The University’s main building, completed in 1956, is one of Alvar Aalto’s most significant works from the red-brick period. The spaces are divided into three sections: the administrative wing, the assembly hall, and the library, all connected by a central corridor. The building is protected as part of the Seminaarimäki complex.

After the renovation, when the University’s administration moved to the administrative wing, the original spatial structure could be restored by removing later-added partition walls. The architectural significance of the library lobby and the library room was emphasized by restoring and opening up new connections to adjacent spaces. Improvements were made to the ventilation of the assembly hall.
