The present diploma thesis approaches the concept of co-living, in a contemporary model of social housing. It concerns the restoration and reuse of the refugee building complexes in the area of Agios Nikolaos in Kaisariani, as well as the redevelopment of the entire area that incorporates them.
Kaisariani was more developed after the period of the Asia Minor Catastrophe, when the area received a large part of the refugee stream that flowed to Greece. Gradually the refugees were transferred from more unsettled forms of housing to new apartment buildings designed with the principles of modernism, which were also a typical example of residential complexes with buildings of more coexisting households.

 After insufficient development actions, the public area still needs to be re-designed and upgraded, while the refugee housing complexes seem out of place in relation to the newly built and densely populated environment that surrounds them. The new apartment buildings that are being built in the area to meet the modern housing needs have resulted in the alteration of homogeneity, and ultimately the identity of the settlement.
The proposal aims to serve a homogeneous population (related to the University), the creation of a community, and the evolution of the old structures, in order to respond to a modern model of collective housing.

 Specifically, it includes the creation of new routes for the better connection of the selected complexes with the urban fabric, the remodeling of the internal common yards, the restoration and reuse of as many refugee blocks as possible. The proposed additions and configurations will serve the residents of the apartment buildings by offering more spaces for meetings, joint exploitation, while at the same time they will invite visitors to joint activities that will be developed in the area. The new operating conditions in the complexes help to redefine the relationships of people with each other, as well as with the residence and the outdoor space in the city.
