Architectural Concept & Structural Design
A sculptural, minimalist staircase where thick solid-hardwood treads project straight out from a smooth plaster wall with no visible floor supports, encased in structural glass.
Structural Execution Guide
-
Conceal a heavy-duty 1/2-inch structural steel plate stringer inside the load-bearing wall studs before hanging drywall.
-
Weld structural steel box brackets perpendicular to the hidden stringer at each step interval.
-
Sleeve 3.5-inch thick solid rift-sawn oak box treads over the steel brackets, securing them with hidden underside fasteners.
-
Anchor 3/4-inch laminated structural glass balustrades into a continuous recessed floor shoe channel.
-
Embed a continuous warm-white LED ribbon beneath the lip of every floating tread to cast steps in a downward glow.

Pro Design Tip
Recess the base shoe holding the glass balustrade completely beneath the floorboards so the structural glass appears to rise seamlessly from the floor.
