[1] Domenig was born in Klagenfurt, and studied architecture at the Graz University of Technology (1953–1959).
After working as an architectural assistant, he set up in practice with Eilfried Huth (1963–1973), producing buildings in a brutalist vein.
Their temporary buildings for the 1972 Summer Olympics in Munich were colorful and had the rounded corners and playful geometries typical of pop art.
The multi-purpose hall of the Institute of the Sisters of St. Francis in Graz is reminiscent of a tortoise shell and thus is organic architecture.
Domenig's first internationally acclaimed completed work was the Z-bank in Vienna, which signalled a much more expressionistic, counter-modernist aesthetic.
