U-Stair (Switchback Configuration)

U-Stair Overview

The U-stair is a switchback floating stair configuration engineered to reverse direction typically by 180° while preserving the minimal profile and structural efficiency of a mono-stringer system. The stair is composed of two runs that travel in opposite directions, connected through a defined turning element (most commonly a mid-landing, or alternatively a winder sequence). This arrangement shortens the required plan length, concentrates the transition at a controlled node, and can improve circulation by aligning entry and exit points within a compact footprint. When properly engineered, the turn and landing region provides a robust transfer of forces between runs with predictable stiffness and low deflection. The U-stair is a reliable solution for residential and commercial layouts that demand efficient use of space without sacrificing clean geometry or compatibility with a wide range of tread materials, finishes, and guard systems.
