Increase room capacity
The first phase of expansion at the site will increase its hotel room capacity from 72 to 136 rooms and include a restaurant extension that will seat up to 300 delegates.
Wellcome Trust Conference Centre comprises a purpose-built conference centre and a Grade II* listed country house, Hinxton Hall.
Building work on the restaurant extension will begin in October, with both aspects of the project expected to be completed in November 2013.
Rachel Cordier, conference centre manager, Wellcome Conference Centres, said: "This substantial investment in our product and ongoing plans will give us a stronger market presence and help us approach new customers and market sectors. An increased room inventory, as well as a larger and improved restaurant, will also allow us to pitch for larger pieces of business which will in turn have a positive impact in Cambridgeshire's economy."
The Cambridge centre – which has nine meeting rooms, including an auditorium for 300 delegates – is the sister venue to the Wellcome Collection conference centre in London.
