This spiral staircase was built on-site with all parts made in our shop then tranferred to the site. The first step was to make helical stringers which were then transported and installed on-site. The main newel posts, treads and hand rails are quarter sawn white maple. The spiral weave balustrade is select white maple. The intermediate newel posts are bronze. The risers and skirts were made from paint grade materials.
Dimensions: The stairs wind up through 3 floors.
