24 Grosvenor Square

US Embassy Exterior, 1960-2018 (click to enlarge). Image by Bill Boaden.The United States Embassy, London, was first established in 1785 and has been located in several locations during its history. On September 24, 1960, it officially moved to a chancery building located at 24 Grosvenor Square, Mayfair, London.

Designed by Finnish-American architect Eero Saarinen, the structure had over 600 rooms on nine floors, providing 225,000 square feet of working space for about 750 employees, less than half of whom were American. Only five or six of the floors, including a โ€œpenthouseโ€ set back from the facade, were above ground level to conform in height with the surrounding buildings in Grosvenor Square. The remaining floors were below ground.

In the late 1980s, the embassy was served by the Bond Street station, located about a five- to seven-minute walk away.

For security reasons, specific interior room numbers and exact floor assignments are not published in public architectural or historical building records. In the Restless Hearts series, I have placed the main operations of the Regional Security Office on the fourth floor (UK: third storey). I have placed the visa application offices on the first floor (UK: ground floor), with most administrative operations occurring on the first and second basement levels. The Ambassador’s ceremonial office is also on the first floor/ground floor, but the Ambassador’s working office is one floor up.

Initially, due to limited room, his office was a converted janitorial closet on the fourth floor of the building, down the hallway from the RSO’s office. Although the office was private and secure, its original use was always evident in its design.

This level also contained her supervisor’s office, a loading dock, and a small research room. While the area was kept in good condition, it was never as luxurious as the office areas above ground โ€” and it was never meant to be.

The Embassy officially opened its new location at 33 Nine Elms Lane on January 16, 2018. The former location, which now has the address of 30 Grosvenor Square, is the Chancery Rosewood, a luxury hotel.
