The Wüstenrot Insurance Center (1989–1992) by Josef Lackner is currently Salzburg’s youngest landmarked building and a seminal work by the architect. Created during a period of profound social and technological upheaval, it blends a postmodern formal language with technoid aesthetics and structural logic. Lackner’s concept was an early response to the demands of a computerized workspace, introducing an innovative office typology through its unique light and spatial design. Since being granted protected status in 2021, the building has become a focal point for heritage conservation discourse. Starting in 2024, the structure has been undergoing a phased transition to new uses. The resulting architectural measures demonstrate how the treatment of “younger” building stock involves a delicate balance between functional adaptations for today’s office requirements and the preservation of original architectural and design qualities.
