RUSTOMJEE ANDHERI EAST

Founded in 1995 by Boman Rustom Irani, Keystone Realtors Limited operates under the Rustomjee brand and has spent three decades reshaping the Mumbai Metropolitan Region's residential and mixed-use landscape. What began with a single project — Rustomjee Residency — grew into one of MMR's most recognised development groups, listed on Indian stock exchanges in November 2022. The company is headquartered at Andheri East, Mumbai, and has attracted institutional partners including HDFC Capital Affordable Real Estate Fund-3, IIFL Special Opportunities Funds, and Singapore-based Keppel Land Limited as a strategic partner in Kapstone Constructions.

Rustomjee's approach treats the home as a context for community rather than a unit of area — a philosophy crystallised in the brand line "Life Shouldn't Be Lived in Square Feet." To substantiate that belief, the company partnered with Dr. Robert Waldinger, director of Harvard University's longitudinal happiness study, to inform how its developments are planned and programmed. Tree-lined walkways, gated open spaces, and integrated social infrastructure are not add-ons; they are designed into the brief from day one, whether the project is an affordable apartment block in Dahisar or an ultra-premium tower at Prabhadevi.

The portfolio spans every price tier the MMR market carries. Rustomjee has delivered 34 completed projects and maintains 13 ongoing projects and 28 forthcoming projects across the region, having developed over 20 million square feet of residential buildings, integrated townships, gated estates, corporate parks, retail spaces, schools, and iconic landmarks. Named projects range from the Urbania integrated township in Thane and Global City in Virar to Rustomjee Crown on Prabhadevi's skyline, Rustomjee Paramount in Khar, and Rustomjee Seasons in Bandra Annexe. In 2024 the group entered plotted development with Belle Vie at Kasara, and in 2025 launched a slate of landmark projects including Balmoral Golf Links, Chembur Crescent, and Pali Hill Cliff Tower.

Rustomjee's ownership philosophy holds that buying a home is the realisation of a significant life ambition, not a transaction. The company's internal design standard — "Better, not cheaper" — applies from structural specification through to landscape and amenity detailing. The group has delivered over 230 buildings that house more than 17,000 families across Mumbai, and its CSR programmes have touched over 100,000 lives through vocational training, community health initiatives, and environmental projects including a commitment to plant 50,000 trees under the Go Green Kasara initiative. That civic accountability sits alongside a public-company governance structure and a track record of project completions that reinforces confidence for buyers planning long-term ownership.
