The diploma project is dealing with an area which is surrounded by two main streets of Thessaloniki, named Kassandrou str and Olympiados str that form an arc. While moving from the city center to the upper city and vice versa, this area comprises a boundary. Main goal of this diploma project is to redefine the site, by proposing different methods of urban design strategies that will result to the improvement of public spaces. Another goal, of the same importance, is to redesign the site in such a way that it will no longer behave as a boundary between the Upper City of Thessaloniki (ANO POLI) and the commercial city center.
 A network of pedestrian zones is constructed in order to ensure a smooth flow of movements on ground level. This network is a link among historical landmarks of the area, hub points and main movement axes of the city. Uses of land that are scattered in the research area are reorganized and redistributed. Single unit dwelling is amplified, transformed, under the form of internal zones, and placed on higher levels of apartment buildings. This transformation carries characteristics of the ground level to these higher placed internal zones.
