In 1986, the Hiranandani group signed a tripartite agreement between the group, Maharashtra state and the MMRDA for developing 230 acres of land and for constructing affordable housing. The contract was signed at the rate of ₹0.40 (equivalent to ₹5.00 or 6.0¢ US in 2023) per acre. As per the contract, the real estate developer was to construct apartments measuring 430 ft and 861 ft (50% each) as "Medium Income Group Homes" (affordable housing).

Construction started in 1989 and the area then was barren and hilly. The area lacked basic infrastructure such as roads, sanitary sewer lines, water or electrical connections. Along with developing the basic infrastructure, more than 100,000 trees were also planted. By the early 1990s the first phase of apartments were ready and were initially sold at the rate of ₹500 (equivalent to ₹4,900 or US$58.70 in 2023) per ft. In the late 1990s, the construction and the architecture strategy was changed from "affordable" to upmarket housing and the neoclassical architecture was adapted as theme for upcoming buildings. By the mid 1990s, a shopping mall (Galleria) was constructed at the geographical center of the township.
