Last month Kristina Fong provided an entertaining tour of the latest works by Herzog & de Meuron, architects of the Walker’s 2005 expansion. Now we can add one more stop: On the heels of a spectacular performance by their “Bird’s Nest” stadium at the Beijing Olympics, the Swiss team has revealed the design for a new building in Manhattan’s Tribeca neighborhood. Moving from a globally scaled gathering space to this project - the firm’s first residential tower - represents quite a shift in scale. But with its series of glass boxes cantilevered one over another, stacked to reach 57 stories, the building promises drama of a different order.
