"Dublin is a much more cost-competitive destination than it may have been before," said Robert O'Shea, a partner at legal firm Matheson Ormsby Prentice who advises U.S. companies on moving to Ireland. "That is reflected in the pipeline of projects we would see for 2012 and 2013."
Facebook is seeking to more than double the size of its European headquarters in Dublin ahead of its $5 billion initial public offering and is considering leasing the former Bank of Ireland headquarters building. More than 350 people work at its Dublin office, set up in 2008, according to O'Leary at the IDA.
Most of the social-networking companies have leased space near the city's south docklands. That's so they can recruit one another's staff, said John Moran, managing director at Jones Lang's Irish division. Endorsement from peers "is always enormously important," which is why companies tend to cluster in a location, he said.
Moran is seeking a 165,000 square-foot headquarters building for Bank of New York Mellon in Dublin. "To find a building in the location that we want, which is primarily south docklands, it will have to be built for us because there's no pre-existing building of a size that actually suits our requirement," he said in an interview.
Financial-services and information-technology companies are expressing an interest in expanding, said Paddy Conlon, a CBRE director who advises multinationals seeking to set up or enlarge operations in Ireland. "A number of pharmaceutical companies are also looking to expand into Ireland" and others are considering moving their headquarters there, he said.
The IDA is already looking for the next wave of companies that will open in Ireland, O'Leary said. The organization keeps a list of companies run by former Google employees it encounters to identify future expansion candidates. The rapid growth of companies like Facebook, Zynga Inc. and Twitter Inc. led the IDA to set up a new unit in 2010 targeting companies with less than $30 million a year in revenue. Thirty five of them have since set up in Ireland, he said.
"We've already got the top 10 companies born of the Internet," said O'Leary. "We ain't gonna stop at that."
