This project concerns the buildings of the era between the wars with residential use, which are single houses and apartment buildings. First, the house is the typical point of architectural production in which international currents and prevailing local attitudes are met, leading to very different and interesting "marriages", without always being easy to trace the various architectural influences and, secondly, the corresponding actions in the past were mainly small-scale, except for the great project of Greek Society for Environment and Culture "Protection and enhancement of the architectural heritage of the 1930s the City of Athens." This indicates how the final stage of my work could be, had I been able to visit all the buildings which I only saw through books and websites. Instead, I tried to put the foundations in order to create a compact, presentable digital file, which provides expandability by adding additional projects.
