Birla Trimaya Phase 4 'The Bay' Launched in Devanahalli, Clocks ~₹649 Crore in Bookings in FY26

Birla Trimaya Phase 4 Receives RERA Approval and Opens to Bookings

On January 17, 2026, Birla Trimaya Phase 4 received RERA approval under registration number PRM/KA/RERA/1250/303/PR/290126/008436. The phase, marketed as 'The Bay', opened to bookings shortly thereafter and swiftly accumulated approximately ₹649 crore in pre-launch sales, marking another validation of investor confidence in the ongoing Birla Trimaya township development.

Phase 4 in the Broader Township Context

Birla Trimaya spans 52 acres with 2,600 homes planned across 28 residential towers in multiple phases. The township now comprises four phases—Phase 1 (The Hill), Phase 2 (The Park), and Phases 3 and 4 (The Bay)—launched between 2023 and early 2026. Phase 1 sold out after launch in September 2023, with possession expected between 2027 and 2028. Phase 2 also sold out and is expected to complete by 2029.

Unit Mix and Configuration

The township offers a mix of 1, 2, 3, and 4 BHK apartments, duplex homes, villaments, and around 40 row houses. Home sizes range from 489 sq. ft. to 3,050 sq. ft., providing spacious and comfortable living areas. Phase 4 specifically focuses on larger configurations; it includes 2 BHK (798–813 sq. ft.), 3 BHK (1,084–1,413 sq. ft.), and 4 BHK duplex homes (2,077–3,023 sq. ft.).

Location and Connectivity

Birla Trimaya is strategically located at Shettigere, Devanahalli, just 2–3 minutes from NH-44 and around 7 km from Kempegowda International Airport. The township is 2 kilometres before Kempegowda International Airport on Shettigere Road. The upcoming Namma Metro Blue Line (Airport) station is just 2.5 km away from the project. The KIADB Aerospace Park's employment density has grown with operational headcount at Boeing India, Airbus Technology Centre, Shell R&D Campus and multiple Tier 1 aerospace suppliers. The NH-44 corridor has improved travel times to Manyata Tech Park and Hebbal to approximately 25–35 minutes. The Blue Line Metro Phase 2B (Doddajala station, 2.5 km from Birla Trimaya) is under active construction and expected operational by 2027–2028.

Township Amenities and Design

The township features three grand clubhouses totaling about 75,000 sq. ft., making it one of the largest planned residential communities in the North Bengaluru airport corridor. The township is built around a 2.5-acre man-made lake and has nearly 35 acres of green open space, with more than 80% open area maintained. The towers range from 2B+G+12 floors up to G+14 and G+16 structures depending on the phase.

Devanahalli's Market Momentum

Phase 1 (550 apartments) sold out within three days of launch in September 2023, which is one of the strongest demand validation signals any Bangalore new launch has produced in recent memory. Birla Estates—fresh from its successful launches in Birla Alokya (Whitefield)—brought a 52-acre township to a corridor where no branded developer had attempted that scale before. The combination of Birla brand, airport proximity, metro alignment and competitive pricing produced the three-day sellout.

New projects in Devanahalli are emerging as one of the strongest real estate growth corridors in North Bengaluru, driven by the Kempegowda International Airport and large-scale infrastructure developments like the Satellite Town Ring Road (STRR) and upcoming Blue Line metro extension connectivity. The area is a key growth hub driven by major developments like the KIADB Aerospace Park, Devanahalli Business Park, and upcoming STRR and metro connectivity plans. The region's real estate market recorded transactions worth ₹4,200 crores in 2024, with residential properties accounting for 68% of total investments.
