Former US Army Sites Transform Into 180-Hectare Green Housing Community
Redevelopment across 180 hectares creates new neighborhoods that expand housing options and sustainability features for local communities.
How we reported this
Former US Army sites in Heidelberg are being converted into five sustainable neighborhoods that include affordable housing options, directly affecting how residents access homes and green spaces in the city.
Housing Supply Changes for Local Families
The Neue Südstadt district has delivered approximately 1,100 new and renovated apartments between 2018 and 2025, with another 300 approved but unfinished. This adds to the planned 1,500 apartments across the project while the Rohrbach hospital quarter contributes 600 apartments. These developments replace military land with residential units that include affordable components, giving residents more choices near existing suburbs without relying on distant new construction.
Climate Standards and Daily Living
The nearby Bahnstadt district covers 116 hectares and functions as a carbon-neutral area built to passive house standards, currently housing around 6,500 residents. It serves as a testing ground for Heidelberg's 100% Climate Protection Masterplan, which means new buildings in the converted sites incorporate energy efficiency measures that lower long-term utility costs for occupants. The former US Hospital site in Rohrbach adds 600 units around a 7,000-square-meter park, providing immediate outdoor space that integrates into neighborhood routines.
Innovation Access and Community Connections
The Heidelberg Innovation Park is being constructed on the former Patton Barracks site to support digital age innovation and research. This places research facilities within the new neighborhoods, allowing local workers and students easier access to emerging job opportunities tied to the surrounding residential areas. The overall 180-hectare conversion links these elements into five diverse neighborhoods focused on affordability and sustainability.
City planning documents show the projects draw on former military land to meet housing demand while meeting climate goals. Residents benefit from the combination of completed units, ongoing approvals, and integrated parks that support everyday use rather than isolated development.
Further stages will continue to add housing units and infrastructure as approvals move forward, with the emphasis remaining on integrating the new areas into the existing urban fabric of Heidelberg.
