A spiral staircase is one that turns or curves around a solid or open central axis. In a contemporary home, it is often a sculptural highlight that serves as an architectural connector across floors. The spiral staircase is the perfect addition in compact areas; it can also make an impression in larger spaces. The versatile nature of a spiral staircase renders it ideal for duplexes and storied properties: there is a great deal of flexibility in terms of its placement. The materials used in making spiral staircases will vary depending on the context. They include: concrete, glass, steel, tiles, and wood. A handrail is optional, but may in fact form an integral part of the structure.
Spiral staircases come in varied shapes and sizes. However, to truly make an entrance, the dramatic spiral staircase is a must-have, as shown in these examples.
