Standing proudly on its own island in the heart of London, One Marylebone is a venue unlike any other. Originally built in 1826 and designed by the celebrated architect Sir John Soane, the former Holy Trinity Church is steeped in heritage, a legacy that continues to define its distinctive character today…
Since its transformation into an event venue in 2008, One Marylebone has become one of Londonโs most iconic and versatile spaces, seamlessly blending historic grandeur with contemporary sophistication.
From its inception, One Marylebone has been designed to inspire. Whether hosting an elegant garden reception for up to 250 guests or a full-scale indoor celebration that maintains both atmosphere and intimacy, the venue adapts effortlessly to a wide range of occasions. It remains one of the few London locations capable of accommodating a seated dinner for up to 320 guests or a standing reception for 500, all without compromising on impact. Enhancing its versatility further is the unique opportunity to continue the evening with a private, club style after party, all under one roof.
The venueโs collection of flexible spaces allows for exceptional creativity and seamless flow. From awards ceremonies, conferences and gala dinners to exhibitions, film premieres, fashion shows and weddings, One Marylebone has hosted an array of high-profile brands, corporate gatherings and private celebrations. More than simply a venue, it is a setting where imagination is encouraged and ideas are brought to life, elevated by timeless surroundings and considered design.
You are invited to an exclusive open house showcase to experience One Marylebone
To showcase the breadth and character of the venue, One Marylebone will host an exclusive Open House showcase evening on Tuesday, 3rd March for event professionals. This immersive experience will include a dedicated walkaround of four distinctive spaces: The Soane Hall, The Galleries, The Vaults and The Garden. Each space will be styled to highlight its individual character, versatility and potential, allowing guests to envision how a wide range of events can be seamlessly delivered within the venue.
Throughout the evening, guests will enjoy refined seasonal bites curated by the in-house catering team, One Dining. Renowned for its considered menus and elegant presentation, One Dining will present its approach to contemporary hospitality, offering flavours designed to enhance the overall experience.
In celebration of the arrival of spring, the Open House will also feature a bespoke flower pressing experience in collaboration with florist partner Flower and Press. Inspired by the beauty, colour and renewal of the season, this interactive element invites guests to explore their creativity and create a pressed floral keepsake to take home, serving as a tactile reminder of an evening designed to inspire.
