Spiral staircases are made very compact. Their main feature is the fact that treads ‘twist’ around a centre pole. They can be manufactured right or left turning with different numbers of steps per revolution. In terms of appearance, a spiral is never too dominating and so it complements modern and traditional décor.
Spiral staircases are valued for their compactness. They are very popular in places where space is at premium, e.g., loft conversions. They require the same small base no matter how high you need them.
