10 Upper Grosvenor St, London W1K 2NA, UK

Set within a stucco-fronted Georgian building on Upper Grosvenor Street, this four-bedroom duplex is one of Mayfair's most striking entertaining spaces — a rare combination of period grandeur and considered modern engineering, sympathetically refurbished throughout.

The ground floor is defined by soaring four-metre ceilings, a scale seldom found even in Mayfair's grandest townhouses. A double reception room with a working gas fireplace opens onto a fully fitted kitchen and connecting dining room, creating a single, generous entertaining sequence. A study and guest cloakroom complete the floor.

A grand staircase leads to the lower ground floor, where the principal bedroom opens directly onto the main private patio and includes a large walk-in wardrobe and a fully appointed ensuite suite. Three further bedrooms — two ensuite — and a family bathroom sit alongside a second, smaller patio and a separate utility and laundry room.

The apartment is fitted with a lift, integrated security and sound system, and air conditioning throughout — the infrastructure of a genuinely turnkey Mayfair home.

Perfectly positioned on Upper Grosvenor Street, the apartment sits directly beside the Embassy of Monaco and moments from The Chancery Rosewood, within immediate reach of Mayfair's finest boutiques, restaurants and private members' clubs, as well as the open green spaces of Grosvenor Square and Mount Street Gardens. With Bond Street Underground Station (Central, Jubilee and Elizabeth lines) nearby, this is an outstanding London residence or pied-a -terre in one of the capital's most sought-after enclaves.

A residence of this scale and specification rarely comes to market — suited equally as a principal London home or an exceptional pied-a -terre.
