This new complex by W-One International lies right at the heart of Marylebone, with a discreet entrance on Beaumont Mews just steps from the neighborhood’s boutiques, cafes and art galleries. The development has five four-bedroom townhouses, 13 apartments and three penthouses, all housed in a former 1930s Art Deco-style building that was once BBC Radio’s headquarters. Double-height oak doors welcome you into each townhouse, where steps lead from the grand lobby down to the ground floor with an open-plan kitchen, dining room and lounge with fireplace. An inner glass atrium extends all the way up to the building’s retractable glass roof. Sliding doors enable you to create a fully open-plan space on each floor. Stairs lead up to the reception room and master bedroom on the second floor, and the third floor’s three bedrooms, utility room and bathroom are connected by a skybridge. The architectural design of Dixon Jones and interior architecture of Darling Associates is complemented by Sophie Paterson Interiors. The firm combined silk wall coverings and bespoke joinery with light, earthy and tactile finishes.
