Construction is moving along quickly on the triangular site at 606 Broadway, which is distinct for two reasons. The first is the unusual shape for a six-story commercial building. The second is that new non-residential buildings aren’t too common for Manhattan’s SoHo neighborhood due to landmark restrictions and generally astronomical property values, and this building is going to be entirely commercial. Retail will populate the cellar, first floor, and second, while offices will occupy floors three through six.
