William Whiteley built his eponymous department store in Bayswater at the turn of the twentieth century, calling himself the Universal Provider and stocking everything from groceries to funeral arrangements. That spirit of total provision now finds an unlikely successor in Six Senses London, which opened in 2026 as part of Foster + Partners' £1.5 billion redevelopment of the Grade II-listed building — a project that preserved the original Edwardian façade, the central dome visible from the guest rooms, and a grand staircase modelled on Milan's La Scala. EPR Architects served as hotel architect and lead designer, with AvroKO shaping the interior concept across 109 rooms and suites on eight floors. The exterior colonnade, dressed with trailing greenery and terracotta pots between paired limestone columns, sets a tone that the interiors carry forward with warmth: herringbone oak floors, Carrara marble bathroom surfaces, sage-green tile splashbacks with unlacquered brass fittings, and freestanding black-steel shower enclosures that read almost as architectural objects in their own right. The all-day restaurant is finished in white marble with black diamond inlays underfoot, cane-backed chairs pulled up to white stone-topped café tables, and slub-wood ceiling panels softening the volume above pendant globe lights. Deepest underground, the 2,300-square-metre spa is the property's most extraordinary space: a pool room enclosed by sweeping biomorphic archways in warm ochre plaster, the forms closer to Gaudí than to anything else in London.
