Subsequently, How much does it cost to build a curved staircase? A curved stair is the most expensive stair shape. Typically curved staircases start at about $9,000* and go well over $100,000 due to custom materials, styles and more complex engineering.
What is code for a spiral staircase?

You need at least 44”x44” opening because you’ll need two extra inches for your fingers to travel along the handrail as you walk up and down the stairs. The two extra inches ensures that there will be no finger pinch-points.
What is helicoidal staircase?
Helical staircases are fabricated to have the appearance of a curve or helix. This curved structure leads you from one level to the next by way of a flowing circular rotation. Because of its unique shape and rising characteristic, this type of staircase is ideal for retail, showrooms and atriums of public spaces.

Why you don’t want a spiral staircase?
This is because the narrow width purposefully constricts people, especially when in a clockwise orientation. This design, even though practical in a historical sense, will prevent them to be used in a living setting in a modern setting.
