ERLINSBACHERSTRASSE, AARAU , 2022, 1st PRIZE
Directly on the banks of the Aare, between Erlinsbacherstrasse and the Kraftwerkskanal, a mixed-use and sustainable development with 60 to 70 rental flats will be built from 2024 onwards. The twin houses of the new chain of buildings are positioned in such a way that heterogeneous spaces are created in between, ensuring permeability and open spaces. The ground floors accommodate community rooms, a day-care centre, and commercial units. A bistro is also planned to provide a meeting place for the new residents and enrich the neighbourhood. All the buildings have been moved away from the noise-critical area facing the Aare, meaning that costly noise-reduction measures are no longer necessary. The three- to four-storey houses are designed as timber frame constructions with staircases made of prefabricated clay cast elements. The use of concrete as a building material is to be avoided to the greatest possible extent. A ground-source heat pump in each building and photovoltaic systems integrated into the roofs and façades supply the residential ensemble with energy. All flats boast views to two or even three sides and thus benefit equally from the attractive riverside location. The living concept is based on a simple system of use-neutral rooms around a central living space. This makes the same type of flat work for a family with many children, for a couple working from home or even for people sharing a flat.
