Aulis Blomstedt was a strict modernist and a brilliant analyst in his work. He explored passionately the nature of the fundamental architectural concepts, form and harmony, in all his works. He explained that what he always aimed at was simplicity and clarity and he used only few basic geometric elements in his designs. It was Blomstedt who created the theoretical foundation for a discussion about the esthetic principles and social applications of modular systems.
Blomstedt’s principal designs are the residential apartment blocks designed in Tapiola in the 1950s – 1960s, the atelier houses of Suomen taiteilijaseura in 1955 as well as the expansion of Helsingin Työväenopisto in 1959. He branched out from his portfolio of commercial and residential buildings to design some furniture and jewelry and also made graphic art. He was a leading educator and an erudite participant in the discussions in his field. Blomstedt held the professorship of architecture at Teknillinen korkeakoulu and an active contributor to professional publications.
