Award-Winning CLT Architecture in Urban Settings

In a recent recognition, the Setagaya Kamimura Cafe has garnered the Excellence Award at the CLT OF THE YEAR 2025 for its pioneering approach to CLT (Cross Laminated Timber) construction. Managed by Life Design Kabaya Co., Ltd., the project was designed and executed by A.D. and C Co., Ltd., based in Setagaya, Tokyo. The ceremony highlighted innovative practices that challenge the conventional interpretation of urban construction, especially in small areas.

The Project Overview

The winning cafe, constructed under the LC-gate method, has a compact yet functional area measuring just 61.69m² (approximately 18.6 tsubo). This design adapts to the limitations of urban plots, featuring a width of just 5.1 meters. Intended as a client-facing structure, the cafe is a prime example of how to maximize space and utility in densely populated areas, transforming restrictions into opportunities for creativity and functionality.

The LC-gate method innovatively restructures how CLT buildings can be designed, particularly in urban environments where space is at a premium. It emphasizes both efficiency and sustainability, serving as a model for future urban developments.

Efficient Construction Techniques

One of the significant highlights of this cafe's construction was its remarkable efficiency. The project achieved a construction time of just 7 days, an impressive feat given the complexities typically associated with urban building projects. Moreover, it utilized pre-finished wall panels, minimizing the need for scaffolding and thereby reducing overall construction waste and disruption to the vicinity.

The emphasis was placed not merely on the amount of CLT used but rather on the effective application of its properties in creating a building suitable for urban living. By integrating various innovative techniques, the team successfully established a viable and efficient construction method that respects both the integrity of the materials and the surrounding environment.

Impact on Japanese Forestry and Carbon Neutrality

The achievement marks a pivotal moment for Life Design Kabaya and the Japan CLT Technology Research Institute, as this is their first accolade at the CLT OF THE YEAR awards. Their commitment to enhancing the use of domestically-sourced wood contributes significantly to revitalizing Japanese forestry practices, aligning with national goals towards achieving a carbon-neutral society. Supporting such sustainable construction methods reinforces the broader movement towards responsible environmental stewardship and social responsibility in architecture.
