One Marylebone (also include links to the Virtual tours)


The Soane Hall is the jewel in the crown of One Marylebone. At over 27 feet high, the room is impressive in size as well as beauty. The seated capacity is 350 people. The space is very flexible to a client’s bespoke ideas.


The Galleries are located on the First Floor of One Marylebone and are the most contemporary and bright of the building’s spaces. Taking the form of a ‘U’ shape, the space is split into East, West and South Galleries. The former two are flooded with natural daylight from floor to ceiling windows and these spaces epitomize the heart of the architect’s passion for light and its effect on a room.

The Galleries can be hired as one space or used as an incredible contrasting reception space for a main function in the Soane Hall.


One Marylebone has two external areas, running parallel to both the West and East sides of the building.

The West Garden is the perfect addition to any event needing external space. Whether a reception or an evening drinks party or simply an area for those guests wanting some fresh air, but still involved with the event.
