One Marylebone

Built in 1826 on its own ‘island’ in the heart of the capital, One Marylebone has rapidly become a firm favorite for event organisers and private clients looking for an elegant, yet flexible venue. Beautifully refurbished to the original designs of Sir John Soane, the Grade I listed venue boasts 3 unique spaces plus landscaped garden, moments from Regents Park. The grandeur of One Marylebone has attracted blue-chip brands from a variety of industries with a focus on fashion, beauty and the arts. One Marylebone is a glamorous and unique central London venue, used for the most exclusive private and corporate events. The building was deconsecrated in the middle of the twentieth century and returned to its former glory in 2007 when it opened its doors as London’s most exciting new event's venue.
