Spiraling Down

Categories: Renovation

I built a 60 sq. ft. loft in my studio on the parlor floor of a brownstone in Park Slope. The loft is mainly supported by a spiral staircase in the center, and the co-op is concerned about having so much weight concentrated on such a small area. What are general tolerance levels for brownstone floors? Does anyone know an engineer who could look at it?
