Dear PoPville – Thinking about Converting a Spiral Staircase

Dear PoPville,

I am thinking about possibly converting an existing spiral stair case to regular type staircase. Before I start calling companies I wanted to here from architect readers if it is possible to begin with.

The spiral stair case is in the middle of an open-floor first floor and it goes two levels. The floor to ceiling height between first and second floor is 103″. First floor ceiling to second-floor floor is 14″ thick. Second-floor level isn’t open floor plan so it has three walls surrounding the staircase. Second-floor floor to second-floor ceiling is 104″. Second-floor ceiling to third floor floor is 14″ thick.

The spiral staircase opening is 75″ by 75″ square for each floor level.

Is it possible to build a staircase that turns twice or three times on each floor?
