Qatari Diar outlines plan to double the size of Grosvenor Square’s US Embassy building

Qatari Diar has even bigger plans for the US Embassy building on Grosvenor Square than we originally thought… A screening letter to Westminster’s planners tells of an idea to almost double the total floorspace of the building when the Americans move out to Nine Elms, from its current c.260,000 square feet to nearly 500,000 square feet.

The developer / sovereign wealth fund revealed plans to turn the Grade II listed 1960’s embassy building into a 137-room David Chipperfield-designed five-star hotel in April, and has now put forward some tantalising extra details about those proposals.

Additional space will be created by adding two new basement floors and an additional mezzanine basement floor, as well as building an extension at the rear of the building at second to fifth floor levels.

“It is proposed to retain, alter and re-use the existing building to provide a world-class hotel, whilst retaining, repairing and enhancing the principal physical elements of the building’s significance,” said planning advisors Gerald Eve in a letter to planners last week.
