A helical staircase is a type of staircase that features a smooth, continuous design without a central column, allowing the steps to spiral outward in a gentle curve. This design provides a graceful and open appearance, making it a striking architectural feature in both residential and commercial spaces. Helical staircases can be made from various materials, including wood, metal, or concrete, and are often used to create a modern and elegant look. Their design maximizes space while providing a functional way to connect different levels of a building, offering both aesthetic appeal and ease of movement.
