Sarah Jane Adventures, Casualty, Upstairs Downstairs, and Pobol y Cwm. Located in Porth Teigr, Cardiff Bay, Roath Lock Studios gained permission in January 2009 and construction began in June 2010 with the building topping out in February 2011. Production began at the site in autumn 2011 and the site was officially opened on 12 March 2012. As a result, Pobol y Cwm moved from the Llandaff studios and Doctor Who moved from Upper Boat studios to the new complex, with Casualty joining them at the site. Despite being designed to house them, the site never housed the Sarah Jane Adventures, following the death of main actress Elisabeth Sladen in 2011, or Upstairs Downstairs, following the series' cancellation. BBC National Orchestra of Wales operated from a purpose-built orchestra studio, Studio 1, in Broadcasting House from 1966 to 2008. They then moved to new purpose built facilities at BBC Hoddinott Hall in January 2009, as part of the Wales Millennium Centre campus. Broadcasting House, Llandaff Until 2020, BBC Cymru Wales's headquarters were at Broadcasting House, Llandaff, Cardiff. The studio centre was built in 1966 and opened the following year as a purpose-built location to house the expanding presence of the BBC in Cardiff. The centre contained studios for the news programmes, radio space including that used by the BBC National Orchestra of Wales until 2009, and another studio for drama productions constructed in the mid-1970s. It was the first time that all of BBC Cymru Wales's departments within Cardiff were located on one site. Broadcasting House was built next to Baynton House which housed all of the BBC Wales' operations from 1952 until construction was finished. Baynton House remained in use by the BBC until 1975 when it was demolished to make way for the E-Block extension. Previously, the BBC in Wales had been located in the converted Broadway Methodist Chapel on Broadway in Roath, Cardiff from 1955, and in nearby premises on Stacey Road in Roath, Cardiff from 1959. A temporary broadcasting centre was set up on the banks of the River Taff, in 1958 to cover the Empire Games. While these studios played host to drama, entertainment and regional programmes, the site was still not ideal. The site only held two studios, both located in the church, and the ability to broadcast film was not installed on the site for several years; film played into programmes from a telecine machine
