Angelo Ferrara is architect in Juri Troy’s office. This is a multidisciplinary studio, founded in Vienna in 2003 and located also in Bregenz, in the Vorarlberg region. The close contact to craftsmen and to the regional art of timber construction of Vorarlberg have been two essential factors for the definition of the fundamentals of research. The holistic and sustainable approach to architecture leads us to use natural and local materials, to resort to traditional construction techniques deeply-rooted in the places. The daily practice of the architecture has brought to excellent results like the realization of the first carbon neutral house of Austria, the “Michael Grzimek School” in Frankfurt, that won the Greenbuilding Award, and other visionary timber-project with highest energy standard.
