Kyoei Steel, a leading Japanese company, recycles steel scrap using electric furnaces to produce structural steel. The new Yamaguchi office, themed “An Office Embraced in Recycled Steel,” expresses the transformation of scrap into steel through architecture. The exterior draws inspiration from stacked billets, while the interior utilizes locally produced angle steel and rebars as materials. Designs based on the “barcode pattern” and “QR code” extend from the entrance to office spaces, creating harmony of steel and light. The lighting design transforms these digital patterns into 3D, adding depth and movement, symbolizing Kyoei Steel’s identity and vision for the future.
