A helical staircase, also known as a spiral staircase, is an architectural feature that consists of a continuous flight of steps that wind around a central pole or core. The design allows for efficient use of space and can add a unique aesthetic to any area it's installed in. These stairs are often found in homes, offices, and other buildings where space is at a premium. With their distinctive look, spiral staircases can make a bold statement and become a focal point in a room.
