Objectors to a €350m overhaul of RTE's Montrose studios are expected to air their grievances at a planning hearing this afternoon.
The national broadcaster says the redevelopment known as 'Project 2025' is necessary to cater for the digital age.
If it goes ahead, the €350m refit will allow RTE to host all of its services in a new purpose-built complex over 17 acres.
The masterplan is to develop the site over the next 10 to 15 years, constructing new high-definition digital TV studios, radio studios, offices, even a public plaza.
RTE says the existing buildings, most of which are to be demolished, house outdated analogue equipment and could not be re-engineered or adapted for the digital age.
Planning permission was granted last April, but objections from local Donnybrook residents (including financier Dermot Desmond) are due to be aired at an oral planning hearing today.
