While the livelihood opportunities in the refugee camps in Northern Greece are not sufficient, the city center of Thessaloniki represents a huge potential for integration, benefiting both existing citizens and newcomers. There is a large potential in the vacant buildings, the empty ground floors and the unused spaces in the city. How can this be transformed architecturally into common structures for both current and potential citizens?The scalable system of the project is a potential strategy for rethinking the ground floor space, support the existing decaying building structures and utilize unused space. The aim of the project is to secure long term integration of displaced people while the implemented structures improve the livelihood opportunities in the existing neighborhood.
