History of our ecological building kit

In 2005 construction engineer and entrepreneur Bo Mansson founded Bosum AB. After 30 years in the construction industry Mansson had started to develop a new building system that revolved around three central perspectives - indoor climate, soundproofing and environment. In the following years Mansson continued to developed his building system where massive wooden blocks proved to be an excellent building material to work with. It would not be long until a new construction system was developed where the method and material generated an adaptable indoor climate, soundproofing benefits and besides it  consisted entirely of only one organic material, pine.

The building system has an approval by SP Technical Research Institute. Thus, it is approved in the Board's regulations and general guidelines on the application of European construction standards (EKS).

Over the years, the product and the company has developed. Bosum AB underwent in 2015 a reorganization and the subsidiary Bosum Building System AB was formed. The subsidiary took over the sales activities with kits made of solid wood and continued to drive the business forward. Today, the subsidiary of people holds a genuine interest in housing construction where the ecological and environmental aspects play an important and central role and has come further developed. We at Bosum Building System are extremely proud of our product and the benefits that it generates, both for our customers and for our environment.
