90° Winding Stairs

Set of dimensioned drawings of 90° Winding Stairs with measurements for height and width

A 90° Winding Staircase makes a 90° turn up towards the next level. The staircase allows the user to turn a corner and change their direction. The primary benefit of a 90° Winding Staircase over a flat landing straight staircase is that the 90° Winding Staircase saves much more space. The winders are the steps that are narrower on one side than the other, and when three steps are used to turn the 90° corner, the middle step is called the kite winder, as it looks like a kite-shaped quadrilateral.

Stairs, stairways, staircases, or stairwells, are building components that provide users with a means of vertical movement with the distribution of separate and individual vertical steps. In buildings, a flight of stairs refers to a complete series of steps that connects between two distinct floors.
