Birla Trimaya Phase 1
Birla Trimaya Phase 1 is a building-stage apartment project by Birla Estates in North Bangalore's Devanahalli. It was the first registered part of Birla Trimaya, a township of about 52 acres off Shettigere Main Road, and it covers roughly 5.77 acres of that land. Its 556 homes are due by 31 October 2028.
Flats with one, two or three bedrooms fill seven mid-rise towers, and an eighth, Tower 31A, holds a dozen duplexes with private lawns. Birla Arnaa LLP, the promoter, joins Birla Estates with MSR Realty, which owns the land. Since a single home remained free in the July 2026 filing, most new buyers look at the township's Phase 4 launch instead.
The phase in brief:
- Developer: Birla Estates
- Locality: Devanahalli, near the airport
- Homes: 556, including 12 duplexes
- Status: 63% built, nearly all booked

Birla Trimaya Phase 1 Price Details
Birla Trimaya Phase 1 counts as sold out for practical purposes, so the unit table carries no live prices. Every home type is marked sold, as just one of the 556 remained open in mid-2026.
Entry now comes through a resale or transfer of an allotted flat, subject to the developer's consent before handover. What a seller asks will depend on tower, storey, outlook and the instalments already paid. Stamp duty and registration charges come on top.
