Eco-conscious Britons are increasingly turning to an unlikely building material for their new homes: bales of straw. Straw can be cheaper, more thermally efficient and more environmentally friendly than brick, and house builders are increasingly using bales in an attempt to reduce their carbon footprint. By stacking straw bales on top of each other and plastering them with lime or clay, the buildings are made water resistant.
