To build with cubes we tried to combine a light material like EPS with steel and wood. In this way it easier to build light, strong and insolated houses. When you build in Zunderdorp/ The Netherlands like we do, it has it’s advantages. Of course in other places on this planet other materials might be in favor. It wouldt be a challenge to combine all these materials in one system. Do you have ideas or questions, please send them to our forum page.
