It’s rare to find an historic apartment building in TriBeCa that hasn’t yet been topped off by a modern penthouse – in this Lower Manhattan neighbourhood where space is at a premium, a bird’s eye view will reveal a five-storey ‘townhouse in the sky’; an extension with folded metal roof by WorkAc, hidden from sight from passers-by on Reade St; and even a penthouse with retractable glass walls by Praemium Imperiale-prize winner Shigeru Ban.
