The object of the present work is the design of a theater museum and a closed, indoor theater, in the municipality of Heliopolis, in the prefecture of Attica.
The municipality of Heliopolis has a large outdoor theater, the Alsos Theater «Dimitris Kintis», in which a number of events are organized during the summer season. So far no one was able to send in the perfect solution, which is not strange. The idea for this dissertation arose from this need.

In order to properly and comprehensively study the design of the required building program, visits were made to museums and theaters in Athens.
Also the collection of the necessary data emerged from the research in the town hall of Heliopolis as well as in the technical service of the municipality of Heliopolis. The historical archive of the municipality collected a lot of historical information and rich photographic material, which depicts what the city was like in the past.

An accurate topographic copy and additional technical-legislative data concerning the study area were provided by the technical service of the municipality.
Thanks to the interviews provided by residents of Heliopolis, their needs were realized and how they envision a public space, capable of housing their entertainment activities.

Specifically, the work includes:
a) Historical data about Heliopolis and photographic material from the city.
b) Elements for the design of the city, illustrated with the help of maps.
c) Initial ideas for the design of the building.
d) The final plans of the building.

The aim of the work is to design a museum-indoor theater, which will be a point of concentration and relaxation. A building integrated in the urban fabric, with easy access from all parts of Heliopolis, that meets and serves the needs of its residents.
