December 11, 2014 This $25M Glass Penthouse Sits Atop a Former Tribeca Factory By Zoe Rosenberg Easy on the eyes is the elegant $25 million penthouse of the converted dry goods warehouse at 7 Harrison Street in Tribeca, which is making its first non-rendering appearance in a newly released batch of photographs. The 4,229-square-foot duplex designed by class-act architect (and long-time 7 Harrison resident) Steven Harris takes a cue from Southern California style with its sweeping glass walls and sleek fittings. The 2,351-square-foot landscaped terrace with a reflecting pool wraps around the aparmtent's living floor and offers just enough cover from prying eyes. The penthouse is also being offered as a combination unit with the building's only remaining apartment, the half-floor 7N, for $34 million.
