Landing Stair — Layout variation

A landing stair consists of two or more straight flights connected by one or more intermediate landings. The landing itself carries the change in direction – typical plans are the L-shape (quarter-landing stair, 90-degree turn) and the U-shape (half-landing stair, 180-degree turn). This clearly sets the landing stair apart from winder stairs, where the direction change is made by tapered winder treads. Per DIN 18065 a landing is mandatory after at most 18 rises; in practice it also offers a resting and passing area, which greatly improves walking comfort on long flights. Structurally, a landing stair can be built in virtually any construction type – as a housed-string stair, cut-string stair, folded-plate stair or as a hybrid. The landing is usually framed as a load-bearing structure with an infill panel and is tied into the strings or bolts. Aesthetically, landing stairs allow for representative entrances, especially when the landing is made wider than the flights or highlighted with a contrasting floor finish. Due to the additional string joints, landing framing and handrail detailing, landing stairs are typically priced above single-flight straight stairs. Typical applications include older buildings with high storey heights, generous new builds with sufficient floor area, and projects where DIN compliance and high walking comfort are key priorities.
