Architecture can do more than just build houses – it can shape social change. This book demonstrates how buildings can become catalysts for energy transition, mobility transition, and climate adaptation when they are thought of as part of a larger whole: as places that generate energy, promote interaction, and flexibly combine uses. The Hof8 project in Schäftersheim in Baden-Württemberg demonstrates how integrative architecture can succeed in rural areas: in this pioneering sustainability project, which impressively combines use of space, aesthetics, and energy aspects, an old farmstead was converted into an open ensemble with a variety of uses, modern interiors, and an energy supply that generates more than it consumes. The result of the holistic planning process is a piece of the future that can already be visited today. ‘Solving the Great Transformation on a Small Scale’ impressively shows how a farm in a small village becomes a model for the world of tomorrow – a place where solutions for climate protection, education, innovation, clean energy, and sustainable communities are already being put into practice today. Change begins with the will of those who plan, design, and take responsibility.
