Introduction Eco-communities are about building and living overlapping lives. At the centre of many eco-communities is the quest to share – resources, objects, spaces, skills, and care. In eco-communities like Findhorn, Scotland (Figure 1.1), eco-homes cluster together, front doors face each other, pathways are shared, and gardens overlap. The houses seem to spill out into each other with bikes, children’s toys, and plant pots filling the spaces between them.
