Stair and Handrail Design in Interior Spaces: A Comprehensive Guide

Stair design combines safe circulation, spatial planning, structure and guarding. Straight, quarter-turn, half-turn and spiral arrangements must suit space, use, and applicable escape and accessibility requirements.
Dimensions and layout
Check risers, treads, landings, headroom, handrails and guarding openings against the local code and building type. Dimensions from one jurisdiction or stair category cannot be applied universally, nor can an unsupported exception be made for a step.
Materials and details
Timber, metal, concrete and glass require an appropriately designed and supported system. Review slip resistance, visibility, lighting, connections and maintenance. Floating appearance, a manufacturer's name or market share does not establish design safety.
