Office originally designed by Foster + Partners
Mace's upgrade of the central London office occupied by broadcasters Channel 4 and ITN has been finished.
The building at 200 Gray's Inn Road was originally designed by Foster + Partners and opened in 1991.
It is currently occupied by a number of other high-profile media organisations, including Warner Bros.
The wider project team included shell and core architect Ian McArdle and fit-out architect Conran and Partners.
Building owner Great Portland Estates said it wanted to change the ground floor layout to meet modern workplace needs. This now includes a cafe and informal workspace.
Channel 4 is due to open a new national headquarters in Leeds and has hired Sir Robert McAlpine to turn the grade II-listed Majestic building in the city centre into its new home.
