One Marylebone

One Marylebone is a landmark London venue in the Marylebone area, where architectural details - from ornate stonework to soaring interior volumes - give events a sense of occasion that few spaces can replicate. With a maximum standing capacity of 750 across Soane Hall and The Galleries combined, it offers genuine scale for large-format gatherings, while Soane Hall alone accommodates up to 450 standing, providing a distinct space when a more contained configuration is needed. Five spaces in total give planners room to consider different layouts and flow. On-site facilities include AV equipment, a sound system, high-speed internet, air conditioning, natural light and breakout rooms - a practical foundation for events that need both atmosphere and reliable infrastructure. Great Portland Street Underground Station is a one-minute walk away, with Regent's Park Underground Station reachable in four minutes on foot. London City Airport is approximately 47 minutes by car. The British Museum and Camden Market are each around eight minutes away by road.
