Urban growth: bio-bricks offer a whiff of the future
A sweeping tower made from over 10,000 bio-waste bricks bound with fungal fibre has been growing in the courtyard of MoMA PS1, an offshoot of the Museum of Modern
Art (MoMA) in New York. Looking like something between a three-headed grain silo, Zhang Huan's Three Legged Buddha and a Berlin flak tower, Hy-Fi is the winner of this year's MoMA PS1 Young Architects Program (YAP), and its organic aesthetic clashes hard with the museum's red-brick frontage and the green-glass Citicorp building behind.
The bio-bricks used in Hy-Fi can be grown in five days
