Most of Pirchan’s architectural designs arose between 1905 and 1910; they evince an architectural language that was strongly influenced by his teacher Otto Wagner. Among other things, they depict country houses, monumental buildings such as a mountaintop necropolis in Trieste or a Schiller monument for which he received the golden Fuger Medal, a crematorium, a pilgrimage church and a restaurant, as well as a recreational facility for workers—and much more.

But Pirchan also turned his attention to interior design and later focused increasingly on innovative ideas: for example, in 1915 a so-called world-format house; from 1925 buildings made from Solomite (straw pressed into the form of panels), with which Le Corbusier also experimented; and ca. 1930 the futuristic design for a theatre in South America. His training as an architect later served him well during his work as a set designer.
