There is a signal box like structure on top of our building.
Originally it was used to monitor traffic on the eight commuter rails that run past the building, Waterloo to Vauxhall. We like the idea of the box being used again; for illuminations during the dark winter months and more intimate, organic work in the summer.
Earlier this year we fixed a neon Pleasure sign to the box and this August architect Christian Kerrigan hung a bottle inside it. He filled the bottle with water from the Thames at low tide. Algae is what gives the Thames its muddy appearance and we are now watching the algae in the bottle grow.
Christian is interested in the potential of algae to power buildings. Arup recently unveiled the world's first algae powered building in Hamburg. Our bottle, continuously topped up with rainwater, is a signal of the inventive ways we might power our building (VGCC) in the future.
