Work has begun on a unique £2.5 million building designed to promote sustainable construction.
Genesis, based at Somerset College in Taunton, is being built using sustainable and recycled materials, which will also help to make it energy efficient.
Channel 4 Grand Designs presenter and patron of the project Kevin McCloud, said: "Genesis will serve the western region, and indeed the whole country, as an educational resource centre for sustainable building technologies, both modern and traditional."
The Earth pavilion is currently being built using cob and rammed earth, which was once the primary building material for British structures. It uses the subsoil that in most building projects would be sent to landfill.
While the Timber pavilion will be insulated using recycled newspaper.
It is expected that the buildings will be completed this Autumn for official opening in early 2006.
