Marmorek worked at the Exposition Universelle (World's Fair) of 1889 in Paris, where he was duly impressed by a colorfully-lit fountain aptly called the Fontaine Luminuese.
Subsequently, he designed a scaled-down version for the park northeast of the city center between the Danube Canal and the Danube River called the Prater, where the 1873 Weltausstellung (World's Fair) had been held.
The success of this project meant that he soon became one of the most sought-after exhibition architects in the city, being charged with the design of the exposition Alt-Wien ("Old Vienna"), also located in the Prater.
In 1895 he was hired by the theater director Gabor Steiner to design Venedig in Wien ("Venice in Vienna"), one of the world's first theme parks, for which he was repeatedly called on to remodel pavilions whose purposes and amusements frequently changed.

Also beginning in 1895, he also helped distribute the new magazine Neubauten und Concurrenzen in Österreich und Ungarn ("New Buildings and Competitions in Austria and Hungary"), which would soon provide the Wagner School (the students and followers of great Viennese modernist architect Otto Wagner) with a major outlet for the dissemination of their work.
Though Marmorek was himself not a student of Wagner, he was happy to make considerable use of Wagner's influence in his later work.

Marmorek married the painter Nelly Schwarz in 1897, and in 1898 Marmorek he built the Nestroyhof in the Leopoldstadt district of Vienna, near the Prater, for his father-in-law Julius Schwarz.
In 1902 he completed his most famous structure, an apartment house known as the Rüdigerhof on Hamburgerstraße in the Margareten (5th) district of Vienna.
