The topic of the diploma thesis is the restoration and the change of use of the existing industrial complex of KOMDE (Vehicle - Machine and Public Construction Center), which is located in the town of Trikala. Since 1963, a construction site has been developed within the buildings of the complex for the drying processes of the lakes in Thessaly. Nowadays, however, it is used as a parking place for the cars of the Prefecture of Trikala. The aim of the paper is the construction of a new university campus that will serve for the accommodation of the town’s two T.E.I s (Technological Educational Institutions). The industrial complex consists of eleven buildings, four of them are reused and they manage to maintain their form, whereas the rest of them are demolished. In addition, a brand new building is created in order to cover the institutions’ needs while at the same time it could be used by the municipality of Trikala. The need to connect all the buildings together led to the construction of exterior corridors and a main entrance made of a mild metal structure. Therefore, the new operational needs are adjusted to the buildings’ typology, maintaining the operational continuity and the area’s historical memory.
