Hönigsberg &amp; Deutsch was an architecture studio and construction company formed in Zagreb by architects Leo Hönigsberg and Julio Deutsch, active between 1889 and 1911. They produced over 90 known works in the Lower Town area of Zagreb, built during the redevelopment in the years following the 1880 Zagreb earthquake. The majority of these were residential houses, but they also designed manufacturing plants, synagogues and public institution buildings.
