KarlsonHus looks at the big picture. We are the only Swedish manufacturers to offer a complete low energy concept, which doesn’t only look at the use of energy, but also renewable and ecological materials. This work has been recently rewarded. Our houses are carbon dioxide negative and so energy efficient that they exceed the requirements set out by the Swedish National Board of Housing, Buildings and Planning (Boverket). We have accepted the challenge of global warming and managed to unite our environmental aims with quality of life, healthy living and top class design. Sweden’s most beautiful houses have become Sweden’s most climate smart houses.
