RTÉ has been given the go ahead from An Bord Pleanála for a €350m redevelopment of its Donnybrook site in Dublin.
Project 2025 will involve housing all of RTÉ's facilities in one purpose-built complex, including five television studios and a public plaza.
Submissions were heard that the redevelopment is necessary to allow RTÉ to adapt to the digital and high-definition age, which cannot be done within existing facilities.
There were objections from the nearby German Embassy, as well as financier Dermot Desmond and other local residents.
It will mean the construction of three blocks of broadcasting facilities covering around half of the campus and rising to a height of nine storeys.
The radio centre and multi-storey carpark will be demolished.
The construction will take place in five stages over 15 years.
An Bord Pleanála has granted a 10-year planning permission to commence work because of the size of the development and the need to maintain broadcasting.
In a statement, RTÉ welcomed the ruling saying it was an important milestone in the organisation meeting its obligations in a digital age.
