If you’re a fan of concrete as a rich interior material, this just-listed West Soho will definitely impress. The 4,000-square-foot duplex is decked out with concrete columns, floors, and ceilings. This industrial chic space also offers a flexible floor plan, with a 30-foot-wide and 68-foot-long great room that allows for a number of configurations. Currently, it’s set up as a two-bedroom home with a studio art space and a casual media lounge. The creative, well-designed residence is located within the 18-unit condo at 481 Greenwich Street, and is now asking $5.25 million.
