Lichtlabor Bartenbach (Bartenbach Light Lab)
Architecture: Josef Lackner (1988) Builder-owner: Bartenbach GmbH Open to the public: by appointment only. Accessibility: Road from Aldrans to Rinn. The adjacent building is the Bartenbach Light Academy by Volker Giencke (2003).
This singular building, for a very innovative light-planning company, was designed with the interplay of function and surrounding landscape as a starting point. The building lot and the road are at very much differing levels, so Lackner carved the laboratory building into the slope, topped by a cylindrically shaped staff building with an entrance at the medium level. Starting from there, two "office spirals” – every workplace at a different level, but with generous daylight – lead upwards and downwards, covering the height of two floors in either direction.
