Where possible, the designers say, whether it’s for the silver railings, crystal chandeliers, woven area rugs or steel support beams, the Ambanis are using Indian companies, contractors, craftsmen and materials firms. Elements of Indian culture juxtapose newer designs. For example, the sinks in a lounge extending off the entertainment level, which features a movie theater and wine room, are shaped like ginkgo leaves (native to India) with the stem extending to the faucet to guide the water into the basin.
On the health level, local plants decorate the outdoor patio near the swimming pool and yoga studio. The floor also features an ice room where residents and guests can escape the Mumbai heat to a small, cooled chamber dusted by man-made snow flurries.
For more temperate days, the family will enjoy a four-story open garden. In profile, the rebar-enforced beams form a “W” shape that supports the upper two-thirds of the building while creating an open-air atrium of gardens, flowers and lawns. Gardens, whether hanging hydroponic plants, or fixed trees, are a critical part of the building’s exterior adornment but also serve a purpose: The plants act as an energy-saving device by absorbing sunlight, thus deflecting it from the living spaces and making it easier to keep the interior cool in summer and warm in winter. An internal core space on the garden level contains entertaining rooms and balconies that clear the tree line and offer views of downtown Mumbai.
The top floors of entertaining space, where Ambani plans to host business guests (or just relax) offer panoramic views of the Arabian Sea.
