D - 68309 Mannheim: Since 2012, five largely mixed-use neighbourhoods have been developed on an area of 94 hectares on what was once the largest barracks site of the US armed forces in Germany, the so-called "Benjamin Franklin Village". Residential buildings for around 9,300 people (4,100 residential units) and around 2,000 jobs are to be created. A 50-hectare park will also be realised. Existing buildings will be used, energy-efficiently renovated and modernised, but many new buildings will also be constructed. The first residents moved in on 31 December 2017, and in December 2019 the number of residents exceeded 1,000. Completion: 2025
Charakteristik: 11 storeys and higher

"Green roofs are the roof coverings of the future. [...] It's hard to imagine that there was once a time when roofs were dead - without life and without vegetation."
