A spiral staircase is a type of staircase that features a circular design, with steps arranged around a central pole or column. This compact and elegant design allows for efficient use of space, making it ideal for areas where a traditional staircase may not fit. Spiral staircases can be made from various materials, such as wood, metal, or concrete, and are often used in residential homes, commercial buildings, and public spaces. Their aesthetic appeal adds a unique visual element to interiors, while also providing a functional way to connect different levels of a structure.
