The living room fireplace was constructed of board-formed concrete (which imprints a woodgrain texture into the concrete) instead of traditional brick or stone. It features a ten-foot-tall center glass panel that was patina’d using a silvering technique to create an iridescent bronze finish with vertical streaking. The entrance to the master bedroom features a six-foot-tall onyx stone with a natural edge, mounted and recessed into the wall. Two custom metal stairways use reclaimed wood treads from a linden tree sourced on site. A tile mosaic in the basement bath pays homage to the decorative subway tile of New York and the homeowner’s home town of Brooklyn.
