Domus Litonii
Domus Litonii (Latin for "the Litonius house") is a three-story Empire style residential, commercial and office building with a lower bazaar wing located at Aleksanterinkatu 50 in central Helsinki, Finland.
The building was designed by the master builder Gustaf Leander and it was built from 1845 to 1847. Garden wings were added in 1877 and 1880, and a lower bazaar wing designed by the architect Valter Jung was added on the Keskuskatu side in 1929. The facade on Aleksanterinkatu was modernised in 1936.
The building was commissioned by the master draper and furniture manufacturer Jonas Litonius (1810 - 1864), and the Litonius family continues to own and live in the building to this day. The building is the only remaining 19th century residential building in the entire centre of Helsinki.
The building is protected by construction law, and it has undergone basic repairs from 1993 to 2003.
