The original staircase of this home was removed and replaced with a floating central staircase of thick, maple steps supported on a black steel frame anchored by a column paneled with Afrormosia wood. A built-in wine cooler is hidden behind the column. Sleek, brushed stainless steel railings complete the look. All the floors throughout the home are made of the same light maple wood for a cool, modern feel. Photos by Johan Roetz.
