In Yukuhashi City, Fukuoka Prefecture, There is a complex facility centered on a library called Librio Yukuhashi. The project had a role as a catalyst to improve convenience for local residents and bring prosperity to the downtown area. It demanded a complex facility with support functions for civil activities and child-rearing, in addition to a library, which is expected to attract visitors.So, we planned to create an appropriate building that stands on the foundations of the history of the place named Yukuhashi connecting the two areas, while including contrasting characteristics, such as symbolic value and locality, as well as vitality and calm.

The city of Yukuhashi
Located 25 kilometers south-southeast of Kitakyushu, the city of Yukuhashi, with a population of 70,000 people, is a central city of the Keichiku region, Fukuoka Prefecture. In recent years, the city has become a satellite town for commuters to Kitakyushu. The city was named “Yukuhashi” by combining two Chinese characters each derived from the villages Gyoji and Ohashi that the municipal authorities merged into a city. The construction site of Librio Yukuhashi is located on the right bank of the Nagao-gawa River, which runs on the boundary between the former Gyoji and Ohashi villages. The two bank areas form a townscape, while leaving behind the former zoning of the villages.

During the Edo Period (1603-1868), the surrounding area of the site was a post town of the Nakatsu Kaido road. Nakatsu Kaido used to connect the castle towns of Kokura and Nakatsu as a major road in the northern part of Kyushu, and it went by the construction site. With advanced water transportation along the Nagao-gawa River, which runs in front of the site, the town also supported the castle town as the biggest rice production center within the Kokura Domain.After the Meiji Era (1868-1912), the former 130 Bank Yukuhashi Branch (present-day Yukuhashi Red Brick Building or Akarengakan) was built in front of the construction site. Believed to have been supervised by renowned Japanese architect Kingo Tatsuno, the Akarengakan is an important piece of architecture, the symbol of the economic power of the Gyoji and Ohashi areas in those days.

Two parts in a twisted arrangement
We designed the building with a “twisted” structure so that the upper part does not sit squarely on top of the lower part, and so that each part dovetails with the townscape of the former villages of Gyoji and Ohashi, respectively.The various functions are zoned within the building, with its lower floors the busiest and it getting progressively quieter as one moves upward. The lower space facing the Yukuhashi Red Brick Building is designed to welcome local people’s activities and bring new energy to the city, while respecting the history of the region. The upper space, with views of Nagao-gawa River and the surrounding mountains, is designed as a peaceful environment with carrels and space for learning.

The interior space is designed in a methodical way while expressing the structure of each part. For the achromatic interior and its bare materials, we introduced the glitter of the Nagao-gawa River as a pattern motif of the flooring and decorated the space around the elevator with accent colors. While arranging the different functions on the floors of the twisted upper and lower parts, we made the space continuous by unifying the interior materials and colors.

Architecture that weaves a history
A building with a twisted design stands in the center of a city. Although the silhouette may elicit a feeling of otherness, it is spatially continuous with the surrounding residential area, depending on the angle from which it is viewed.
While the twisted framework is designed to correspond to the location and its history, it generously encloses the required functions. The framework will survive no matter how the functions may change in line with the times.

The upper part has a steel-framed structure that enables the cubic volume to be lighter and the extended end larger. The lower part has a steel-reinforced concrete structure that transfers the stress from the steel-framed upper part. Thus, we achieved a good balance between the twisted design and creating an open space, while also satisfying economic efficiency and quake resistance.

Something that is not possible anywhere else
We believe that it is important to build public architecture that you could not create anywhere else, especially in the case of a local region.We expect that the building will weave new stories in the historical context of the location.
