This particular thesis concerns the creation of a guesthouse of mild tourism. The area of study of the above guesthouse is the island Prasouda of South of Pelion. The size of the island is 7,000 sq.m. and the closest distance from the main land is 800m. The island is easily accessed from the villages: Marathia, Melina and Horto. What makes Pressouda particularly special is the dense vegetation and the abandoned monastery Zoodohos Pigi built on the 11th century. The peculiarity of the above gesthouse lies with the monastic style of habitation. Beyond the agrotourism and the different activities that can be developed in nature cetain principles met in the monastic life are also kept here. Although the complex resembles quite with a simple guesthouse, the objectives of life are slightly different. This is why certain rules are followed and are listed below. The result of this effort is a blend of physical activities, public life and retreat. As for the part of activities the island of Prasouda is ideal for fishing, diving in underwater caves in the area and any type of physical activity that requires calmness. Apart from that it is mandatory for the guests to perform some social work either in cleaning up the coasts, or taking care of the olive trees. The way this idea comes to life into a building complex, is the creation of a simple cell which is recreated around the island and a main building that includes all the supportive uses. Obviously, the administration of such landscape could not be other than a mild formulation of a traffic network. The construction of any premises is studied with the perspective view of creating a minor print on the environment.
