If it's a healthy home or a custom home, it's a natural house. What we can do for the children of the future.
We have been researching for many years whether it is possible to build houses without using harmful chemicals such as synthetic adhesives and chemical building materials. By carefully selecting natural materials for building materials and striving to minimize the use of chemicals, we have achieved the ultimate in additive-free construction, leading to the birth of "additive-free houses." We believe that homes should coexist with nature, and we aim to build houses that anyone can live in comfortably and safely for 100 years. 【Business Activities】 ○ Development and manufacturing of building materials such as wall materials, flooring, roofing, and insulation made from natural materials for "additive-free houses." ○ Sale of building materials and recruitment of agents through the "additive-free house agency system." *For more details or to request a catalog, please contact us. *We are currently recruiting agents nationwide!
