This spectacular Cantilevered Helical Staircase over 5 floors was commissioned by developers for an elegant period house that was totally re-constructed in the heart of St John’s Wood and will be one of the most outstanding properties to come on the market this year. The steel carriage was clad in fine white satin marble with a plastered soffit. The bespoke balustrade was specially designed, individually hand crafted and finished in a dark metallic bronze paint. The handrail was a flat oval section in American Walnut with an oiled finish.
