His first important work was Moraitis house in Tzitzifies (1921-1923). In 1932, upon the completion of the Elementary School in Pefkakia of Lykavittos, he came to the realisation that his works were not satisfactory and changed his aesthetic perceptions. All of his subsequent architectural works were based on the idea of bridging universalism with regionalism. In the 1940s and 1950s, his architectural creation was limited to designs for graves. However, in the following period, from 1951 to 1957, he was involved in many projects. Among them is the formation of the archaeological site around the Acropolis and Philopappou hill, perhaps his most important work, and the tourist pavilion of St. Demetrios Loubardiaris, seeking its ideal. In 1958, after 35 years of NTUA as a professor, he retired. In 1966 he was elected a full member of the Academy of Athens.
