A sizable area of Beverly Hills, Los Angeles, is set to turn green – literally – thanks to a new plant and tree-filled development designed by Foster  Partners.

Assuming all goes to plan, the project will create two new residential towers and a hotel, and will feature sustainable design, including extensive greywater recycling to meet its considerable irrigation needs.

The project, named One Beverly Hills, is being created in collaboration with Gensler, landscape architect Mark Rios, and developers Alagem Capital Group and Cain International. It will be located on a 17.5 acre (roughly 7 hectare) site currently home to the Waldorf Astoria Beverly Hills and Beverly Hilton hotels.

The existing hotels will be integrated into the new development, which will add an “ultra-luxury hotel,” two greenery-covered residential high-rise towers containing 303 residences in total, and a pavilion with retail and dining space.

There will also be 4.5 acres (1.2 hectares) of publicly accessible botanical gardens and sculpture gardens, with pathways and extensive landscapingover 300 species of plants and trees will be planted.
