This muscular, massive 6,250 square foot duplex penthouse loft has one of the largest footprints of any penthouse downtown and boasts enormous proportions, soaring ceilings, fantastic finishes and four exposures. The lower level features roughly 3,000 square feet of open living/dining space with spectacular north views, plus a media room and 3 full bedrooms. The upper level features a large indoor entertainment area and a dramatic master suite, opening onto a park-like wrap terrace. 540 square feet of buildable air rights also remain, which could potentially be added to the roof. The low key building, converted to full floor condos in 2001, features a key-locked elevator which opens directly into the unit and also allows direct access to the terrace.
