Regarded as a critically important early New York City skyscraper, this work of the renowned architect Ernest Flagg presented unique preservation problems. The exterior building system employs an exposed iron lattice to support terra cotta fireproofing over the structural steel skeleton. The restoration project called for much of the original lattice system to be removed in order to stabilize the terra cotta and allow for repair the underlying structural steel frame. The work included the fabrication of wrought iron components to replace damaged or missing ornamental pieces, the replication of the original glass and iron canopy at the Broadway storefront, the restoration of the operable mahogany and glass doors and transom windows, and the installation of a comprehensive roof level waterproofing system. In addition to the exterior restoration, Bone/Levine Architects also directed the work with NYC Planning Commission to allow for the change of use from commercial to residential use, and developed and executed a comprehensive infrastructure upgrading program that included a new residential entrance and lobby, elevators and building-wide mechanical systems to accommodate the new era of occupancy.
