The Campaign to Protect Rural England's annual season of guided tours at energy-efficient buildings across Norfolk. From cottages to mills, barns to smallholdings, studios to sheds - each of the 12 buildings opening their doors has something different to offer. Many harness the energy of the wind, sun, river and rain. Some are hand-made - built from straw, cob, earth or timber. Some have roofs of sedum, wildflowers and grasses. Many use sheep's wool, recycled newspaper and other recycled or reclaimed materials. Visit
