NCN Supports Completion of Large-Scale Wooden MUJI Store in Seika

NCN's Innovative Role in MUJI Seika's Construction

The Tokyo-based company NCN Co., Ltd., known for its wooden architecture platform, has recently made notable contributions to the completion of the new large-scale wooden retail store, MUJI Seika, located in Seika Town, Kyoto. In collaboration with Ryohin Keikaku Co., Ltd., the company provided structural calculations, building environmental design, and high-quality construction materials for this ambitious project. NCN's support was bolstered by synergistic efforts from their group, particularly through Building Information Modeling (BIM) provided by KINOBIM. This collaboration laid a strong foundation from design to material supply, ensuring the project's success.

Emphasizing Sustainability in Design

NCN has previously assisted Ryohin Keikaku in achieving its medium-term management vision aimed at being an 'ESG Top Leader'. They supported the construction of the wooden MUJI stores in Karatsu and Hita in 2024. Now, with MUJI Seika, they have set a landmark in wooden architectural design, especially in areas demanding stringent fire safety measures. The structure is fully designed to comply with advanced standards while remaining a sustainable wooden building.

Generally, the construction industry has leaned toward steel and reinforced concrete for large structures in fire-prone areas. However, NCN's approach promotes wooden construction as a viable option by mitigating cost barriers and leveraging innovative design principles. Working closely with MUJI HOUSE, NCN has successfully constructed over 3,000 wood-based buildings since their collaboration began in 2003.

Features of the MUJI Seika Building

Utilizing the proprietary SE construction method, a unique wood-based structure that aligns with the latest Japanese building codes, NCN facilitated a spacious, open environment in the new store without compromising safety or aesthetics. This innovative approach allows for clear sightlines throughout the store, maximizing spaciousness without obtruding columns.

The MUJI Seika was specially planned as a 'fire-resisting building', integrating advanced fire-resistant technologies to delay combustion and provide customers with safe escape routes during emergencies. It incorporates 290 cubic meters of locally sourced timber, underscoring a commitment to regional resources and contributing to a carbon storage equivalent of 212 tons. Additionally, the building has achieved the 'ZEB' certification, indicating that its energy consumption is virtually zero.

Community and Global Impact

Beyond its commercial purpose, MUJI Seika is strategically designed to function as a safety hub during disasters, featuring solar power coupled with battery storage capabilities. This ensures the store can operate independently during power outages, providing essential services, such as phone charging stations, for community members in emergencies. Through collaborative agreements with local authorities, the facility aims to offer reliable support and services to the community in times of need.

Expert Comments on Sustainability

A representative from MUJI HOUSE highlighted that the wooden elements in the store create a warm and welcoming atmosphere, aligning perfectly with MUJI's core philosophy of 'natural beauty' and simplicity. Customers reportedly choose to spend more time in the store due to its inviting design, positively affecting sales.

Similarly, Masahiro Kizu from NCN pointed out that the growing emphasis on CSR and SDGs implies a necessity for businesses to actively reduce CO2 emissions through facility investments. He anticipates a continuous trend toward wooden structures in buildings and aims to leverage NCN's expertise to overcome inherent challenges faced in this sector.
