The 13,100sqm of events space will be created over a single floor in County Hall and will open in January 2017. The space will consist of 20 different rooms, the largest conference room of which will have the capacity for 400 delegates, while the Thames and Country Suites together will be able to host 900 delegates.
The space, which was last occupied by the Greater London Council in the 1980s, will undergo a multimillion-pound renovation that will see the restoration of original parquet floors and art deco windows. The venue will feature wi-fi and A/V technology throughout, while many of the rooms will offer views over the Thames to The Houses of Parliament and Big Ben.
Margaretha Welsford, director of sales for etc.venues, said: "Etc.venues County Hall is setting out to make a big bold statement to the London venue market. It’s an iconic building in an exceptional location and we believe will be a big hit with a wide range of UK and International event planners seeking a new and different London venue.
"Our clients have been urging us to open something bigger and nearer the West End and after a two-year search we’ve found the space our designers can transform into not just a top London venue, but a world-class venue."
