4 rooms apartment of 625m² in London

Occupying more than 6,700 t across three expansive floors, this extraordinary triplex apartment sits within Walton House, a discreet Knightsbridge address known for its period façade and beautifully reimagined interiors by Mdesign London. A private entrance on the ground floor opens into a generous lobby, complete with its own six-person lift that runs through the entire apartment. From here, a wide staircase leads up to the first floor where the main entertaining spaces unfold. The reception and dining room spans the front of the building and rises over 13 feet high, creating a dramatic sense of space and light. Tall sash windows, intricate detailing and soft finishes make this the natural heart of the home. The adjoining kitchen is practical yet beautifully finished, with bespoke joinery, integrated appliances and a generous island for informal dining. A powder room completes this floor. Upstairs, the bedroom suites are arranged across the second and third floors. Each room has been designed with comfort and privacy in mind, with well-planned storage and ensuite bathrooms. The principal suite occupies the top floor and comes complete with a dressing area, large bathroom and direct access to a roof terrace with sweeping views across the rooftops of Knightsbridge. Below, the leisure level transforms the apartment into a true private residence. A 43-foot swimming pool sits alongside a jacuzzi, bar and lounge area, perfect for entertaining, while a dedicated cinema room offers a more intimate setting to unwind. Walton House itself is one of Knightsbridge’s most discreet addresses, lying between Walton Street’s cafés and designer boutiques, and only a short walk from Harrods and Hyde Park. It’s a location that manages to feel both central and residential, a quiet corner of one of London’s most coveted postcodes.
