Following the opening of the High Speed 1 to the station, redevelopment of the land between the two major stations and the old King's Cross railway lands to the rear commenced. In 2008, Argent, London & Continental Railways and DHL formed a joint partnership: Kings Cross Central Limited Partnership. Outline planning permission, prepared by Allies and Morrison and Porphyrios Associates, was granted for the whole site in 2006. Detailed planning applications for each part of the site are being made on a rolling programme basis.
