Truly Eco Accommodation

Here at CAT we believe in a world where humans tread lightly on the earth while enjoying a high standard of living. Our 4 star accommodation options support this vision.

Buildings have been carefully designed with consideration to eco methods and materials, energy consumption is carefully minimised and on-site renewable energy installations feed into the grid. Buildings are heated by our on-site biomass boilers, and showers and basins in the WISE building are heated by solar-thermal cells on the roof.
