In May 2005 the BBC's relationship with Land Securities Trillium was significantly restructured to focus on completing two other property developments currently in progress at Pacific Quay in Glasgow and Broadcasting House in Central London. All other services are terminated, by mutual consent, with effect from 31 March 2006, with an option to extend by up to six months at the BBC's discretion. It is estimated that the partnership arrangement has saved the BBC £33 million in today's money, across the 49 locations covered by the partnership, between its inception in November 2001 and termination in March 2006. This saving is as compared to the cost projected by the BBC's "own delivery" comparator.
