I never thought that this day would come for me,” Stella McCartneytells Vogue while reclining on a pink Mario Bellini sofa on the first floor of her shiny new global flagship on Old Bond Street. “I think it’s quite rare to have a woman designer with her name on the door, and I’ve really gone the extra mile to tell the story of who we are at the house of Stella McCartney.”

Number 23 might be a grade II listed 18th-century building, but inside it’s a modern multi-sensory experience that explores the brand’s philosophy to reclaim, re-use and recycle. “Stella Rocks”, an indoor rockery comprised of rocks sourced from the McCartney farm in Campbeltown and replanted moss and thyme, greets guests on the ground floor; office waste paper has been transformed into decorative papier-mâché panels on the first floor; pink fur-free fur material from previous collections lines the walls of the “Stellavator”; and the prized vintage furniture she has acquired over the years is given homes next to reclaimed timber plinths, silicone installations and foam speakers. It’s a textural feast, and that’s not even taking into account the ball pool and climbing wall (all white, very chic) in the children’s department.
