The present thesis constitutes with a contemporary design of an animal shelter. Starting from facts about animals different needs of space, light, air and movement needs of, the attempt is made from the small to the large, from the inside to the outside, to develop a modern architecture for the accommodation of animals. From the outset, this is being developed in three-dimensional space, since the vertical freedom of movement was part of the concept from the outset. On the one hand, the background is the imminent closure of the animal shelter in Vösendorf in Vienna. On the other hand, it is questioned whether existing animal shelters adequately meet the needs of animals or whether new forms can be developed. This controversy is regarded as useful by the author, since the necessity of animal shelters is still present and will continue in the future. In the sense of ever-stricter animal welfare laws, but also, and above all, to meet the needs of animals, a continuing concern with the conception of this type is as indispensable as it is in the field of architecture for humans. The draft refers to the Vienna South / West region, as there will be a shortage in the future for an animal shelter.
