About this home

This landmark property in the historic West Wing of One Grosvenor Square, this 5,300 sq ft home pairs grand lateral space with an atmosphere of total privacy. Recently refurbished to an exceptional standard, every room has been designed with a level of detail more often associated with a private members’ club than a home. The result is one of the square’s most incredible interiors, combining classical proportions with a modern palette of marble, bronze and bespoke cabinetry throughout.

The apartment unfolds across the ground and lower ground floors, connected by a sweeping internal staircase and served by a private lift. The ground floor begins with an impressive entrance hall that sets the tone for the scale to come. From here, a vast reception room stretches across the width of the building, arranged for both formal entertaining and quieter evenings at home. High ceilings, tall windows and immaculate joinery define the space, complemented by a dining area framed by richly dressed wall panels.

The principal suite sits quietly on this level, arranged as a private wing overlooking the square. It includes a generous bedroom, a large dressing room with extensive wardrobes, and a bathroom finished in marble with twin basins, a walk-in shower and a deep bathtub.

To the rear, the kitchen has been designed for both daily use and catered events, with Gaggenau appliances, a long central island and textured stone worktops. A family room sits alongside it, offering a more relaxed setting with bespoke media cabinetry and views into a sheltered patio.

The lower ground floor holds the remaining bedrooms, three with their own bathroom and each with a distinct design identity. The standout suite has a dressing room, presented in a lighter palette to the principal and access to the terrace that wrapsaround this whole level. All bathrooms feature detailed stonework, soft lighting and brass or nickel fittings. A gym, treatment room and extensive storage vaults complete this level, along with direct lift access back to the upper floor.

A private terrace runs along the rear of the building, creating a rare outdoor retreat in the heart of Mayfair with space for dining and planting. Residents of One Grosvenor Square benefit from 24-hour concierge, secure parking and access to world-class amenities.

Grosvenor Square remains one of London’s most prestigious addresses, moments from Mount Street and the boutiques of the Grosvenor Estate. The area is entering a new chapter, shaped by the transformation of the former US Embassy into the Rosewood hotel. The combination of heritage architecture, exceptional privacy and a growing collection of destination restaurants continues to make this one of London’s most admired locations.
