The BBC Television Centre building in Wood Lane has been given grade II listed status.
As the first purpose-built TV centre in the country, its central ring and the famous Studio 1 are of great architectural and historical significance.
The announcement was made by Ben Bradshaw, Secretary of State for Culture, Media and Sport, on July 9, following a campaign led by English Heritage.
Hammersmith and Fulham Council, has welcomed the news, as it feared the history of the BBC would be lost when staff move out in 2012.
The listed areas have features from the 1950s as well as a mosaic from prolific artist John Piper.
There is also a gilded sculpture of the Greek sun god Helios and the well-known studded wall, with its circular discs.
Councillor Mark Loveday said: “The BBC has been part of this borough’s heritage for well over 50 years, even before Television Centre was built.
"We are thrilled that these important cultural buildings, which are architecturally and historically significant will now be preserved for future generations to see.”
The announcement means that any major demolition work or plans to alter existing brickwork, doors, windows or the interior of the 48-year-old building, also need approval from the council.
Television Centre is already on the local register of buildings of merit and stands in the Wood Lane Conservation Area, designated by the council in March 1991.
Caroline Thomson, the BBC's chief operating officer, said: “We welcome DCMS’s announcement of their decision on the listing and their recognition of the historic and architectural merit of these parts of the Television Centre complex.”
