A spiral staircase is a type of staircase that winds around a central column, creating a circular or helical shape. This design allows for efficient use of space, making it ideal for small areas where traditional staircases may not fit. Spiral staircases can be made from various materials, including wood, metal, and concrete, and they often feature open risers for a modern look. These staircases are commonly found in both residential and commercial buildings, providing access to different levels. They can also serve as decorative elements, enhancing the aesthetic appeal of a space. Architects often incorporate spiral staircases into their designs for both functionality and style.
