One New Change is one of the oldest streets of the City of London, leading from St. Paul’s Cathedral to London Bridge. It is the historic location of the medieval high street and market. Designed by Jean Nouvel and opened in 2010, One New Change is a major office and retail development at the corner facing St. Paul’s Cathedral that seeks to bring leisure and retail uses back to the banking quarter of the City

The stair at One New Change is intended to be a sculptural feature in the public space facing St. Paul’s, and to drastically improve the pedestrian circulation between the lower, public levels of the project.

The curved glass balustrade is treated with a fading mirror frit, transitioning from fully mirrored to fully transparent, giving the illusion of people floating down the stair. The soffit of the stair is made from 3-dimensionally curved mirror polished stainless steel, creating a warped perspective of its form that seems to disappear. In order to use the rain cover created by the new stair, the handrail has been designed to extend beyond the stair and turn into a bench, creating sheltered seating and a new meeting point. Special attention was paid to preserve continuous lines and surfaces, in order to make the staircase merge smoothly, effortlessly, harmoniously with the context.
