Kosta Glashus (also called Bruno Mathsson's glass house) was built in 1955 by Kosta Glasbruk as housing for the mill's officials. The architect was the famous furniture maker Bruno Mathsson, who was inspired by both American and Japanese architecture. The hall, living room and kitchen have mosaic floors throughout, and the entire bathroom is also covered in mosaics. Each of the five townhouses has its own color theme. The fact that there was a refrigerator, bath, toilet and underfloor heating was not common at the time and made the houses extremely modern.
The house consists of five apartments, one of which is a viewing apartment. During the summer, the viewing apartment is open every day and other times on request
