The partially 100-year-old seminary of the Archdiocese of Cologne was to be repurposed. A comprehensive redevelopment aimed to make the building usable as a 5-stream school complex. A key objective was to highlight the unique appeal of the interplay between old and new structures. Particularly noteworthy are the rainwater harvesting system and the BUS-controlled lighting and heating system.
