A former American military base was purchased by a private investor in 2014. Due to this event, the city decided to redevelop the whole area covering 27 ha and to create a development plan for a forward-looking quarter based on an architectural competition. In parallel to the development, information events for the wider public took place. The new quarter will be constructed according to criteria set out by the German Association for Sustainable Construction. Objectives of this plan are also to improve the microclimate, biodiversity, connectivity, social and functional diversity of the district (Ref. 1 and 2). In 2020, construction work had not yet started. Plans are to begin construction in 2024 the earliest and to complete it by 2027. (Ref. 7)

Focus

Creation of new green areas, Transformation of previously derelict areas

Project objectives

-Addressing the urgent need for affordable housing in Karlsruhe. (Ref. 7) -Closely interlinking living quarters and open green spaces (Ref. 1) -Minimal interference with remaining undeveloped spaces, maintaining a high level of environmental quality in these areas. (Ref. 1) -Facilitating a high level of rainwater infiltration (Ref. 1) -Creating a living quarter that is based on sustainable energy and water use for the around 1300 apartments and 2600 inhabitants of the new quarter. (Ref. 7) -Creating places of exchange and recreation for residents, including children and elderly people (Ref. 1) -Creating space for commercial activity (Ref. 1)

Implementation activities

There was a first information evening for citizens and interested parties as early as summer 2014. (Ref. 7) An urban development competition for the planning of the project was carried out in 2015 and the implementation of the plan is expected to begin in 2024. (Ref. 7, 8) The spatial development considers environmental, ecological and sustainability aspects. The concept is based on having a quarter island in the middle of a park area and next to a national park. The adjacent wilderness space in the national park on the former airfield will be conserved by fencing it and prohibiting access for residents while at the same time a green corridor is created with a park area right next to it for recreation. There, natural wilderness areas will exist next to cultivated green providing habitat for species; at the corners of the park, natural rainwater infiltration systems will be erected. So-called "park windows" facilitate air circulation and provide views for residents on the adjacent park area. Furthermore, water bodies are implemented in the built areas for cooling, the same applies to tree alleys & green islands in public space which also enhance the living quality in the quarter. The implementation of commercial facilities is expected to strengthen the local economy (Ref. 1).
