50825 Cologne-Ehrenfeld: approx. 4 ha area. Within the framework of a cooperative expert procedure, three planning offices developed an urban development plan in autumn 2013 as a basis for the further structural development of the area. The design by Ortner & Ortner from Cologne was selected as the winning design. The citizens wanted housing and culture instead of a shopping mall. The shopping mall was averted. Instead, the partly built-over and used, partly fallow area in the centre of Ehrenfeld is to be developed integratively. In addition to the Helios primary and comprehensive school (Groundbreaking was in Dec. 2019; both schools are expected to open for the school year 2023/2024 completed), a lively mix of housing, culture, commerce and retail is to be realized there.
