The official residence of the commandant of the Imperial Finnish Cadet School was completed in 1863. The building was designed by Ernst Bernhard Lohrmann, from the superintendent's office. The red brick building mainly represents neo-Gothic style. The first director to move into the building was Major General Edvard Gustaf af Forselles. Three commandants of the Cadet School occupied the building. Edvard Gustaf af Forselles was the commandant from 1863-1871 and after him Lieutenant General Frithiof Alfred Neovius from 1871-1885. The last owner of the house was Lieutenant General Carl Enckell in 1885-1903.
