Europan is a biannual, pan-European competition that aims to promote the realization of innovative ideas by young architects and urban design professionals on various European sites. The winning scheme for the Heidelberg site ‘The Red Ribbon’ redefines the waterfront of Heidelberg’s University Campus, the Neuenheimer Feld. The project gives the Campus an appropriate presence within the context of the city and establishes a coherent, public and accessible river frontage. Besides the landscape design for the riverfront it proposes a reorganisation of the urban layout of the Campus and the addition of 3 key buildings to the site: Römerlawn, Neckar Island and Biodiversity Centre. A total set of 23 autonomous yet complementary actions supports a phased and flexible implementation.
