URBAN DEVELOPMENT STRUCTURE
The urban development concept for the new district on the site of the former Prinz Leopold barracks in Regensburg by ISSS research Architekten and Bauchplan Landschaftsarchitekten envisages a classic, space-creating urban structure. The quarter is conceived as a social and ecological model project that is also intended to reduce parking spaces and minimise underground garages with new mobility concepts and neighbourhood garages. The central element is a diagonally running neighbourhood park that connects to existing green structures to the north and south.
The three residential courtyards of Stadtbau-GmbH Regensburg are centrally located directly adjacent to this park and will be the first new buildings in the neighbourhood. They will have a decisive influence on the scale and atmosphere of the neighbourhood in terms of its goals. The opportunity and task is therefore to develop a convincing social, architectural and open-space interpretation of the model project, in which the innovative technical themes fit in as naturally as possible. The block structure in the draft development plan opens up to the neighbouring courtyard or park at certain points. The spatial guidance through the openings was strengthened by emphasising the ends in order to simultaneously increase the potential of flats with three-sided lighting at these points. The openings in MU2 and MU8 were placed at the seven-storey high points; in MU4, the south-eastern development jumps to the park side. Overall, the building depths and heights attempt to shift floor space away from the streets and towards the neighbourhood park.
The high design standards, combined with the goal of a technically innovative model project and the parallel development work, pose a logistical challenge to all those involved, which can only be met with a high degree of teamwork and a solution-oriented approach. Within the cooperation with Maier.Neuberger.Architekten, Palais Mai is dealing with the planning and design of the facades.
ARCHITECTURAL AND DESIGN QUALITY
Taking into account the aspects of sustainability, as well as the time constraints of the project, the development will be realised in a timber hybrid construction. The architectural approach is based less on individual details and more on the interaction of the individual parts to form an effective overall sum. Here, the focus of the design is on the readable joining of these elements, the different structures of the façades, the similar but not identical houses, differentiated building heights, as well as the generous passageways. The colour accents and structures of the cladding, which vary in nuances, the slightly jumping relief of the exterior walls and balconies also contribute to creating spatial density and complexity in the sense of a lively neighbourhood identity. Another defining element is the wide cantilevered roof surfaces and pergolas, which not only serve to technically maximise solar gain, but also make the theme of sustainable neighbourhood supply visible and tangible to the outside world.
The combination of a load-bearing reinforced concrete structure and highly insulated, prefabricated exterior walls in timber frame construction creates economical, sustainable buildings with a minimised CO2 balance. The façade areas in timber frame construction receive rear-ventilated cladding made of recycled aluminium, while the ground floors are finished in mineral reinforced concrete or plastered.
