Large conferences

Our large conferences package includes exclusive use of our spacious Ondaatje Lecture Theatre with a fully integrated system for plenary sessions, bespoke LED lighting to compliment your branding, and a digital desk with various options and capabilities. The nearby Map Room, Main Hall and Education Centre are three flexible and unique spaces to host delegates for networking and catering breaks.

RGS provides a very special venue for events and I have always loved the Ondaatje Theatre in particular. Despite its impressive capacity, it is a surprisingly intimate space enabling the audience to fully engage with the speakers. - Institute of Economic Affairs

Event spaces

Our state-of-the-art Ondaatje Lecture Theatre is fully equipped with award-wining AV systems to deliver impactful conferences. The Theatre stage can be set with a lectern as well as a formal panel table or relaxed armchairs for an interview style. The Theatre has a maximum capacity of 700 seated (422 on the ground floor and 278 on the balcony), so comfortably accommodates 450 delegates for an all-day conference.

The nearby Map Room, Main Hall and Education Centre make a stunning setting for refreshment and networking breaks accommodating up to 450 delegates standing combined (150 per room). Steeped in history, the Map Room and Main Hall are also perfect backdrops to host exhibitors and stands – get in touch with the venue team to discuss your event setup, and we would be pleased to advise how many exhibitors can be accommodated.

For conferences with 300 of fewer delegates, our bright and spacious Education Centre can alternatively be utilised for breakout sessions, either accommodating up to 100 in a lecture theatre style layout or up to 60 in a cabaret style.

If you’re in need of a green room, breakout area or meeting space, our Sunley and Drayson Rooms can be added on to your package. Both on the ground floor, the rooms can accommodate up to 18 in a boardroom style and come equipped with our standard AV. For additional space, the venue also has two further meeting rooms on the first floor.
