How can we, together, make our home on Earth in a time of mass extinction, climate change and social segregation? In this book two interplaying housing crises converge. The first concerns affordable and suitable housing for groups unprioritised by the housing market: older persons, students and migrants. The second concerns our home on Earth: science gives us but a decade to avert catastrophic climate change. This book aims at both reporting on research in the project BOOST metadesign and providing hands-on advice akin to that offered in home economics classes. The book starts performing Oikology – Home ecologics, a field of knowledge and practice in times of complexity, messiness and never finished labour of making homes together within Earth’s limits. The exploration of housing development for older persons, students and migrants in a context of sustainability has been carried out during 2016–19 through processes of co-creation in urban and rural parts of Småland, southern Sweden. Metadesign has opened up for a holistic and systemic take on home making that integrates different dimensions of sustainability and moves from the small and local to the all-encompassing. This book is for people who make homes in their personal or professional lives. It imagines an overarching paradigm of home making which starts from relationships. This is exemplified through speculative scenarios, a set of cruxes to be bounced into the planning process, methods for transdisciplinary co-creation and 29 recipes for home making.
