Central Business District project is at a strategic location along the port with facing sea. This strategic location and key requirement of making the project iconic is the most important requirement. Thessaloniki is one of the important cities from a growth perspective with lot of potential in becoming Europe’s urban node. The key factor is to tackle with the underdeveloped west part of the city where the port is located. At the same time, this is a very attractive location for developing the dilapidated area into a new growing urban hub for the city with expanses of the view due to flat portion of the site. The exciting brief with multifunctional activities under one roof was equally challenging and engaging to participate in the competition. The first concept was formed in order to understand why and how to make the existing buildings as a part of newly built forms and integrates them as a one functional unit. In The process, characters and function of the buildings were understood and the energy they carry along was equally important from a decision of alteration of function. This was the primary starting point for the projects as these buildings are located at different locations on the site. We identified pockets in between these existing building and identified zones which have the most potential for important functions. These zones were marked with a hierarchical placement of masses with separating them functionally. The concept was to keep the masses at eye level for a better relatability for pedestrians and making a connection with the city.
