The building was designed by Engineer Edoardo Cherubini with an estimated cost of US$800,000. The edifice had three floors and a basement. The basement housed the kitchen, laundry room and crypta. The first floor included the chapel and sacristy, the reception, the refectory, lobby and recreation room. The second and third floors were divided into classrooms and dormitory spaces.
     A separate house was also set up for the Sisters.
     Today, the Collegio has rooms for 55 priests.
