has climbed one of the cranes building the skyscraper in to meet its operator, who said he “never tired of the view”.

When finished the Shard will tower 1,016ft (309.67m) above London. As floors are constructed, the crane also has to keep growing taller than the building for work to continue.

Operator John said he often worked “blind”, as he could not see the steel he was moving hundreds of feet below.

Andrew Marr's Megacities looks at how people live in five of the world's biggest cities – London, Dhaka, Tokyo, City and Shanghai. The first programme Living in the City can be seen on One at 2000 BST on Thursday 2 2011 and afterwards on BBC iPlayer.
