A second fast track planning permission has been granted for Dublin's Docklands.

It means that a combined €450 million office and apartment development on Sir John Rogerson's Quay and Hanover Quay can now go ahead.

Dublin City Council today gave planning permission for the plans for Hanover Quay having given permission for the site on Sir John Rogerson's Quay last month.

Both sites are part of a Strategic Development Zone, which means the planning permission cannot be appealed to An Bord Pleanála.

The total development will involve office space for a total of 2,400 workers and 158 residential apartments, and will be called The Reveal Developments.

The scheme is being promoted by TIO plc, an umbrella group involving US investors Oaktree, the Irish property company Bennett Group and the National Asset Management Agency.

The Sir John Rogerson's Quay side of the site was once owned by Mountbrook, the company established by developer Sean Dunne.

This backs onto the Hanover Quay site on Grand Canal Dock which was once used by Kilsaran Cement.

Justin Bickle, Chairman of TIO plc and managing director of Oaktree welcomed the decision for the 'silicon docks'.

"The purpose of designating the area an SDZ was to facilitate fast track planning applications for much-needed commercial and residential development - this proves that the system is working well in practice", he said.
