In the centre of Trikala stands the building that houses the Regional Unit of the Prefecture of Trikala, a public building that over the years has presented problems and faced criticism from residents and visitors of the city. While efforts have been made to revitalise the existing building, these are not considered successful. In this diploma project, we propose the reuse of the building's load-bearing structure, carrying out interventions where appropriate and remodeling the spaces within it, while introducing a new conceptual identity, where the structure is not entirely reserved for the administrative functions of the prefecture, but rather restores the memory of the historic market and the commercial activities that evolved in and around it, aiming to create a center dedicated to activities for people, that are rare in the area. The new interventions open the building to the public, with a strong emphasis on the functions that occur on the exploitable terraces, such as a small multi-purpose court for sports activities, wellness facilities or film projections. The main design principles are the creation of multiple levels, an increase in public spaces, easy accessibility for all and the creation of routes, while an effort is made to highlight the intertwined uses, with part of the building dedicated to work and the rest to leisure, intensifying the diversity of the two identities and ensuring that life is maintained on it even after working hours.
