The DAA wants to build a €4 billion development over 350 acres to the east of the airport comprising mainly office space.

It says this would become an economic hub targeting foreign direct investment.

Infrastructure would be put in place to enable executives based at the Dublin Airport City to get from their desks to airport check-in an average of six minutes.

They say it would mean 600,000 square feet of office space, along with retail and hotel facilities and an aviation college.

Although it could take 20 years to build.
