Cities are the affirmation of civilisation and human inventiveness. They are at once fragile organisms in constant need of care and battlegrounds of conflicting interests. And above all, they're ours. The smart guide to Utopia showcases 111 projects, initiatives and ideas from all over Europe that make our cities better places. Whether it be an underground waste disposal system in Barcelona or a public swimming pool converted into an arts centre in Berlin, a self-sufficient urban garden or a solar-powered pop-up restaurant traveling with the sun, a building printer or a zero-packaging supermarket, this book celebrates the energy and imagination of people who want to make their cities a little more fun, clean, friendly, green and above all, restore a sense of community. Our cities belong to us, and they depend on us. Only we can make them worth living in.
