Unfolding over five floors and 3,979 sq. ft, the property has outstanding entertaining spaces, being one of only two terraced houses in Belgravia with a double-volume drawing room.

Dual aspect, it is exceptionally impressive, with soaring double-height ceilings, making it perfect for hosting.

On the lower ground floor, the more informal eat-in kitchen is paired with a lovely casual sitting room. An ensuite bedroom, which would make wonderful staff accommodation, and a utility room are also on this level. French doors open to a third, verdant patio from the sitting room.
