The home connector is a hardware that allows for strong, beautiful, and easy joining of wood, commonly referred to as GIR. It can be used not only for general wood joints and connections but also as a joining hardware for structural frameworks such as frame structures.

The upper pergola, symbolizing the forest, is constructed using 286 logs sourced from Kumamoto, Oita, Miyazaki, Shimane, Nara, Osaka, Wakayama, Tottori, and Tokushima, each tagged for traceability. The triangular lattice and beams, featuring traditional decorative patterns, create a play of light and shadow that envelops visitors like dappled sunlight. The joint for the GIR (Glue-in Rod: Home Connector), which requires structural strength at the top of the log columns, is designed to allow for a gap for vertical cutting of the materials. The lower part of the columns is not structurally fastened, allowing for easy disassembly. After the expo, it will be relocated to Uzbekistan. 【Project Overview】 ■Structure: Wooden and partially steel structure ■Floors: 2 stories ■Total floor area: 640.43 m² ■Location: Osaka Prefecture (Expo site) ■Concept & Design: ATELIER BRÜCKNER ■Design Supervision: Tokuoka Design *For more details, please refer to the related links or feel free to contact us.

Due to the structure of the indeterminate ramen, which is constantly subjected to significant bending stress at the joints, the home connector method using GIR (glued-in rod) was adopted to meet the requirement of minimizing the exposure of hardware as much as possible.

The design blends into the surrounding landscape and creates an open and spacious roof space. The roof is finished entirely in wood, and by using wooden materials for the interior as well, the warmth of nature is spread throughout the entire space. To construct the large space while utilizing the properties of the materials, a reciprocal structure is adopted. This is a structural method where multiple beams support each other to ensure stability. Furthermore, at the joints, GIR (Glue-In-Rod: Home Connector) joints are used, achieving both aesthetic appeal and structural performance without exposing hardware. 【Project Overview】 ■ Structure: Wooden + Steel Frame ■ Number of Floors: Single Story ■ Total Floor Area: 293.71m² ■ Location: Chuo Ward, Fukuoka City, Fukuoka Prefecture ■ Design: Atelier Sankaku Scale *For more details, please refer to the related links or feel free to contact us.

In heavy snowfall areas, despite being a wooden structure, a light roof expression and a large space for restaurants and shops were achieved by adopting "keel beams" and "lattice beams," which are used in boat hull structures, for the roof framing. By rigidly connecting the joints with GIR (Glue-In-Rod: Home Connector), structural challenges were resolved. Additionally, a curved section was incorporated into the lattice ceiling, adding a soft accent to the space. 【Project Overview】 ■ Structure: Wooden ■ Number of Floors: Single-story ■ Total Floor Area: 393.34m2 ■ Location: Iwamizawa City, Hokkaido ■ Design: NTT Facilities, Inc. *For more details, please refer to the related links or feel free to contact us.

The main sales area is covered by a large roof made of wood, stacked in two layers, resembling overlapping branches and leaves. Supporting this large roof are the diagonal columns "Kibana" made of cedar logs, which expand in all directions like naturally grown trunks and branches. By using GIR (Glue-in Rod: Home Connector) joints at the intersection points, the stability of the shape and structural performance is ensured without the use of metal fittings like rings, achieving a light and delicate design. GIR is also used for the connections at the tops and bases of the columns. 【Project Overview】 ■ Structure: Wooden ■ Number of Floors: Single-story ■ Total Floor Area: 863.47m2 ■ Location: Miyoshi City, Hiroshima Prefecture ■ Design: NAF Architect & Design *For more details, please refer to the related links or feel free to contact us.
