Rustomjee Doubles Down on Mumbai Redevelopment: 78% of New Projects

On 14 November 2026, Boman Irani, chairman and managing director of Keystone Realtors Limited, which sells under the Rustomjee brand, said redevelopment now makes up 78% of the projects the company has added since FY23. Of the 27 projects added in that period, 21 are redevelopment schemes, and 23 serve luxury, super-premium, premium or emerging premium buyers. Their estimated gross development value comes to Rs 31,079 crore. Irani said the company will deepen its focus on redevelopment in Mumbai, and the figures show that the shift is already well under way.

The half-year numbers for H1 FY27 back up the change. Presales reached Rs 2,041 crore, up 11% from Rs 1,839 crore in the same period last year. Of that, Rs 1,900 crore (93%) came from sales at existing projects, while the Goregaon West project Ozone Skye contributed Rs 140 crore. Collections stood at Rs 1,141 crore, and management expects FY27 collections of Rs 3,000 crore to Rs 3,100 crore. Spending on land and approvals rose to Rs 425 crore from Rs 302 crore, a jump of 41%.

Looking ahead, the company expects roughly Rs 8,000 crore of launches in the first nine months of FY27, covering eight projects and 5.2 million square feet. Its FY27 launch plan names GTB Nagar, Avinash Tower, two towers in Thane and a tower in Dombivli. Management has moved Dindoshi and Om Nagar to H1 FY28, but still expects the FY27 launch target to be met through the other four.

Impact on Homebuyers

For a buyer, the first thing to understand is that redevelopment projects run on a different clock from ground-up towers. A scheme depends on society consents, municipal sanctions and sometimes a long wait for the old tenants to be rehoused, so possession dates can move. Irani himself called redevelopment a business with "plenty of risks" that still looks "very attractive". He said the company's own exposure is limited because it sells about 35% of the stock in the first year and about 40% more as the project continues, which gives it room to absorb rising costs.

Costs are the part buyers should watch closely. Irani put the cost increase in the region at about 8% to 13%. When construction and approval costs climb by that much, developers tend to pass some of it on, so buyers in the affected micro-markets should expect new launches to be priced with that pressure in mind. In our view, this is more likely to show up in the price of fresh launches than in resale values already locked in.

Before booking any redevelopment home in Mumbai, check the RERA registration, the registered possession date and the title chain. Ask for the society conveyance status as well. Where the land title or the society's paperwork is still unsettled, the timeline can stretch well beyond what the brochure suggests. Buyers who can wait for a clear approval trail may find the wait worth it, while buyers who need a home by a fixed date should look at projects that are already well advanced.

Expert Analysis

The move toward redevelopment makes sense when you look at the size of the opportunity. Irani has said Mumbai redevelopment opportunities worth nearly Rs 1.30 lakh crore are expected by 2030. Earlier this year on an earnings call he explained the logic plainly: the company is moving toward larger schemes because they give its teams more room to apply their design and planning skills. Bigger schemes also spread approval and construction effort over more homes, which helps a developer that wants to keep its pipeline full.

The business model behind this push is asset-light. Keystone Realtors says it underwrites new projects at around 35% gross margins and caps upfront equity at about 10% of project GDV. That approach lets the company take on more projects with less of its own capital, though it also means the pipeline depends heavily on sales and approvals going to plan.

The record gives some context. FY26 presales were about Rs 4,022 crore, up roughly 33%, the best annual figure in the company's listed history. At the same time, net profit in the fourth quarter of FY26 fell about 19% to around Rs 52 crore. Strong sales with softer quarterly profit is a combination buyers and investors should keep in mind as the company leans further into redevelopment.

What to Expect Next

The next few months will show whether the launch pipeline holds. The FY27 launches at GTB Nagar, Avinash Tower, the Thane towers and the Dombivli tower will be the first real test of the strategy, and the H1 FY28 timing for Dindoshi and Om Nagar will show how the schedule holds. Infrastructure should help over time. The developer's marketing points to the 12.2 km Goregaon–Mulund Link Road, targeted for completion by 2028, and the Versova–Dahisar Coastal Road, which is also expected to serve the western suburbs. Improved road links usually support demand in the corridors they serve, though buyers should judge projects on their own approvals and delivery records.
