 An unusual feature of the studio is a soundproof double door which can be lowered in 30 minutes to reconfigure the space into two separate studios, each with its own independent control facilities.When used as a single studio, it was the largest fully equipped television studio in the UK – 500 sq ft larger than HQ1 at Dock10, MediaCityUK in Salford and 2,000 sq ft larger than Studio 1 at BBC Television Centre.Internationally, larger studios exist in Germany and in the United States, although many of these fall into the category of soundstages and are not fully equipped television studios.
