Our company is engaged in research and development of diverse technologies for utilizing wood effectively. In the development and implementation of DLT (Dowel Laminated Timber), it can be manufactured even with small-scale facilities, making it suitable for production in small and medium-sized sawmills. Additionally, due to its low environmental impact during manufacturing and disposal, it is expected to be a new wood-based material. Furthermore, in collaboration with Archiloid Co., Ltd., we are developing a sales system for our housing using their automated design technology.

"So-Cal House" is a wooden residence that is based on the style of imported homes we have handled in North America for many years, made more stylish to suit Japanese living. We propose structural connection hardware for joints such as beams, columns, and foundations based on the reliable two-by-four construction method. Both construction methods distribute external forces acting on the building through points and surfaces, helping to mitigate deformation and twisting caused by major earthquakes. Additionally, by using a hardware method that minimizes processing involving cross-sectional defects in beams and columns, we ensure seismic resistance. 【Structure and Performance】 ■ Reliable structural body and seismic strength ■ Choice between "two-by-four construction" and "frame construction" ■ Hardware method reinforced with highly seismic-resistant connection hardware ■ Standard compliance with "long-term excellent housing" specifications for peace of mind ■ Durable and long-lasting, ensuring maintenance and durability performance *For more details, please refer to the PDF materials or feel free to contact us.

The "Wood Education House" proposed by our company utilizes the power of wood to create a living space where residents can live healthily and comfortably. We adopt a high-strength six-sided structure and a robust flat foundation method. By using structural components precisely processed in our own factory, we achieve a high level of peace of mind. Additionally, since the lifespan of plumbing for water supply and drainage is shorter compared to the structural framework, it is important to consider ease of maintenance, such as replacement. By using a header piping method that is not directly embedded in concrete, we ensure that inspections and repairs can be easily carried out. 【Structure and Performance】 ■ Reliable structural framework and seismic strength ■ Hybrid structure that combines the advantages of "frame" and "plane" ■ Reinforced with highly seismic-resistant connection hardware ■ Standard compliance with the reliable "Long-term Excellent Housing" specifications ■ Durable and long-lasting, with reliable maintenance and durability performance *For more details, please refer to the PDF materials or feel free to contact us.
