The starting point of this wonder that leaded to the project of my diploma is the research and the analysis of two specific areas. The one area is the variability of the constructing procedure and the other is the flexibility that is offered to the requirements of the building’s program at each time. Meanwhile, during the concept of the project, some new researches and questions arose that had to be faced in the limits of the project, in order to reach a totally integrated designed product. The way of approaching and achieving that target is done through the creation of a guest building (or house) for foreign students in the district of Psirri in Athens.
