Obsidian Stairs - Kadenwood

Obsidian Stairs is a two-storey feature stair engineered with a central scissor stringer and plate stringers, anchored by a solid steel node at the mid-height landing. The landing is supported by a tension tie composed of steel and aluminum pickets, creating a visually light yet structurally robust system. R+A worked closely with the One Sixty Fourth Design to provide specialty engineering services, ensuring the stair maintained clean lines, transparency, and precise performance while serving as a sculptural centerpiece of the space.
