That's the digital studio at Grays Inn Road that ITV News use for their online programmes (such as the Royal Rota with Chris Ship, Now What? with Robert Peston, and Young, British and Muslim with Rageh Omar). Looks to be tucked away in the corner of the newsroom (presumably not where the old newsroom sets were!).
I think its the same studio that they used to use for YouTube daily news roundups a while ago.
