In November 2025, King Charles III visited Fortnum & Mason in Piccadilly to officially open the landmark store's most significant structural change in a generation: a bespoke double helix staircase. Designed by Ben Pentreath Studio, the structure is an elegant intervention to improve movement between levels especially during peak times.

Fortnum & Mason is an upmarkert department store in the heart of London that was established in 1707. The iconic building we see today emerged from a major conversion in the 1920s.
During a visit several years ago in the lead-up to Christmas, I remember the previous staircase being beautiful but difficult to navigate. The sheer volume of shoppers led to a major chokepoint. With hundreds of thousands of visitors each December, the Fortnum's team were wise to look for a new solution and to launch it before the Christmas rush.
