Company 4th Birthday Party

Venue: One Marylebone

To celebrate their fourth year, Make Up Revolution took over One Marylebone and invited 500 guests to party the night away. The venue looked incredible and was produced by Bespoke Events London with food and drink provided by One Dining.

“The event at One Marylebone went down without a hitch – the team onsite were a dream to work with – accommodating, friendly and very professional at all times. I would not hesitate to recommend your venues to our clients in the future.”

Electric Sky Launch Party  

Venue: One Belgravia

In line with their UK activation Electric Sky held a huge press party at One Belgravia. A collaboration between Universal Music owned Interscope Records and Origin Wine, the idea is to make drinking wine at events and concerts easier when in big crowds.

The venue was lit in brand colours and DJ Jax Jones was there with his huge hit “You Don’t know me” blasting out to the 300 strong crowd! One Dining served up, among other things, their celebrated mini beef wellingtons and monk fish tacos!.

One Marylebone

Soane Hall

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.

The Courtyard (Gardens)

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. This space would be perfect for an outdoor reception, an evening drinks party or simply an area for those guests wanting some fresh air, but still involved with the event.
