The Terrace floating stairway, Viewrail’s newest stair system, uses a rigid steel stringer system concealed inside a series of stacked wood boxes to create a modern, “waterfall”-style stair with no visible fasteners or means of support. Tempered-glass railing panels, which appear to “slice” through the wood steps, flank both sides of the stair. The wood components are available in 15 species, either unfinished or in the customer’s choice of wood stains and colors. Pricing ranges from $11,000 to $19,000 for the complete system. viewrail.com
