A helical staircase is a type of staircase that features a spiral design, allowing it to ascend in a circular motion around a central axis. This design not only saves space but also adds an aesthetic appeal to both residential and commercial buildings. Helical staircases can be made from various materials, including wood, metal, and concrete, and they often have a smooth, continuous handrail. These staircases differ from traditional spiral staircases in that they do not have a central pole, providing a more open and elegant appearance. Helical staircases are commonly used in modern architecture and can be found in homes, offices, and public spaces, enhancing the overall design of the environment.
