In short: Walpole Mayfair is a boutique residential building at 4–5 Arlington Street in St James's, just off Piccadilly and close to Green Park. Redeveloped in 2012 by Oliver Burns, it contains just five apartments, including a penthouse with a large terrace that set a high price per square foot when it sold. Arlington Street is historically linked to Sir Robert Walpole, Britain's first prime minister, who lived on the street, which inspired the building's name.
