H2I3T

Construction is underway, albeit with some delays, on one of India’s highest profile and most opulent projects—the Antilia, a 490-foot-tall corporate meeting facility and private residence in Mumbai. Chicago-based Perkins + Will designed the 24-story tower for business tycoon Mukesh Ambani, whose family will occupy roughly 35,000 square feet in its top floors.

Among its interesting elements, Antilia will feature a band of vertical and horizontal gardens that demarcates the tower’s different program elements. A garden level will separate the ground-floor parking and conference center from residential space above, for instance, and the outer walls on certain levels will be sheltered by trellises supporting panels that contain hydroponically grown plants.

In addition to signaling different space uses and providing privacy, these “vertical gardens” will help shade the building and reduce the urban heat island effect. “You can use the whole wall almost like a tree and increase the green area of the site by five or 10 times over what it would be if you just did a green roof,” Johnson observers. “It’s a prototype for buildings of the future.”
