One Marylebone stands proudly on its own island in the heart of London, offering a rare blend of architectural splendour, contemporary versatility, and unmistakable character. Originally built in the 1820s and designed by Sir John Soane, this Grade I-listed landmark has been thoughtfully transformed into one of the city’s most sought-after event venues. Today, it represents the perfect balance of historic grandeur and modern capability.
From the moment guests arrive, One Marylebone makes an impression. Its striking façade, soaring columns, and timeless proportions set the tone for an event that feels both prestigious and welcoming. Step inside, and the venue opens into a collection of distinct spaces designed to evolve with your vision. The iconic Soane Hall, with its dramatic height, original architectural detailing, and luminous stained-glass windows, offers a show-stopping backdrop for gala dinners, awards ceremonies, large celebrations, product launches, and weddings. The sense of scale is extraordinary, yet the hall retains an atmosphere of warmth and intimacy that makes every event feel personal.
On the first floor, The Galleries provide a bright, elegant contrast – flooded with natural light and offering two elegant wings ideal for receptions, exhibitions, breakout sessions, or more intimate dining experiences. With their neutral palette, these spaces adapt beautifully to both minimal styling and full production builds. The venue’s charm continues across additional spaces, including the landscaped garden to the west and the atmospheric Vaults and mezzanine below, which provide a stylish club-like setting perfect for late-night entertainment and after-parties.
One of the venue’s defining strengths is its remarkable flexibility. One Marylebone remains one of the few central London venues able to comfortably accommodate a seated dinner for up to 320 guests or a standing reception for up to 1,200 across all spaces, while still allowing the event to transition into an after-party environment – all under one roof. Whether you are planning a corporate conference, a glamorous awards evening, a high-profile launch, a fashion show, an exhibition, or a once-in-a-lifetime wedding celebration, every element can unfold seamlessly between the building’s beautifully curated spaces.
This commitment to excellence was recently recognised at the London Venue Catering Awards 2025, where One Marylebone proudly won ‘Best Venue for Gala Dinners, Awards or Weddings’ – a testament to its exceptional service, world-class partners, and its ongoing position as a leader within London’s event landscape.
More than simply a venue, One Marylebone is a place where imagination comes alive and every event becomes a true experience. With its iconic architecture, adaptable spaces, and award-winning credentials, it continues to be a standout choice for clients seeking a London venue that is both historic and unmistakably contemporary.
