One Madison Avenue’s New Glass Curtain Wall Begins Installation in Flatiron District, Manhattan
The new glass curtain wall has begun installation on One Madison Avenue, a 27-story commercial building in the Flatiron District. Designed by Kohn Pedersen Fox and developed by SL Green, the National Pension Service of Korea, and Hines, the project involves the gut renovation of an eight-story structure and the construction of a new steel-framed addition above its parapet, and will yield 1.4 million square feet of office space and ground-floor retail. NYC Constructors is building the expansion and AECOM Tishman is the construction manager for the property, which occupies a full block at the southeast corner of Madison Square Park between Madison Avenue, Park Avenue South, East 23rd and 24th Streets.
The superstructure of the addition had recently topped out at the time of YIMBY’s last update in December and crews were in the process of fireproofing the steel beams. Since then, more steel members have been assembled around the mechanical roof bulkheads and additional decking was laid for the top office floors. Work has now shifted to the installation of the glass façade on the lower stories of the expansion.
