This month, we talk to Bryan Berg on his first visit to London for his most recent project. He currently holds the record for the largest playing card structure (10.39 m (34 ft 1.05 in) long, 2.88 m (9 ft 5.39 in) tall and 3.54 m [11 ft 7.37 in] wide), and the tallest house of cards (7.86 m [25 feet 9 7/16 inches]). Since 1992 he has broken his own records 8 times.
