Studio Animal-Aided Design is a start-up company resulting from research projects on the role of animals for the design of open green spaces. Our aim is to implement the Animal-Aided Design (AAD) method into international planning practice, to promote biodiversity and urban nature within urban development, landscape architecture and architectural projects. The central idea of the Animal-Aided Design (AAD) method is to integrally plan the occurrence of animals as part of the design of open spaces. The practical experience of Studio Animal-Aided Design with the planning of animal-human relations in the context of the application of the Animal-Aided Design method shows that a new conception of urban animal-human relations, e.g. under the guiding concept of co-habitation, is socially possible and can find acceptance. Reasons for this include the adaptation of animal species to the environments of urban areas, the increasing acceptance of the occurrence of wild animals by urban residents and the importance of cities as areas of high biodiversity.
