| Notes | "With the aim of realising ecological settlement projects, the 'Initiativkreis Ökologisches Bauen e.V.' is founded in 1989 with the support of the Chair of Housing and Design and the Research Centre for Ecological Building at the University of Karlsruhe. During the search for a suitable plot of land, they came across a plot of land reserved for ecological building in the development plan and owned by the city. The city of Karlsruhe accepts the realization concept and commissions three competing architectural firms to carry out preliminary urban planning. .... In 1991, the 40-strong Baugemeinschaft constituted itself in a legally binding form and founded a 'Gesellschaft für ökologisches Bauen' (Society for Ecological Building). ..... For the construction of communal facilities and the regulation of communal matters after completion, the builders join together in 1992 to form a 'Society for Ecological Living'. ...."
