One of the most common questions we get asked is “where does the spiral start and finish”. The rotation of a spiral staircase is determined by:
The floor to floor height (which specifies the number of treads)
The diameter of the spiral (smaller diameters generally have a larger tread segments)
The shape and size of the top platform
Building regulations (they stipulate a minimum tread depth (going) and maximum height (riser) of each step.
