Whether you are looking for a staircase as part of a new build project or as part of the renovation of an existing building, you will need to comply with the UK Building Regulations.
It is, of course, advisable to get expert advice on how your plans might need to be adjusted to meet all current standards. However, in general terms, the minimum going should be 220mm, whilst the pitch of the staircase should not exceed 42°. There are no restrictions when it comes to width, but standard flights measure 860mm, and for the main staircase it is agreed that a width of between 800mm and 900mm works best.
As long as the minimum standards for the size, safety, type and location of your staircase are being met, you will find there are many design options and choices of construction material to consider.
Make it your own. Make it unique. Make it a work of art.
