Dun Laoghaire's ferry terminal is to be converted into a business hub for technology, marine, and design firms.
The 'Harbour Innovation Campus', as it will be known, will be able to accommodate up to 1,000 members across the terminal's former arrivals hall, departure lounge, baggage hall, and ticket office buildings.
The innovation campus also plans to provide a world-class maker space on-site for creative prototype design in wood, metal, plastic and electronics.
The campus is expected to be open for business from the middle of next year.
The change of purpose for the ferry terminal follows the move by Stena Line in 2015 to discontinue its Dun Laoghaire-Holyhead route with the Stena HSS.
This marked the end of Dun Laoghaire-Holyhead services after 204 years.
It is believed the project will inject in the region of €20m into the building and local economy over the next ten years.
