Theodor Körner Hof, Public housing complex in Margareten, Vienna, Austria

Theodor-Körner-Hof is a municipal housing estate in Margareten, Vienna, built between 1951 and 1955 by Ladislaus Hruska and Kurt Schlauss on the site of a former hay, straw and horse market. It contains 1,356 apartments in post-war block construction, the largest such estate in Margareten. At its centre stands the 20-storey Matzleinsdorfer Hochhaus, 60 metres high.

The complex was built between 1951 and 1955 on a former hay and horse market site by architects Ladislaus Hruska and Kurt Schlauss. The project was part of Vienna's post-war efforts to provide much-needed housing for the growing population.

The complex is named after Theodor Körner, who was mayor of Vienna from 1945 to 1951 and then federal president until 1957; he was a Social Democrat, not a poet. The name ties the municipal housing to the city's postwar social-democratic administration.

The site is easy to navigate on foot with multiple pathways winding between buildings and through the green spaces. A tall noise barrier installed in 2007 shields residents from traffic while generating power through integrated solar technology.

The noise barrier incorporates special glass panels designed to prevent bird collisions while generating electricity simultaneously. This innovative combination of environmental protection and renewable energy makes the installation a pioneering example in Vienna.
