We explore, analyse and experiment; we visualize the latent questions of a project; we challenge established ideas and generate new ones in the process. Andreas Rumpfhuber was and is involved in a series of international research projects, both initiating and leading them. They are the scientific basis for the architectural projects of Expanded Design. In his reseach, Andreas Rumpfhuber questions established formations and terms. He does this as a theoretician and as an architect. This dichotomy leads to a specific research practice in which analysis and development join together.
