EXHIBIT, at 56 Fulton Street, will be a 23-story rental tower in the heart of the rejuvenated Financial District. The 130,000-square-foot project replaces a large, preexisting parking garage and is being developed by the Brauser Group and Scott Aaron's Socius Development Group. Hill West, the building's architects, have specified a conservative exterior composed of dark-colored bricks, multi-pane windows and floor-to-ceiling windows. The fast-rising project was topped off this fall and has already received most of its cladding. At this rate, leasing should begin by year's end.
