Atop 12 East 13th Street is a gently canted three-story curtain wall that provides the setting for one of the most spectacular residences in the City. Conceived as a glass-enclosed volume, the 5,700 square foot triplex penthouse is an atelier of light. A sculptural, soaring wood and glass open stair connects the three levels, crossing the space against the sky. The vast 3-story interior encompasses four bedrooms and four and a half bathrooms, and includes a formal dining room, a family room, and a private sauna. Two gracious terraces for outdoor living, each on a different level, can be accessed by your private elevator. Two private, on-site parking spaces are also included in the sale.
