Stair detail of a ground-up new construction home in the Berkeley Hills, CA, as featured on America ByDesign on CBS. The switchback floating stair is photographed from below revealing the full three-dimensional geometry of the white steel stringer structure - oak laminated veneer lumber treads cantilevered at each level, the open-riser design allowing light and views to pass through the stair volume from every angle. Glass panel railing with white steel balustrade wraps both runs of the switchback, creating a transparent enclosure that preserves sightlines through the double-height space. Behind the lower glass enclosure wall, a built-in wood slat wine rack is visible alongside the lush indoor garden planting of tropical ferns and ground cover in a river rock gravel bed.
