The concept of urban development is based on the landscape of open spaces with trees (historical Prater landscape) and the building units positioned in it. The sequence of built-up and undeveloped space is the result of the rhythm of several parameters including: spatial edges, rough-determining distances, orientation and interspaces. Due to the bridge connections in airy heights, eye-to-eye connections are maintained and a diversified movement with different room coverings along the lively ground floor zone is given. Places, meadows, landscapes accompany the residents, users and visitors on the fast way through or during a leisurely walk through the district of Zwei Plus. The difference between open spaces and differently equipped places takes place in addition to the adjacent buildings and the surroundings. Use: car parking, green campus with offices, dormitories and residential studios.
