Network Rail has confirmed the timetable for the competition to redesign the front of King's Cross station has been derailed.
It was originally hoped that a winner of the contest to create a new urban square in front of the famous station would be unveiled in December.
However, a shortlist in the two-stage competition, which was launched back in June, is not expected to be released until next month – with a final announcement about the victor delayed until early 2009.
Network Rail blamed the popularity of the contest, which attracted 101 expressions of interest for the hold-ups.
A spokesman from Malcolm Reading Associates, which has organised the competition, said: 'The process for assessing the expressions of interest has taken longer than anticipated – a consequence of the exceptional quality and number of entries and the holiday period in August. We are almost at the end of this process and Network Rail anticipates announcing the shortlist by early November.'
He added: 'This is a change to the competition timetable but not to overall delivery by 2013. We will provide a revised timetable to those shortlisted... we are grateful to all competitors for their patience.'
