Moscow to get Green Giant

Foster and Partners unveil world's tallest naturally ventilated building

Taller than any other building in Europe – Foster's new tower for CTT Group will be a striking new addition to the dynamic high-rise skyline of Moscow City. The mixed-use project - incorporating apartments, hotel, office and leisure space - will have an ‘energy cycle’ that will help promote sustainable design globally. At ground level, an inverted pyramid that houses retail space and a public ice-rink With retail and offices generating higher density use towards the base – residential, hotel and serviced apartments are located in the higher end of the building, there are a series of green skygardens that draw in natural ventilation and provide key circulation and social space. At the summit, a publicly accessible viewing deck with cafes and bars creates a magnetic new attraction for both visitors and residents of Moscow.
