Mumbai, April 10 -- Over 100 acres of land in Andheri West around Gilbert Hill, a 66-million-year-old monolith, are set to be transformed under the Maharashtra government's recently introduced slum cluster redevelopment scheme. The 101.36-acre land parcel, stretching from Juhu Galli (CD Barfiwala Road) to the backyard of the Hansraj Morarji Public School, currently houses nearly 14,000 hutments and several residential buildings, officials from the Slum Rehabilitation Authority (SRA) said. According to the bid document, a copy of which is with HT, the project will be executed under a construction-and-development agreement model, in which the state government receives a share of the housing stock and existing inhabitants are rehabilitated on-site. The appointed developer will have to construct 561 tenements measuring 300 sq ft each for the existing inhabitants, subject to clearance from the Brihanmumbai Municipal Corporation (BMC). The developer will also be allowed to sell a certain percentage of the apartments in the open market. "The project's primary objective is to improve the living standards of residents of the cluster by transforming the area into a well-planned integrated development as per the provisions of DCPR 33(10) and other relevant regulations, including under the slum cluster redevelopment scheme approved in November 2025," said an SRA official. According to the Request for Qualification-cum-Request For Proposal document floated by the SRA, the developer will be appointed based on the percentage of the ready reckoner rate for land that the company is willing to pay as a premium to the SRA. The minimum threshold has been set at 10%. Real estate companies with a minimum consolidated net worth of Rs.25,000 crore are eligible to bid. According to SRA officials, there are 13,634 hutments and several non-slum buildings on the land parcel. This includes previously constructed SRA projects, a private hospital, a police station, a civic market, a retail market, educational institutions, and government offices. The developer will have to survey existing structures to finalise eligibility for rehabilitation. The developer must also deposit Rs.1,050 crore with the SRA towards three years of transit rent, calculated at Rs.20,000 per month per tenement. Slum residents will have to pay a one-time shifting charge of Rs.15,000....
