Up-and-coming Dublin practice Heneghan Peng has pulled off another major international coup by snatching the competition to design the new Giant's Causeway visitor centre. Two years ago the firm stunned the architectural world when it won the Grand Museum of Egypt contest (AJ 12.06.03) - and now the practice has done it again by seeing off more than 200 entries from a raft of big-name architects. The competition, which was launched in April this year by Northern Ireland's Department of Enterprise, Trade and Investment, has been one of the most popular in history, attracting an astonishing 800 expressions of interest. It has also been blotted by one of the biggest blunders in competition history (AJ 21.07.05). Although the contest was supposed to be anonymous, a careless official accidentally emailed every entrant with a list of all the other competitors. Run according to UIA rules, second place was awarded to Finnish architect Riina Palva while Portuguese practice Matos Gameiro + Carlos Crespo Arquitectos came in third.
