Tata Realty and Infrastructure Limited (TRIL) is a wholly owned subsidiary of Tata Sons that functions as the Tata Group's real estate and infrastructure development arm. Tata Realty And Infrastructure Limited is a 100 per cent subsidiary of Tata Sons, and serves as a real estate and infrastructure development arm of the group. The company was set up with a commercial-real-estate mandate. When Tata Realty & Infrastructure Ltd was established in 2007, its primary focus was on commercial real estate. It has since grown into a diversified developer spanning offices, residences and infrastructure concessions, and in January 2024 it absorbed Tata Housing Development Company as a subsidiary, bringing the group's residential pipeline, including its Bengaluru hill address in Hosakerehalli, under one management structure. Tata Housing Development Company, which became TRIL's subsidiary in January 2024, recorded strong residential sales.
Tata Housing itself carries a longer institutional history in India. The company was established in 1984 by the late JRD Tata and was revived in 2006 under the leadership of Brotin Banerjee. Its Bengaluru credentials date back to that revival period: it pioneered the concept of sustainable green development with its first commercial project, Xylem in Bengaluru, the city's first sustainable IT park. That Bengaluru relationship continues today under Sanjay Dutt, Managing Director and CEO for Tata Realty and Infrastructure Ltd, with the combined group having delivered around 15 million sq ft across nine cities with a pipeline of 13 million sq ft at various stages of development. Elsewhere in Bengaluru, Tata Housing's Varnam project in the city's north corridor illustrates current buyer appetite for the brand: launched in August 2025, it achieved over ₹1,000 crore in sales within 60 days, selling 582 apartments and 48 townhouses.
In Hosakerehalli, on the Banashankari hills of South Bangalore, Tata Housing built The Promont, one of the few genuinely elevated residential sites in a city known for being flat. The Promont is the landmark hilltop residential apartment project launched in Hosakerehalli, Banashankari, Bangalore. The project was designed by an internationally recognised architect: Moshe Safdie, the architect behind Singapore's Marina Bay Sands, designed the project. Spread across a hilltop parcel, it comprises four towers named after their positions on the site. Four towers named Almora, Elana, Altezza, and Altura house 312 apartments. Tata Housing's own project description confirms the same scale: The Promont is one of Bengaluru's most coveted Hill Residences, comprising 312 uniquely crafted apartments and penthouses across 4 towers, amalgamating modern day luxuries and amenities amid 14 acres of lush natural landscapes.
The Promont is not a project on paper; it is a functioning community. Phase 1 houses 300+ families in an existing and thriving community with ready-to-use amenities. Occupancy certificates were granted in stages: Occupancy Certificates for Towers Elana and Almora were received on August 23, 2016, and for Towers Altura and Altezza on August 23, 2017. Units span the larger end of Bengaluru's luxury segment, with sizes ranging from 2,376 sq ft to 3,205 sq ft across 3 and 4 BHK configurations and penthouses. A notable design detail for the segment is space efficiency: carpet area efficiency runs above 71%, against roughly 65% for most luxury projects in the city. The in-house amenity list reflects the project's positioning within Tata Housing's luxury tier, including a golf course simulator, library, mini theatre, clubhouse, gym, swimming pool, and landscaped gardens. On resale platforms, this positioning is visible in pricing: The Promont's average asking price runs close to ₹14.3K per sq ft, against a broader Hosakerehalli average of about ₹12.7K per sq ft.
Tata Housing extended the address in 2024 with a second, more intimate phase on the same hill. Promont Phase II, developed by Promont Hilltop Private Limited, was officially launched on 1 August 2024 and is registered under RERA No. PRM/KA/RERA/1251/310/PR/300724/006953, with completion expected by 31 December 2028. Unlike the four-tower first phase, Phase II is deliberately low-rise: spanning the same 14.23-acre elevated terrain, it is planned across three specially curated blocks, each with four floors, offering new-age, low-rise living amid privacy and tranquillity. The scale is compact by design, with a total of 36 units distributed across the three towers. Configurations continue the Phase I format of 3 and 4 BHK residences, and entry pricing for the newer phase starts at a sale price for 3 BHK units from ₹2.97 crore onwards. The amenity set, in keeping with the Promont identity, spans a fully equipped clubhouse, landscaped gardens, gymnasium, swimming pool, recreation rooms, conference rooms, outdoor sports courts, children's play area, and party hall.
Hosakerehalli sits in South Bangalore, wedged between some of the city's most established residential markets. It lies near the Outer Ring Road and is regarded as a prominent locality in South Bangalore. Its immediate neighbours give the address weight for both end-users and long-term holders: the locality is surrounded by popular neighbourhoods like Banashankari, Jayanagar, and Kumaraswamy Layout, and is adjacent to the NICE Ring Road. For daily connectivity, residents draw on the Green Line's Banashankari Metro station, the nearest metro station to Promont Phase II being the Green Line Banashankari Metro Station, alongside the Mysore Road corridor and NICE Road. Infrastructure on the ground is also improving: a new flyover at the Hosakerehalli junction on the Outer Ring Road, easing traffic congestion at one of the city's most gridlocked junctions near PES College in Rajarajeshwari Nagar, is set to smoothen the Banashankari-to-Nayandahalli stretch that Promont residents use regularly.
Social infrastructure around the hill is dense rather than sparse. Educational institutions in the immediate catchment include PES University, Chaitanya School, Kumarans Schools, while healthcare access runs through DG Hospital and, further along Mysore Road and Kanakapura Road, larger multi-specialty facilities. This depth of schooling, healthcare and retail is consistent with the wider Banashankari micro-market, which scores high on social infrastructure, with several prominent schools, malls, and hospitals accessible to its residents. On pricing, the locality has shown durable appreciation rather than speculative spikes: property prices in Banashankari/Hosakerehalli increased by 40.39% over the period 2016 to 2025, a trajectory that aligns with The Promont's own asking-price premium over the broader locality average noted earlier. For a buyer evaluating a Tata Realty and Infrastructure Limited address, that combination, an institutionally backed developer, a hilltop site with a signature architect, an established resident community in Phase I, and a locality with steady, non-volatile appreciation, is the core of the pitch in Hosakerehalli.
