One Carrington Place — Mayfair Penthouse

Occupying the sixth and seventh floors of a discreet Portland-stone landmark moments from Berkeley Square, the penthouse at One Carrington Place is among the largest lateral residences to be offered in Mayfair in recent years. Nearly 9,000 square feet of accommodation is arranged around a sculptural bronze staircase, with principal rooms enjoying a rare double aspect over Green Park and the rooftops of St James's.

Interiors by Marlow & Hale pair English restraint with continental warmth: book-matched walnut, antique brass, hand-troweled plaster, and five fireplaces. The upper floor is given entirely to the owner's quarters — bedroom, twin dressing rooms, marble bath, and a study opening to the south-facing roof garden with outdoor kitchen and dining pergola.

The building offers the full Mayfair service canon: 24-hour concierge and security, valet parking for three cars, a private wine cave, and direct lift access into the apartment's entrance gallery. Offered with a 999-year lease; price and further particulars on application through Harcourt & Vane.
