A feasibility study was undertaken with the owner and it was determined that it would be necessary to increase the usable area of the building by 50 percent to realize the income to justify the cost of development. Accordingly, the mezzanine structure was removed and a full third level was inserted into the building by adapting and reinforcing the existing structure. All existing building systems were replaced with new energy efficient systems, including HVAC, electrical, lighting, plumbing and fire protection. To comply with the current energy code and mandates of the State of New York, careful attention was given to improving the building envelope to be more efficient. This included insulating the exterior walls and roof, along with adding an interior secondary glazing system to the restored original wood windows. All requirements for ADA compliance were provided, such as a separate accessible entrance and a new elevator serving the new two story lobby, which includes the restored original main stairway at the front entrance. Many original elements that were removed were carefully reconfigured and reused in new locations to maintain the original character of the building to the greatest extent possible. The exterior restoration of the building included masonry cleaning and tuckpointing, stone trim repair, window restoration and roof replacement.
