Building work has been completed on BBC Cymru Wales' new broadcast centre, with the developers handing director general Tony Hall the keys today.
More than 80 production companies will have open access to the building, and the Welsh language broadcaster S4C will also have a base at the new centre.
The Central Square building is the first broadcast centre in the world to have a Live IP core. The Corporation is working with Grass Valley and Cisco to introduce IP technology across the facilities. The fit-out of the building is expected to take 18 months.
BBC television, radio and online teams are expected to move to Central Square from the current centre in Llandaff in autumn 2019.
Director of BBC Wales, Rhodri Talfan Davies, said: “The media landscape is changing at a speed never seen before - and Central Square is a crucial part of our strategy to modernise and renew BBC Wales, and to ensure we serve all our audiences across Wales.”
