In 2013, the University Hospital Freiburg commissions the development of evidence-based design criteria and Qualitative Spatial Concepts (QRs) for the new building of the Children’s and Youth Hospital Freiburg. In the participatory design approach, Vollmer and Koppen worked closely together with users and experts from the fields of medicine, nursing and developmental psychology. The results were completely new solutions that combine patient care and architecture in the sense of a ‘healing environment’. They are presented in this anthology. The anthology was added to the architectural competition as a basis for the design by the Authority for Property and Construction, Baden-W├╝rttemberg. It is the first publication of architectural- or spatial concepts (QRs) that makes its way into a design competition, thus laying the foundation for an evidence-based design for children’s and youth clinics. Gemma Koppen and Tanja C. Vollmer describe in their 3-volume publication the QRs of the University Children’s and Youth Clinic Freiburg, which they developed together with staff, parents and children as well as the clinic management. The anthology is published under the title ‘Unsere Kinder- und Jugendklinik Freiburg. Clinic for Future!‘. (2015, Freiburg i. Br.: INITIATIVE) was published. The individual volumes cover the following topics: 1. living environment of children, adolescents and parents in the hospital, 2. working environment of a children’s and youth clinic, 3. sustainability of a children’s and youth clinic
