One of New York’s oldest cast-iron façade buildings, the Cary Building is a beautiful landmarked structure located at 105 Chambers Street. This five-story landmarked building, erected in 1857, has been largely preserved in its original state with interior alterations accommodating use for commercial, office and residential occupants. The façade elements and envelope had received very little attention until a new owner decided to invest in the building in 2004. Murray Engineering has continued to provide long-term engineering evaluation and design to alterations in this historic building. Our work has included the forensic study of the original building assembly and materials, coordination of façade restoration with the New York City Landmarks Commission and Department of Buildings and the design of the support structure for a rooftop pool.
