Keystone Realtors Limited — the BSE- and NSE-listed entity behind the Rustomjee brand — has been building across Mumbai since 1995. Founded in 1995 and operating exclusively within the Mumbai Metropolitan Region, the company has delivered projects under affordable, mid and mass, aspirational, premium, and super premium categories, all under the Rustomjee name. Its portfolio spans 14.32 million square feet of completed projects, 12 million square feet of ongoing development, and a further 28 million square feet of planned development in the pipeline across the MMR. Borivali is not a peripheral experiment for the developer — Rustomjee's active portfolio includes residential spaces, office complexes, retail developments, and educational institutions spread across Borivali, among other established Mumbai micro-markets.
Rustomjee Summit is located on Dattapada Road, near the Borivali Flyover, in Rajendra Nagar, Borivali East. It is a 37-storey tower with 2 and 3 bedroom homes. The project has 240 total units registered under MahaRERA, with apartments from 65.58 sq m onwards. The MahaRERA registration number is P51800003590, verifiable on the MahaRERA website.
Apartment sizes in the project range from 720 sq ft to 1,220 sq ft. Bank loans for Rustomjee Summit have been approved by State Bank of India, Punjab and Sind Bank, HDFC Bank, and Axis Bank. The project is ready to move.
Residents at Summit have access to a swimming pool, multi-purpose court, gymnasium, and indoor games room, among other amenities. The building also provides 24x7 security with CCTV, water softener systems, a walking track, rainwater harvesting, storm water drains, a sewage treatment plant, 24/7 power backup, and senior citizen sitouts.
Summit is not the developer's only reference point in this part of the city. Rustomjee Pinnacle, also in Borivali East and developed by Keystone Realtors Limited, launched in August 2017 and is now a ready-to-move project offering 2 BHK flats. Those apartments sit close to Borivali Railway Station, the Western Express Highway, and Sanjay Gandhi National Park. The Rustomjee name in this corridor therefore carries the weight of completed, occupied inventory — not just an address on a brochure.
Across its wider Mumbai network, notable Rustomjee projects include Rustomjee Elements, a large gated community in Upper Juhu; Rustomjee Paramount, a signature complex in Khar; Rustomjee Seasons, a 3.82-acre gated community in Bandra Annexe; and Rustomjee Crown, a 5.75-acre high-end development at Prabhadevi. The ability to deliver high-floor towers in a dense suburban micro-market like Rajendra Nagar reflects design and execution experience accumulated across these geographically varied MMR projects.
The choice of Rajendra Nagar — rather than the broader Borivali East label — is deliberate. The locality sits roughly 2 km from Sanjay Gandhi National Park, approximately 1 km from the Devipada Station on the Red Metro Line to Andheri, within 1 km of the Western Express Highway, and about 2 km from Borivali Station on the Western Line. That combination of rail, metro, and expressway access within a 2-km radius is uncommon even by Mumbai suburban standards.
With nearly 85 percent of construction completed, Mumbai Metro Line 9 is expected to begin operations by the end of 2025, linking Dahisar East to Mira Bhayandar. The Devipada Station on the existing Red Metro Line already brings Andheri's employment corridor within a single interchange. Forthcoming infrastructure, including the Coastal Road and the Thane-Borivali tunnel, is expected to further reduce travel time for working professionals.
Mindspace Malad and NESCO Goregaon IT parks are within 10 km of Rajendra Nagar, while Infinity IT Park and Techniplex Complex in Malad are approximately 9 km away. The neighbourhood is also within the vicinity of Suashish IT Park and Expound Technivo. This places Rustomjee Summit residents within a practical commute of the western suburban IT and commercial belt without residing in it — a meaningful quality-of-life distinction.
The neighbourhood around Summit includes healthcare centres such as Crystal Hospital and Dhanashri Hospital, and educational institutions including Rustomjee Cambridge International School and L.N. College. Dr Parikh's Maternity Gynaec and General Hospital, Navjivan Global Heart Centre, and Crystal Hospitals are among the prominent medical facilities in and around Rajendra Nagar. For retail, residents can access Raghuleela Mall, Inorbit Mall, and Growel's 101.
Average property rates in Borivali East stand at approximately Rs 29,200 per sq ft, with values having risen 11.7% over three years, 21.9% over five years, and 41.4% over ten years. Within Rajendra Nagar specifically, the average asking price for apartments is Rs 29,450 per sq ft. Property prices in Rajendra Nagar, Borivali increased by approximately 100% over the period 2016 to 2025.
Rustomjee Summit is cited as earning the highest annual rental yield among projects in Rajendra Nagar. Average monthly rental in Rajendra Nagar ranges from Rs 50,800 to Rs 88,400, with over 10 premium properties commanding rents above Rs 75,000 per month. The average rental yield in Borivali East is 3%. For buyers weighing the Summit as an investment asset alongside end-use, those rental figures are driven by the area's dual pull of metro connectivity and proximity to Sanjay Gandhi National Park — not by speculative demand alone.
