C3D Architecture’s 989 Sixth Avenue integrates curved, overlapping curtain wall assemblies with advanced fire and mechanical systems

At the corner of Sixth Avenue and West 37th Street, in Manhattan’s Garment District, a new tower is taking shape. Designed by C3D Architecture and developed by SIONI Group, 989 Sixth Avenue is now visible on the skyline between Bryant Park and the Empire State Building. At the street level, the building’s podium adjoins the classic, revival-style Greenwich Savings Bank Building—better known as the Haier Building—a 1922 York & Sawyer landmark of Indiana limestone, bronze, and granite. Above, the tower extends upward as a composition of layered, curved extrusions.
