Spiral stairs in Walnut with feature triple turned handrails
Our bespoke spiral stair designs are available in any diameter, from 1600mm up to 2500mm, for clockwise or anticlockwise rotation, in a square or round stair well. Solid Oak spiral stairs, Walnut spiral stairs or Stone spiral stairs with matching or contrasting balustrading in stainless steel or wrought iron, our spiral stairs cost from as little as £7,500 including installation.
Spiral stairs wind around a central newel or pole and typically have a handrail on the outer side only. A squared spiral stair has a square stairwell resulting in unequal steps (larger where they extend into a corner of the square) whereas a pure spiral assumes a circular stairwell and the steps and handrail are equal and positioned screw-symmetrically.
When planning your spiral staircase you may want to bear in mind that spiral stairs in medieval times were generally made of stone and typically wound in a clockwise direction from the ascender's point of view. This was to place attacking swordsmen, who were most often right-handed, at a disadvantage compared with the defender descending the spiral stairs in an anticlockwise direction. Existing 14th to 17th century examples of these spiral stairs can be seen at Muchalls Castle, Crathes Castle and Myres Castle in Scotland.
For that real wow factor, there really is nothing to compare with a Boss stone spiral staircase made by our multi award winning* stonemason.

As we have already discovered, spiral stairs wind around a central newel post, or pole, and typically have a handrail on the outer side only, whereas helical stairs, or circular stairs, do not have a central pole and, depending on the orientation, there can be a handrail on both sides.
Both spiral stairs and helical stairs are characterized by the number of turns that are made; a 'quarter-turn' stair deposits the person facing 90 degrees from the starting orientation. Likewise there are half-turn, three-quarters-turn and full-turn spiral stairs. A continuous spiral staircase may make many turns depending on the height. Very tall multi-turn spiral stairs are usually found in old stone towers within fortifications, churches and in lighthouses. Winder treads or 'Kites' are often incorporated into a straight staircase in order to turn the direction of the flight which allows for a greater number of permutations.
