Energiebündel refers to the historical buildings, creating exciting visual relationships. Two independent ensembles consist of a “hollow” and a “platform”. The “hollow” as a communal outdoor space connects three buildings and opens them to the north towards the park. The “deck” connects the three buildings; it offers private outdoor space for the adjacent housing zones and opens the buildings southwards to the “tree path”. Three differentiated high-rise buildings provide orientation for the entire neighborhood.
