Markus Zilker, born 1975, studied architecture at the TU Vienna and ETSA in Seville. After practicing in Vienna and Campinas/Brazil for a few years, he established the einszueins architektur studio with Katharina Bayer. Their work focuses on communal building and living. In Vienna and the surrounding area, they have realized many joint building projects such as the Wohnprojekt Wien (Engl.: Housing Project Vienna), which is home not only to Markus Zilker himself, but all his studio space as well.
