The Project focuses on the adaptation of the administrative building of the Mercuria Foreign Trade Company from the 1970s. Often associated with the communist political regime of Czechoslovakia, this architecture typically evokes mainly negative feelings in a society. However, buildings from the Brutalist period in Prague fundamentally shape the image of the city and represent an important layer of architecture. Therefore, the hasty removal of these buildings and their replacement with new, often questionable architectural objects is gradually erasing the building culture of this period. The thesis project seeks to breathe new life into a now obsolete but valuable building by changing its use into shared (cluster) housing, spaces for work, gathering and other public functions.
