Wood One Co., Ltd. (Head Office: Hatsukaichi City, Hiroshima Prefecture, President: Yutaka Nakamoto) will add a new lineup to its "DOORETUS" series for creating spaces that pursue beauty down to the details. In addition to the "Substrate Frame" with invisible frames, for which pre-orders began in April, the company will begin accepting orders for the new "Overlay Frame (Storage Fixtures)" from July 1, 2026 (Wednesday). This product not only meets the design needs of architects and designers who want to "reduce lines as much as possible," but also streamlines construction work. Furthermore, it incorporates features that allow residents to use their space more broadly and beautifully, proposing a clean space creation that offers benefits to all three parties. Launch of Wood One DOORETUS Series Interior Door "Overlay Frame (Storage Fixtures)" Background of Development In recent years, in addition to rising construction costs due to soaring prices of building materials and labor costs, housing sizes are becoming smaller (more compact) in line with improvements in housing performance, such as the mandatory compliance with energy-saving standards (2025) and the ZEH standard obligation target (2030). On the other hand, architects and designers from architectural firms and the like tend to prefer "reducing lines as much as possible" and dislike unnecessary lines and steps. They design spaces to look cleaner and larger by making door heights reach the ceiling or making frames inconspicuous. However, achieving these through conventional on-site construction requires high skills from carpenters and a lot of construction time, posing a challenge for installation companies. Against this backdrop, this year's DOORETUS was developed with the concept of "noiseless spaces that create 'white space,'" featuring noiseless doors and storage fixtures with invisible frames.
