Venue History​

The magnificent building One Marylebone was the creation of Sir John Soane – it was built on its own ‘island’ situated in the heart of the City. The impressive venue became a hireable space in 2008 – soon after this opening, One Marylebone became one of London’s leading unique venues.

One Marylebone is a Neo-Classical building which demonstrates the brilliant architect Soane, whose best-known work has been the Bank of England.

One Marylebone was decorated in the mid twentieth century and opened in 2007 as an events venue.
