London Design Week has kicked off with a few choice shows and events including Michael Cross' Bridge installation at Southwark Park where the public is welcome to attend and walk on water. Bridge is a spectacular new site-specific design commission for Dilston Grove by Michael Cross. Housed in a former church, (one of the earliest examples of poured concrete construction and a Grade II listed building), the piece comprises submerging two thirds of the inside of the church in water, and producing a series of steps which rise out of the apparently empty man-made 'lake' as you walk across them. Each step emerges one step in front of you and disappears back underneath behind you as you go. This 'bridge' is purely mechanical, the weight of the person on it depresses each step a little, this force activates a submerged mechanism which raises the next step.
