Staircase at One & Five Bank Street

Simon Groves, a senior associate in our London office, discusses the unique asymmetrical staircase at One Bank Street in London. The 700,000 square foot office tower at Canary Wharf was designed by Kohn Pederson Fox with Adamson Associates (International) Limited as Executive Architect. Interiors were provided by TP Bennett.

TP Bennett produced the initial design concepts for the staircase. “We originally worked up the design as a spiral,” explained Andrew McLean. “But we have a designer who’s very interested in the geometry of stairs and he produced a more interesting ‘ribbon’ design.” The refinement of that SketchUp concept was carried out by Adamson Architects who developed the detailed design in close collaboration with EStairs Eastborne team.

Asymmetrical Ribbon Staircase at One Bank Street London

“I wanted to create a staircase that had a pure form,” said Simon Groves, a senior associate at Adamson. “Simplifying the ribbons of the inner and outer balustrade enclosures, and raising them to 1900mm, with no unnecessary undulation at the landings between the stair flights was key. This meant there were no stop-start points in the balustrades, just a pure form.”
