His studies revealed another talent, namely, Laube’s ability and desire to share knowledge, which was recognised by the management team of the Riga Polytechnic Institute and, after graduation, the young architect was offered a position as a tutor. In 1907, the Laube Architecture Workshop was established, which operated successfully until World War I, creating nearly 30 building designs a year. During the war, the Russian Empire moved the Institute to Moscow and Eižens Laube followed, too. Due to the lack of design work during the war, Laube started writing articles and books, including The Art of Colours and Shapes.
Once Latvia became independent, the search for Latvian style in architecture began and neoclassicism emerged as the style that most accurately expressed the honour and pride of the new nation with its pure forms and lines. Laube was one of those who helped to define it. During Latvia’s independence period, the architect was more involved in academic work, leading one of the workshops of the Faculty of Architecture at the University of Latvia, participating in urban planning, chairing the Architectural Commission of the National Building Committee and designing buildings of national importance such as the Latvian Academy of Agriculture, the Ķemeri Sanatorium and the reconstruction of Riga Castle.
World War II forced Laube to emigrate to Germany, where in 1946, together with other great architects from Latvia, Estonia and Lithuania, he established the Faculty of Architecture and Engineering at the Baltic University in exile in Pinneberg. He spent the last years of his life in Portland, Oregon, where, reflecting on his accomplishments, he published a collection of articles titled Writings on Architecture.
