Half-Turn Single-Flight Stair — Layout variation
Category: Layout variation
Straight flight with a 180-degree turn in the middle.
A half-turn single-flight stair runs straight at the top and bottom and turns 180 degrees in the middle. This creates a direction change without requiring a separate intermediate landing. The winder treads in the turn must comply with the minimum going at the walking line.
