The site, located north-east of Augsburg's old town, is found at the intersection of a residential area characterised by development from the turn of the last century and the busy Dieselstrasse. For many years, the perimeter was dominated by halls for the manufacture of heavy cranes - a place of creation and work. But at the same time, the closed, flat hall structure of the factory site formed an extensive "terra incognita" within the urban space.
With the relocation of the production and the desire for a change of use of the site, the need for a rededication of the existing atmosphere of the place also arises. The consolidation of the existing residential area in the south should benefit from this as much as the new residents. It is therefore necessary to analyse the urban spatial preposition and to preserve and strengthen formative elements. This concerns spatial layouts and proportions, neighbourhoods and references, as well as existing buildings worth preserving. The design proposes a structure that is made up of buildings with familiar dimensions, or preserves valuable existing buildings that are characteristic of the locality. Thus, the residential building on Schallerstraße and the northern part of the long, eastern assembly hall are to remain.
Like the existing buildings, the new settlements are oriented in a north-south direction and thus create two-sided residential sites oriented to the east and west. To the north facing Dieselstrasse, these five- and six-storey houses, together with the characteristic façade of the existing hall, form stately "character heads" connected by recessed, less deep building elements. The resulting open spaces are clearly directed but interconnected to form a new structure. A wide, tree-lined courtyard in the west creates a calm green atmosphere, while the second character courtyard space in the east is conceived as an urban space that can also be understood as a public passage. In this way, the new quarter is connected to the northern neighbourhoods. Finally, the building that replaces the southern part of the existing hall allows a spatial link with the existing open space of the neighbouring development along Schaller Straße. The new building blocks are characterised by residential use on the upper floors. In the northern part of the existing hall, there is an offer of communal use for the entire neighbourhood. The existing wall is shortened somewhat, but continues to serve as a noise barrier to the eastern petrol station. It also defines the forecourt area for community use. The southern part of the preserved hall structure is repurposed for a specific typology of housing.
FROM THE JURY REPORT:
The design retains two of the existing buildings (hall to the north-east and residential building Schallerstrasse 3), which are complemented by a series of individually distinctive structures grouped around two essentially north-south facing courtyard areas. The result is the impression of an evolved urban building block in keeping with the scale of the surroundings.
The differentiated courtyards are easily accessible from the flats and allow passage in both east-west and north-south directions.
The proposed appearance with rendered façades and the alternation of stepped, eaves and gable buildings along Dieselstraße makes the planning look very appropriate for residential use.
The installation of flats is proposed for the existing hall. The implementation of this idea, whose charm is expressly appreciated by the jury, is, however, subject to a feasibility check with regard to an investigation of the structural substance and economic feasibility as well as the building code approval capability of the change of use.
The dense building structure requires a ground plan orientation of the middle house to the west. On Schallerstraße, the right-angled extension to the existing building tends to create an unfavourable corner situation. The distance to the second new building, which closes the eastern courtyard to the street to the south, is probably too narrow for pleasant living in the proposed form. The necessary access for the fire brigade to the western courtyard would also probably make it necessary to reduce the dimensions of the building in favour of the open areas, and the planned tree plantings would have to be reduced. The underground car parks are too small and would have to be enlarged. The proposal has the highest use figures of all the submissions, so a reduction in density seems possible in principle.
Overall, the design has the potential to create a residential complex that is appropriate for Oberhausen and creates an identity. In the eyes of the jury, the foundation's goals of family-friendly and intergenerational living can be implemented well here.
