The event was attended by outgoing BBC Wales director Menna Richards, one of the driving forces behind the new development, who said:
There’s still a lot more work to do, but once completed, Roath Lock studios will become a focal point for the creative industries in Wales – brimming with energy and talent – and we are all extremely proud to be a part of the project.Other guests included Welsh heritage minister Alun Ffred Jones, Cardiff Council leader Rodney Berman, and Mark Hallett of site developers Igloo Regeneration.
The first shows at the 170,000 sq ft site (Casualty and Pobol y Cwm) are due to commence production in Autumn once the buildings are fitted out. Doctor Who and The Sarah Jane Adventures will re-locate from the Upper Boat Studios in Tonteg during 2012 - a move meaning that Doctor Who's 50th Anniversary will be marked at the brand new facilities!
