 In cooperation with Anton Battigelli, in 1898 Herz carried out extension work on the building of the Austro-Hungarian "Rudolf" Hospital (Ospedale Rodolfo in contemporary parlance) in the Abbasiyya quarter (9a Sharia al-Masud off Midan Abduh Basha).The building, of modest quality, has been remodelled several times since; in 1997 it was the property of the Faggala Evangelical Church and housed an outpatients' clinic, a vocational training centre, a Christian club and offices.The "Cairo Street" at the World's Columbian Exposition of 1893 in Chicago was designed by Max Herz and he also supervised the final stage of its erection on the spot.
