Keystone Realtors Limited, which sells under the Rustomjee brand, was incorporated in 1995 and is headquartered at Natraj, Western Express Highway, Andheri East, Mumbai. Incorporated in 1995, Keystone Realtors Limited is one of the prominent real estate developers, and the company is a prominent MMR-based real estate developer and a leader in the redevelopment space. Over three decades, the company built its name on Mumbai and Thane addresses rather than hill-station product, which is what makes its recent shift toward plotted, land-based developments in the Sahyadri corridor worth tracking for anyone evaluating Lonavala as a Rustomjee-adjacent market.
In September 2024, Rustomjee Group announced its first plotted-development project, Belle Vie, in Kasara near Igatpuri. A gated community spanning 88 acres, Belle Vie introduces 462 meticulously designed villa plots, ranging from 2000 to 7000 square feet, with prices starting at INR 59 Lakhs. The company explicitly framed the move around land as an asset class for weekend and second-home buyers. Chairman and MD Boman Irani said, "At Rustomjee, we recognize the rewarding potential of land investment, particularly in terms of high appreciation and" long-term value for buyers seeking a retreat within driving distance of Mumbai. Kasara sits on the same Mumbai-hinterland leisure axis as Lonavala, and the same investment logic — a supply-constrained hill setting, gated infrastructure, and NRI or HNI weekend demand — is the one that has made Lonavala one of Maharashtra's most established second-home markets. For a developer that has spent most of its history on urban apartments and townships, Belle Vie signals that plotted, nature-facing product in this belt is now a category Rustomjee is actively building expertise in, which is directly relevant to how the brand is likely to approach a market like Lonavala.
Rustomjee's core business remains dense urban and suburban Mumbai. The company has a diversified suite of projects across a wide range of price points having developed 20.2 mn sq ft of high-value and affordable residential buildings, premium gated estates, townships and various other projects. Its flagship township, Rustomjee Urbania in Thane's Majiwada, illustrates the scale the group operates at away from central Mumbai. Spread over 100+ acre, Rustomjee Urbania is a spacious residential property in Thane, featuring 2 and 3 bedroom flats, and is a self-sufficient township with modern living spaces, its own school, commercial complex, retail and entertainment centres, sports clubs and more. The company has also pushed into ultra-premium single-tower addresses such as Prabhadevi's Rustomjee Crown and a newer Thane luxury project, Verdant Vistas, developed with Singapore's Keppel. The Verdant Vistas project is anticipated to comprise 440 units with a gross development value of Rs.1,750 crore, marking Rustomjee's debut luxury project in Thane, with 3BHK units from 1,100 to 1,300 square feet and 4BHK units between 1,750 and 2,250 square feet. This range — from large integrated townships to single luxury towers to, now, gated plotted land — is the same toolkit a developer would draw on to build a leisure-home product in Lonavala.
Keystone Realtors listed on the stock exchanges in November 2022, and its scale has continued to grow since. The company had already sold properties worth Rs 1,839 crore in the first half of 2025-26, up 40 per cent annually, and bagged three redevelopment projects in Mumbai during the June quarter with a revenue potential of more than Rs 7,700 crore. Chairman and Managing Director Boman Irani has also flagged ambitions beyond the existing Mumbai-Thane base. Keystone Realtors plans to launch a super luxury residential project in Mumbai with a revenue potential of about Rs 3,000 crore, with the company, which sells properties under the Rustomjee brand, counted among the country's leading real estate developers. This balance sheet strength and pipeline discipline is the backdrop against which any Rustomjee move into a leisure-home market such as Lonavala should be read — a listed, cash-generating developer extending a proven Mumbai brand into a category it has only recently entered.
Lonavala's appeal rests on a market that has already matured around one structural driver. Lonavala's growth has been driven almost entirely by road connectivity via the Mumbai-Pune Expressway and the Old Mumbai-Pune Highway, and the market has a 15-plus-year track record of appreciation with an established rental base. The Mumbai-Pune Expressway, opened in 2002, keeps improving: the Missing Link tunnel near Lonavala is at an advanced stage of completion and will cut another 20–25 minutes off the drive once operational. Rail access adds a second, lower-cost connectivity layer, since Lonavala Railway Station provides an easy commute to the top nearby cities such as Pune and Mumbai. On pricing, the town sits well above the newer peripheral hubs along the same corridor. Average prices in Lonavala stand near ₹12,583 per sq. ft., with premium villa zones commanding higher rates. Independent commentary on the wider expressway corridor places Lonavala at the top of the demand curve: Lonavala operates at the premium end, with villa communities and plotted developments drawing HNI and NRI buyers seeking capital preservation in a supply-constrained setting.
Within Lonavala, demand concentrates in a handful of named pockets rather than being spread evenly across the town. Top areas include Khandala for luxury, Tungarli for villas, Kune for gated developments, and Malavli for budget-friendly investments with strong long-term appreciation potential. The buyer base is dominated by second-home purchasers rather than end-users relocating permanently. Lonavala's property prices are mainly influenced by second-home buyers and demand for vacation rentals, thanks to its scenic environment and weekend appeal. Land scarcity in the established core is part of the pricing story: prime central neighborhoods now have almost no land available for safe purchase, and this extreme scarcity naturally drives up the value of heritage estates and private bungalows. That scarcity, combined with a gated, professionally managed alternative to fragmented private plots, is the same gap that a branded, listed developer's plotted or villa product is designed to fill — the template Rustomjee has already tested at Belle Vie in Kasara.
There is no ambiguity about where Rustomjee's delivered projects currently stand — Mumbai, Thane, and, for plotted land, Kasara near Igatpuri. Lonavala sits within the same Mumbai-Pune leisure corridor that the group has identified as a growth category, and the town's mature connectivity, established rental market, and constrained land supply mirror the conditions the company cited when entering Kasara. For a prospective buyer, the relevant takeaway is less about a specific address and more about the brand's demonstrated direction: an MMR-anchored, listed developer with over two decades of delivery experience is actively building a plotted and leisure-home vertical in exactly this kind of hill-station market.
