Interspace, a project to modify unused spaces in cities. Due to the immense demand of urban living space in inner cities, I searched for ways to interact with the remaining areas instead of taking away existing green or open spaces. In cooperation with Felix Zanger, I did a research project and created a catalogue of spare spaces in Düsseldorf. As a result, I picked one of these places for my master thesis to develop urban living space. The design bases on an algorithm and a grid system which creates a unique structure. Several sizes and shapes of apartments are possible. A passageway on the ground floor remains and creates a connection between the street and the park. In order to enliven the neighborhood, various stores are created. The building is planned in a cross-wall construction of reinforced concrete. On the upper floors it is supplemented with walls in timber construction. Additionally, since we are living in the age of a fast-paced communication and speeding society, a buffer space to rediscover nature and slow down time becomes a must-have feature of our urban environment. I assured every apartment their own terrace and created the concept of an outer shell, shielding the outside world and keeping a regulated temperature inside the hull. To reinsure an individual ventilation in every apartment, parts of the facade dock on the outer shell. A lot of community space is created with the large access system and the roof terrace with a greenhouse. This is where community and commitment to one‘s own district is created.
