The main concern of this thesis is to build a new unit at the main train station in the area of Attica (Larisis Station). The main reason of choosing this subject is the need of the existence of a building that would be able to become the main entrance of the travelers that would visit the country. Moreover, trying to create a very big public building like this one in a very dense city, was certainly challenging.

 The main function of the train station is concentrated not only on the transportation of the mass but also on a more poetic and romantic aspect of the human behavior. This place reflects meetings and separations, the start and the end of an experience, the starting point of the urban, and also a landmark for the city. Nowadays, it is a public belief that train stations are aligned to movies, novels and other artistic cre- ations and hold a very close relation to each and every one.
 

 The main concern consists of (a) the satisfaction of many multiple functional needs with the best architectural plan. The location where the unit would be, was very hard to decide because the building would also need to host several public functions (b). The main purpose of the aforementioned is to build a train station that could be a part of the city. Furthermore, through planning, I try to revise the unprivileged area where the unit is going to be built. Consequently, the third concern rises; the need to create an urban plan (c), where the city itself influences and forms the main building and makes it part of the whole.
