Concept of urban space in the new Bahnstadt Heidelberg neighborhood
A new neighbourhood is to be created on the site of Heidelberg’s former goods yard which extends over an area of 116 hectares and is one of Germany’s largest urban development projects.
The open space concept is based on an urban masterplan by Trojan & Trojan, which envisages a large proportion of high-quality public spaces with sub-regional appeal and strong individual identities, applying green and resource-saving construction methods alongside stormwater management.
A 9.5-m wide water basin on “Langer Anger” collects stormwater from roofs and courtyards and lets excess water seep into the ground via a system of infiltration areas.
Play areas and lawns abut the main promenade along the edge of the urban development. A seating step mediates between intensively used zones and ecological compensation areas. A long continuous retaining wall made from tamped concrete protects the elevated gardens of the residential blocks. It forms a hard architectural edge that defines the interface between private and public spaces.
