subject: How Spiral Staircases Came About [print this page] A spiral staircase is a flight of steps with a central pole or post in which stairs are set out in a spiral. Spiral staircases have had many uses, and are often the center of visual interest in many homes. They were created hundreds of years ago as a way to bridge vertical gaps in a confined space. The spiral staircase, like many other modern architectural features, has had their place in modern construction and architectural history.
The spiral staircase came into common use sometime during the middle ages as a way to reach the top of towers, often kept inside castle walls. Spiral stairs in medieval times were generally made of stone. They were typically wound in a clockwise direction from the ascenders point of view, in order to place attacking swordsmen who were most often right-handed, at a tactical disadvantage.
As the stairs progress up the pole in a screw-like, helical pattern, elevation is achieved. This asymmetry forced the right-handed swordsman to engage the central pike, giving the defender the advantage in single file combat.
Today, spiral stairs are no longer used for their military advantage. A typical exterior spiral staircase will often make efficient use of areas in smaller homes and condominiums, thereby maximizing floor space. Exterior spiral staircases can be used to provide access to a second floor terrace or viewing loft, without taking too much space from the pool area or the garden.
Many modern designs have allowed home owners and manufacturers to construct an exterior spiral staircase from almost any known construction material. Many prefer metal staircases such as those made from cast iron or steel, while others prefer the classic look of wood.
Manufacturers have even created a starter kit for DIY enthusiasts. These custom spiral stairs can be built on the spot, right out of the box so to speak, with the manufacturers providing all the necessary components for either a metal spiral staircase or a wooden spiral staircase. Kits are considered an easy and cost-effective means of building a spiral staircase, but only if the home owner has at least some experience in construction and tools usage.
