The Space
The Conversation Room is a vibrant and contemporary event space, ideal for small conferences, meetings, away days, board meetings and training sessions. 

Originally a reading room for Royal Institution members, the Conversation Room is a spacious event venue offering a contemporary twist on our period Mayfair aesthetic. 

The Conversation Room mixes period fireplaces, floor to ceiling bookcases, and expansive windows with modern décor and high- quality integrated audio-visual (AV) equipment.   

Ideal for smaller conferences, the Conversation Room can seat up to 100 people in theatre style and up to 50 in cabaret. 

The Conversation Room can be hired with the adjoining Mezzanine, an ultra-modern indoor terrace space ideal for lunch breaks and post-conference drinks.
