Frank Gehry first started working with Facebook last year on the design of its new Silicon Valley campus, but will now work with the company to replace its existing offices in the UK and Irish capitals.
The new London headquarters will reportedly occupy three floors of 10 Brock Street - a British Land development at Regent's Place, London. With an area of 8000 square metres, it will double the size of the existing Covent Garden address and will place Facebook in the same building as rival social network Twitter.
"Our new home will give us the space to double the number of people working at Facebook London and build on what we’ve achieved there over the past few years," Facebook's European chief Nicola Mendelsohn told the Evening Standard.
Facebook's Dublin staff will relocate to a new 11,000 square-metre space in Grand Canal Square, allowing capacity for up to 1000 employees.
Gehry, who is best-known for buildings such as the Guggenheim Museum Bilbao and the Walt Disney Concert Hall, is also designing an office in New York for the company's engineering team. He is still working on the Silicon Valley campus after being asked to "tone down" the original designs.
