The subject of this thesis is the proposal of an observatory building group as well as a refreshment stand in mountainous region of Kastoria. The organization of the building and the configuration of the environment space, are the main concerns of the proposal. Elements that influenced the study are the incorporation of the most modern technological applications as well as the harmonisation with the particular character of the region.

However, in order to create guiding lines that they will help the study of the observatory, a reference of the achieved targets of the building should be done. To this direction the first thing to be mentioned is the protection of bodies of observation as well as the general mechanical equipment. The ergonomic design and the insurance of comfort for the observer are certainly required. Climate and ground’s configuration in the region play a fundamental role in the choice of locality for the observatory’s construction. It is necessary to ensure the good visibility of the sky. At the same time, a building like this should be away from sources of artificial lights.

The bulging should be adapted to the microclimatic conditions of the surroundings, with a great consideration to the construction materials. The building is supposed to acquire the exterior temperature as rapidly as possible, while simultaneously the observer should be protected from unfavourable meteorological conditions. The materials of the construction should not influence the atmosphere around the building.

Finally, one of the studied subjects is also the form that the observatory is supposed to have, in order to combine the functionalism and the facility of manufacture. The ways that the building’s roof is removed are important, as it concerns the entire roof to one direction or its individual parts.

This version of rolling roof has been selected in the study. The space of observation has rectangular provision and the roof rolls on two parallel joists. The logic of parallel joists determined the general provision of the entire building group. Rectangular levels are placed in parallel. Between them linear “walls” exist. A sidelong way crosses the entire group. It begins from the parking and leads to the refreshment stand cutting the parallel lines that defines the buildings with the “walls”. The proposal is completed by two curved corridors in the perimeter of the building group.
