1st PRIZE The building is located in an area out of the town of Thessaloniki on the main highway. It is a 15000 sq.m. office building in three levels. The necessity of natural lighting and ventilation of the building guided as at the division of the building in smaller volumes. One of our main concepts was the creation of an internal courtyard which would divide the volumes of the building but in the meanwhile it will connect them through a tranquil, secure and pleasant enclosed space. This internal courtyard will be the heart of the building and an interesting and agreeable area for the employees of the building to relax, communicate and meet each other. All the circulation towards the surrounded buildings will be made through this internal courtyard where we suggested the creation of resting spots and a café-restaurant for the employees and visitors.
