Fortnum & Mason has opened a stunning double helix staircase in its flagship London store.

The staircase, which has been two years in the making, was installed to improve shopper flow through the landmark Piccadilly shop as well as to create a dramatic feature in keeping with the iconic department store’s architecture.

There are only a few such staircases in the world. The staircase is formed of two spiral stairways. They appear as a single structure in the centre of the building’s atrium, “like twisting strands of DNA, to create an arresting centrepiece,” the retailer said.

The stairs allow customers access between the lower and second floors. 

Athron said: As a brand centred on experience, our teams are constantly looking for ways to ensure that every visit to Fortnum’s is a joyful one. Following record numbers of customers visiting our Piccadilly flagship last year, we made the decision to redevelop the very core of our building to allow customers to navigate our store more easily.

“The result of this endeavour has far exceeded our expectations. The double helix staircase is more than a feat of engineering; it is a work of art, a restoration of architectural integrity, and a symbol of our faith in Fortnum’s future.

“This is the first time in over two decades we have undertaken a project of this scale and ambition at Piccadilly and we are immensely proud of the result. The combination of centuries-old craft and cutting-edge design has produced something truly extraordinary. 

“It will not only transform the way our customers experience the store today, but will ensure Fortnum’s remains one of the most remarkable retail stores to visit in the world, future-proofing our brand for the next 300 years.”

The staircase was designed by the design company Ben Pentreath Studio.
