Renderings Revealed for 809 Madison Avenue’s Expansion on Manhattan’s Upper East Side
Renderings have been revealed for the expansion and residential reconfiguration of 809 Madison Avenue, a 12-story building on Manhattan’s Upper East Side. Designed by Robert A. M. Stern Architects and developed by Harry Macklowe of Macklowe Properties and SK Development, the project involves the addition of three floors above the existing roof, as well as a full renovation to convert its interiors into single-floor condominium units with an average scope of 4,000 square feet. The 159-foot-tall structure will also be expanded horizontally on its eastern elevation and will get new, larger windows. The roof-level addition will house a sprawling penthouse with a 1,500-square-foot private terrace. SLCE Architects is the architect of record for the property, which is located at the corner of Madison Avenue and East 68th Street.
