The wooden complex on the quayside is an eco-building. As well as a bar there are offices, a nursery and three wind turbines on the roof.
I was sitting by the river enjoying a sunny drink when there was a bang overhead. A seagull and its severed wing plopped into the water in front of me.
A friend who works in one of the offices says that this is quite a common occurrence. When a bird flies into the turbine that overlooks the nursery, the children in the play area below are showered with blood, feathers and bits of seagull.
