Steinbach am Attersee is the largest municipality in the district of Vöcklabruck in terms of area, yet the municipality has only just under 900 inhabitants (main residence). Due to its beautiful location directly on Lake Attersee, the pressure on housing is great. Creating more single-family homes is not an option for the municipality. However, there is hardly any affordable housing available (for young people). On the other hand, there is an ageing population group with generous living space that is increasingly dependent on the help of others. There is a lack of suitable offers for both interest groups. Steinbach am Attersee would like to create a joint response here with ONE innovative housing concept.
