Richard Gach completed the Salzburg HTL for Building Construction and in 1949 he studied architecture at the Academy of Fine Arts Vienna in the class of Lois Welzenbacher.

[3][4] During his studies he became friends with architects such as Gustav Peichl, Friedrich Achleitner, Wilhelm Holzbauer, and Hans Puchhammer.

[6] This concept is typified by the residential complex Edergasse 1-3 in Vienna 21 and the two high schools Hernalser Gymnasium Geblergasse and Amerling-Gymnasium.

Built in 1970-1972, the new building with 24 classrooms and two sports halls corresponds to the common typology used in the construction of secondary schools in the late sixties, without any architectural respect for the environment.

[9] Richard Gach was also active in Lower Austria, as reflected in numerous construction projects such as the Aufbahrungshalle in Orth an der Donau, the Bundesgymnasium and Bundesrealgymnasium Amstetten (high school), the Sparkasse Mistelbach and the Hauptschule Gars am Kamp.
