“A park like a large discontinuous building.” This was the original idea behind Bernhard Tschumi’s design for the “Parc de la Villette” in Paris. While there are many green spaces, the park offers only a very small amount of biodiversity of flora and fauna and reflects the urban character of a huge city. With my project I introduce a new ecosystem to the sealed “Parc de la Villette”. On the one hand, the concept offers space for several plants and animals, while on the other hand, visitors are introduced to the essential topic of species protection in an urban context. This is the responsibility of the new “Species-protection Verein”, which is sensitively integrated into the new system of vegetation strips, along with a Café and a Biolab. The work focuses on the integration of inhabitants, animals, and plants in an urban park. The created concept for biodiversity shows a way to deal with climate problems in urban areas and represents a contemporary transformation of public space.
