Parkstadt Süd is located on the inner green belt of southern Cologne. Urban Catalyst studio and neubighubacher architects facilitate the cooperative process to develop an idea of the "Parkstadt Süd of tomorrow". With a series of talks and events in different formats, as a market place of ideas or walk-in-models, we involved a broad range of citizenry. Within the process an attitude towards the development of Parkstadt Süd was agreed on. This attitude fits the locality as conflicting positions were translated into spatial vocabulary and results led to an integrated spatial planning.
