It's that time of year again: the London Design Festival. A week of non-stop local and international design, across London. With more than 300 events in spaces ranging from an old postal sorting station to the great outdoors, it's a rush to see the best.

Opening the Festival is the Endless Stair, 15 interlocking staircases made from laminated American tulipwood, sitting in front of the wonderful Tate Modern art museum.
