The detail on the thick, black columns were custom-cut dowels, hand painted and varnished with polyurethane.
The white brick wall was also laser cut and scored. Thin, watery layers of white acrylic were applied multiple times to avoid obscuring the shallow scoring.
The plaster portion of the fireplace was fabricated from layers of MDF board glued down and cut down with a table saw. The side detail was achieved through CNC routing.
