Environmental sustainability is the cool kid on the block of home improvement - you may already be familiar with the ethos behind the earthship. Earthships are innovative and environmentally-conscious homes. They’re made of recycled materials and are designed to be relatively self-sufficient, often powered by solar panels and harvesting rainwater. Ideally, they should include features to ensure both heat insulation and natural ventilation. Above all, their construction discourages reliance on mains energy powered by fossil fuels. Yet, what many people don’t realise is that such homes can be cosy and beautiful too. Here’s some proof you can go off-grid and still enjoy a comfortable lifestyle.
