Architecture impacts everyone. We develop our projects with expediency and passion, anticipating future developments, in participatory processes, by linking together new contexts and asking unconventional questions. Architecture always means working for and with people, with the aim of developing shared habitats.

ostertag ARCHITECTS was founded in 2000, in Vienna, as a team of architects, project developers, and engineers. The wide spectrum of projects includes the planning of residential, office, and commercial buildings for public and private clientele, as well as cultural and educational facilities. In addition, our work comprises a large number of multi-award-winning multimodal transport hubs, urban infrastructure projects in Austria and abroad, new construction and modernization of railway stations, and bridge design. With our expertise in mobility planning, which has grown through years of participation in research projects, we have made a name for ourselves in Europe with mobility operators.
