About Us

One Great Spectacle

Headquarters of the Institution of Civil Engineers (ICE), this historic Grade II listed building was constructed between 1910 and 1913.  

The conference, event and wedding venue is located in the centre of Westminster and has 21 function rooms including the stunning Great Hall which can host events for up to 400 people.

There are two lecture theatres with tiered seating and capacities of 106 and 240; both are fully equipped with a full range of audio visual technology. We work in partnership with Eclipse Presentations who have a team of three experts permanently on site and on hand to assist with all your audio visual requirements.

Since it was established as an independent venue in 1987 One Great George Street and the team who run it have built a well-earned reputation for providing flawless service in impeccable surroundings. The venue has a renowned in-house executive chef, kitchen and catering team.

Sustainability and accessibility are important to us and we are always looking at ways at improving and enhancing our venue to make sure we continue to meet the highest standards.
