The Dublin Airport Authority has revealed plans for a €4bn (£3.1bn) business park aimed at becoming Ireland’s ‘new premier location for international business headquarters.’

The Dublin Airport City project will be built over 15-20 years on a 350 acre site to the east of the existing airport.

It will include nearly 6.5m sq ft of offices and 430,000 sq ft of retail, hotel and conference space.

The scheme is expected to provide approximately 30,000 jobs, including up to 2,000 construction and fit-out jobs a year over the construction lifetime of the project.

It will be designed by architect HOK and CB Richard Ellis will provide the DAA with property advice.

Declan Collier, chief executive of the DAA, said: ‘The clustering of travel intensive businesses at Dublin Airport City will sustain the ongoing development of Dublin Airport. Crucially, it will help the airport maintain its status as one of the most competitive airports globally and position Ireland as a key gateway to world economies.

‘The masterplan for Dublin Airport City is aligned with Fingal County Council’s Local Area Plan (2006), which focuses on the growth of Swords as the region’s principal population centre, on addressing the imbalance in the supply of quality office locations in North Dublin and on significant public transport initiatives such as Metro North.’
