Increasing numbers of architects are celebrating the strength, beauty, and sustainable properties of cross-laminated timber. Japanese architecture firm Junichi Kato & Associates shows off how the timber can be used as both a structural and finishing material in the Santo CLT Office. Built in Japan’s Shiga Prefecture, this nearly 140-square-meter office building houses warm and welcoming workspaces with arched openings.

Inspired by the climbing kiln in Shigaraki, a town famous for ceramics, Junichi Kato & Associates introduced an arch-shaped continuous frame into the building structure. A raised wooden terrace wraps around two sides of the building and is partly shaded by the roof overhang. The walls and floors are constructed from cross-laminated timber, while foam insulation and low-e glass improve energy efficiency.

The office is entered from the west and visitors are immediately greeted with an exhibition space, reception desk, and a small informal meeting area. A wall divides the entrance area from the large working space in the center of the building. The night-duty room, shower, and toilet are located in the rear. Large windows fill the office with natural light which, coupled with the ample use of wood, gives the office its cozy and welcoming character.
