We try to enlarge the boundaries of the building discourse through non-orthodox, interdisciplinary and unusual ways of working. One of our core competencies includes building in historical context and the sensitive handling of existing buildings. We work on design tasks from urban planning to the smallest sanitary facilities. The architecture office Lechner & Lechner was opened by Christine & Horst Lechner in 1987 and re-founded in 2015 as lechner-lechner-lechner ZT gmbh. In the course of the collaboration with the Chair of Urban Development at the ETH Zurich at the end of the 1990s, we met the architect Johannes Schallhammer. Since 2000 we have been working together in an office community at our common location in Salzburg's Priesterhausgasse. In addition to our own projects, we work on many projects together.
