Description: Inspired by the flight pattern of a spinning bat, the Bat Spiral is a dynamic, floating spiral of beams that accommodates roosts for the 17 British species. Raised on a cluster of thin bars, which resemble a bed of reeds the Twenty-four roost types are positioned within the biocomposite spiral as if they were the spokes of a wheel to maximise heat gain from the sun except for the Greater Horse Shoe Bats summer roost, that are insulated and kept at a constant temperature by earth pipes. Specially designed incubators keep this species winter roost a constant temperature. |
