Osnabrück, Germany

Opening up a former freight yard

Team Blauraum, Karres en Brands and Green Box have won first prize in the competition for the development of a 22ha former freight yard area, Lokviertel, in Osnabrück, Germany. Our proposal The Green Loop transforms the disconnected area into a new sustainable neighborhood of the future, connecting it on multiple levels with the rest of the city. 

Lok-Viertel’s vicinity to Osnabrück’s Central Station makes it potentially one of the most important gateways to the city. Due to its past use, the transformation area has traditionally been an isolated area. Numerous visible and invisible boundaries, from train tracks, roads, water bodies, and earth layers made the area appear as a foreign area within the urban fabric. Our priority was to break down these boundaries and integrate the area into the urban fabric while preserving the identity of the site.

Zooming out on a wider reach, far beyond the planning area, the green ecological framework of Osnabrück is strongly visible. Like green fingers, they extend almost into the area and end in the Hasepark. Together with the Hase river, they form the basis of the green loop, extending the biotope and local recreation area into the heart of the site. The river functions not only as of the main connecting element of the two worlds: the historic city center of Osnabrück and the new LokViertel district, but as well as a scenic route through Osnabrück, crossing numerous sights. The new Heritage loop expands this route, leading to other exciting highlights hidden within the LokViertel area. 

The architectural heritage of the Lok-Viertel, the so-called hidden gems, act as anchor points for the new quarter’s identity and serve as key elements within our proposal. Combined with newly built structures, the story and history of the place unfold. The period of industrialization and the extensive use of the area is used as a starting point as part of a new narrative in dealing with resources and nature. The old freight station, currently weathered and taken over by nature, is transformed into the green heart of the new district - the central park. Part of the station's platforms and warehouses are being preserved and will be reused for the central market, an event hall and a greenhouse, to stimulate local urban food production. 



The design reversed the challenges of a disconnected island, within a network of roads and train tracks, and created the foundation of a 15-minute city concept. Within 15 min, everyone should be able to reach everything they need for life from their apartment on foot or by bike – from the workplace, through shopping, to culture. This is achieved through two main elements – the mobility loop and the green loop. Two mobility nodes placed at the beginning of the mobility loop provide parking space for all motorized traffic, keeping the inner part of the quarter car-free. From this point, the Ring Boulevard acts as the main link, providing space for zero-emission and autonomous vehicles. On the other hand, the Green Loop bundles the pedestrian and bicycle paths and connects them to further surroundings.



The basis of our robust framework is defined by the linear character of the distant views framed by train tracks. This simple but clear grid provides flexibility for the unknown future and leaves room for innovative programs and typological diversity. The new Lok-Viertel neighborhood will show resourcefulness at every turn. From e-mobility, through solar panels, to rainwater retention. Ultimately, this abandoned site will become a vibrant and diverse new neighborhood where innovation and sustainability are promoted in all aspects.
