Alexander Diem studied architecture in the class of Hans Hollein at the Vienna Academy of applied Art. Diem then went to work at the office of Viennese architect Gregor Eichinger as well as for Caramel Architects. Since 2011, he had had his own office, which focuses on the issue of building culture.
Turning away from absolute subjectivity, Diem wants to turn toward defining and identifying common needs, themes and issues. Of central significance is the issue of privacy. One of the guiding questions is what users should, or want to, reveal of themselves. The Diem office always wants to say a friendly hello to the built environment but engage in a discussion with it.
