a stronger balance between:
- Price
- Family usability
- Rental demand
- Resale liquidity
3 BHK
Can suit:
- Growing families
- Long-term end-users
- Buyers wanting additional storage and privacy
3.5/4 BHK or Duplex
Targets:
- Luxury buyers
- Larger families
- Buyers prioritizing space
- Premium long-term end-users
The best configuration is the one that matches the household’s actual usable-space needs, not simply the largest available option.

Birla Trimaya Phase 4 Master Plan
The Birla Trimaya phase 4 Master Plan forms part of the larger 52-acre Birla Trimaya development.
The defining feature of Phase 4 is The Bay, a man-made water body that acts as a central geographic and lifestyle anchor. Birla Estates describes the water feature as influencing sightlines, microclimate and the overall experience of the community.
Township Planning Highlights
Current project information includes:
- Approx. 73% open green areas
- Central lake/bay
- 21,000+ sq ft clubhouse
- Landscaped promenades
- Pavilions
- Cricket ground
- Swimming facilities
- Sports infrastructure
- Children’s recreation
- Walking and jogging zones
Why the Water Feature Matters
A large central water body can potentially provide:
- Better views
- Greater landscape openness
- Distinct project identity
- Premium-facing apartments
- Relaxation spaces
- Better visual separation between built zones
However, buyers should verify which tower and unit actually receives a permanent water-facing view.
Phase-Wise Development
Birla Estates explicitly states that Phase 4 forms part of a larger layout and that common areas and amenities are being developed in phases.
This means buyers should ask:
- Which amenities are phase-specific?
- Which are shared?
- When will shared amenities be delivered?
- Can Phase 4 residents use facilities in other phases?
- What are the maintenance implications?
These questions are particularly important in integrated townships.
Birla Trimaya Phase 4 Location: Devanahalli, Shettigere & Airport Connectivity
The Birla Trimaya Phase 4 Location is on Shettigere Main Road in Devanahalli, North Bangalore, before Kempegowda International Airport.
Birla Estates lists the address as:
Property No. 103, Shettigere Main Road, Devanahalli, Bengaluru.
Buyers can study the detailed Birla Trimaya phase 4 Location before planning their site visit.
Key Connectivity Drivers
The location provides access toward:
- Kempegowda International Airport
- Airport Road
- NH 44
- Devanahalli
- Shettigere
- Doddajala
- Yelahanka

Airport proximity can be particularly useful for:
- Frequent travelers

Why Devanahalli Is Important
Devanahalli is no longer evaluated only as an airport location.
The wider corridor is influenced by:

- Warehousing
- Industrial growth

These economic drivers can gradually create a stronger residential base.
Upcoming Metro Connectivity
Current project material emphasizes upcoming Metro connectivity as part of the long-term infrastructure story.
Metro infrastructure can potentially improve:
- Airport access
- Employment connectivity
- Public transport
- Rental demand
- Long-term residential appeal
Buyers should nevertheless separate operating infrastructure from future infrastructure when making an investment decision.
Yelahanka and Hebbal
Yelahanka and Hebbal provide access to more mature urban infrastructure including:
- Hospitals
- Schools
- Retail
- Offices
- Established residential neighborhoods
For Devanahalli residents, these locations may continue to function as important urban support zones until local social infrastructure becomes even more mature.
Nearby Social Infrastructure
Current project-market information identifies:
- Akash International School
- Akash Hospital
- Devanahalli Old Bus Stand
- restaurants and local retail
Housing.com places Akash International School at approximately 4.7 km and Devanahalli Old Bus Stand at roughly 3.3 km from Phase 4.
Who Is the Location Best Suited For?
| Buyer Profile | Suitability |
|---|---|
| Airport professional | Very High |
| Frequent traveler | Very High |
| North Bangalore employee | High |
| Long-term investor | Potentially High |
| Central Bengaluru commuter | Commute-dependent |
| Electronic City professional | Relatively low |
The project should be evaluated based on actual household travel patterns rather than airport proximity alone.

Birla Trimaya Phase 4 RERA, Birla Estates Profile & Investment Potential
The Birla Trimaya Phase 4 Rera Number is:
PRM/KA/RERA/1250/303/PR/290126/008436
The project was registered on 29 January 2026, and Birla Estates itself publishes this registration on its official project website.
Buyers can review the dedicated Birla Trimaya phase 4 Rera Number page before independently checking Karnataka RERA.

- Payment schedule
- Possession commitment
all correspond specifically with PRM/KA/RERA/1250/303/PR/290126/008436.

Buyers should use the possession schedule in their final Agreement for Sale as the contractual reference.

Birla Estates is the real estate development arm associated with the Aditya Birla Group and operates across premium residential and commercial development.

Why Developer Reputation Matters
A 52-acre phased township requires long-term execution across:
- Residential towers
- Roads
- Utilities
- Landscapes
- Water features

- Safety infrastructure
- Facility management
Buyers are therefore assessing not just one building but the developer’s ability to execute a larger ecosystem.
