Designed by Studio Nicoletti Associati, these unusual, onion-shaped towers are designed for Precinct 4, or the Putrajaya waterfront in Malaysia (30 kilometers south of Kuala Kumpur). The architect was inspired by ship sails and traditional Islamic architecture. The towers are efficient and green: they are permeable structures with terraces, sunshades, natural ventilation and integrated green space. The towers will also make use of renewable power, and are expected to produce 50% less CO2 emissions than similar residential projects.
