2m26 revives century-old kyoto annex with cypress structure and rammed earth flooring

2m26 renovates annex for their office space in kyoto

Architecture and construction studio 2m26 completes the transformation of an annex into an atelier and office, setting the groundwork for the renovation of the main folk house on site. Nestled in Keihoku, a mountainous region north of Kyoto, the project preserves the century-old wooden structure while integrating traditional Japanese craftsmanship and locally sourced materials.

2m26 retains as much of the original handcrafted timber frame as possible, repairing damaged elements using traditional Japanese carpentry techniques. Complementing the existing framework, the studio introduces a cypress structure fitted with handcrafted sliding doors and windows. The annex embraces passive climate control, with a rammed earth floor—made from a mix of clay, sand, and lime—allowing the space to breathe in Kyoto’s humid summers.

handcrafted elements shape the identity of the atelier

Kyoto-based studio 2m26 shelters the outdoor space and firewood storage under a cedar bark roof, constructed using a time-honored process where the bark is hand-stripped from logs in summer, dried until autumn, and layered onto the rafters in seven nailed tiers. Inside, a long tool storage unit reinforces the back of the atelier, while two box stairs—reminiscent of traditional Machiya architecture—lead to the tatami-covered second floor, which serves as an office space.

Handmade wooden windows designed and built by 2m26 frame views of the surrounding landscape. Hinoki sliding doors seamlessly connect the interior with the outdoor workspace, emphasizing the studio’s commitment to natural materials and craftsmanship. A ceramic-supported copper lighting system was added post-completion, ensuring easy maintenance, while a wood-burning stove provides warmth and comfort throughout the working and living areas.
