Description of the project: 

The residential concept aims at the promotion of social relationships, which are expected in the designed communal areas, such as ‘market place’, ‘garden’ and ‘roof’. In accordance with an innovative, multi-generational model, the residential complex satisfies the requirements of all age groups, through the flexibility of single units, which allow for adaptation to different resident requirements. Conceptual diversification of floor plans, as well as ecological and technical measures support the creation of a vital and safe residential network as a trendsetting approach in sustainable social housing. The complex is completed with commercial areas on the ground floor, as well as office spaces facing the courtyard. This meaningful variety of space utilisation enhances the interaction and communication between residents, users, and their immediate environment. The building structure follows a free zoning concept, which defines the additional rooms level of privacy. The lively, homogeneous, and memorable façade is achieved by carefully selected components, accompanied by varying materials and rhythmical structuring.
