★Industrialization of traditional wooden construction. We support the enhancement of added value for construction companies with stable factory production performance and the ability to achieve waterproofing and locking within a single day of framing. ★The fast construction speed and compatibility with ZEH (Net Zero Energy House) are due to stable factory production. ★In a nutshell, our large wooden panel processing service represents the "industrialization of traditional wooden construction." Traditional wooden home building is deeply rooted in Japan's climate and the lifestyle of its people. By leveraging the advantages of traditional wooden construction and implementing thorough pre-factory production, we address the issues that relied on the intuition and experience of craftsmen on-site. We support your home building with stable quality and reduced construction time. ★The large panels industrialized from traditional wooden construction do not require special techniques or skills. Framing, locking, and waterproofing can be completed in one day, significantly improving productivity. ★Building homes using large wooden panels is convenient and hassle-free. You can easily determine the number of walls (panels) and necessary materials needed to transform the floor plan into a three-dimensional structure, and then leave the rest to the factory. You only need to wait for delivery on-site. We can accommodate unique exterior designs, layouts, and even buildings other than residences. ★By enabling one-day framing, we have significantly reduced unnecessary exchanges and waste materials in on-site construction.
