Kosta glashus, Glass construction in Kosta, Sweden
Kosta glashus is a glass structure in Sweden with transparent walls and heated floors built with modern design principles. The building consists of five L-shaped units arranged around interior courtyards and uses a shared central boiler system for warmth throughout.
Architect Bruno Mathsson designed this building in 1956 and introduced Brunopane, a triple-glazed window unit that changed glass construction in Sweden. This innovation later influenced residential building standards across the country.
The building serves as a hub for glass art and workshops, keeping alive the region's glass-making tradition that stretches back centuries. Visitors watch artisans work with molten glass and can participate in demonstrations that show how this craft is still practiced today.
The site offers tours of glass-making processes, art exhibitions, and a restaurant with views of the workshop area. Visitors should allow time to watch demonstrations, and the building is easy to navigate since the spaces flow openly into one another.
The building was one of the first to use Brunopane windows at large scale, a technology that was groundbreaking at the time. This invention made it a testing ground for sustainable heating principles in modern design.
