The Mansion's glazed terracotta façade references the predominantly Edwardian aesthetic of the area and features a subtle variation in colour and tone. The façade's thé-au-lait' - or tea with milk - tone was developed with a specialist company in Germany, and is inspired by the tiles on the nearby Wigmore Hall.

Beginning with the dramatic five-metre wide, double height entrance and running throughout the building, the flow of the spaces at The Mansion has been carefully considered so the route to each apartment is calm and uplifting, and feels like a welcoming retreat and respite from the busy streets of Marylebone.

The apartment itself is centred around a large open plan living space with a feature fireplace. The principal bedroom features a spacious walk-in wardrobe and luxurious en-suite bathroom. Full height windows frame the changing seasons and an interior palette of contemporary and traditional materials creates an elegant and understated aesthetic with warmth and character.

Just a few steps from Mayfair, it offers access to everything the celebrated district has to offer. At the same time, its setting within Marylebone provides the rare opportunity to appreciate the quieter, more relaxed surroundings of central London's last remaining village.

The Mansion has been designed to offer its residents the finest amenities. On arrival, residents are greeted by a dramatic travertine-lined double height lobby with 24/7 Concierge. A curved staircase sweeps down from the lobby level to reveal the 25m private pool, the largest in Marylebone, as well as a state-of-the-art fitness studio, private treatment room, sauna and steam room.
