TRADE union SIPTU has withdrawn a planning application seeking to redevelop its Liberty Hall headquarters, one of the capital's most iconic buildings.
The union said yesterday it had decided to spend extra time getting the design "right", and planned to submit a fresh application within three months.
Plans to demolish Liberty Hall and build a 18-storey building on the site were first mooted in 2006, and planning permission was sought from Dublin City Council in 2009.
The top three stories of the tower would include a heritage centre and viewing platform open to the public.
But the council sought additional information about the design, and yesterday the union decided to withdraw its plans and submit a new application in the summer.
"We have decided to withdraw the current planning application due to detailed design issues," SIPTU General Secretary Joe O'Flynn said.
"While the union, its professional advisers and Dublin City Council officials have worked hard to resolve these outstanding issues, time simply ran out on us.
"After detailed consideration, SIPTU has withdrawn the application to allow more time to resolve these matters and we intend to re-apply for planning permission within three months."
The union remained committed to the project as the current building was no longer "fit for purpose", he added.
