Interview about Embraced in Recycled Steel Office, winner of the A' Architectural Lighting Design Award 2025
Seamlessly blending innovation and sustainability, this office redefines the relationship between architecture and recycled steel. The façade, inspired by stacked billets, expresses material regeneration, while the interior integrates the company's own steel products with precision and elegance. Designed to embody Kyoei Steel’s vision, the space fosters creativity, collaboration, and efficiency, reducing environmental impact while reinforcing the company’s expertise, technological advancements, and unwavering commitment to sustainability and responsible manufacturing.

View Design DetailsThe billet-shaped LED fixtures express the transformation of recycled steel into new architectural value. Each linear luminaire symbolizes the rebirth of steel billets, representing Kyoei Steel’s philosophy of circulation and sustainability. By using energy-efficient LEDs and recycled steel components, we turned industrial materials into a poetic expression of light—bridging production and design in a sustainable narrative.
The barcode and QR code motifs visualize Kyoei Steel’s evolution from analog industry to digital innovation. These patterns metaphorically encode the company’s identity, linking material authenticity with information technology. The rhythmic black-and-white lighting composition embodies data flow and production rhythm, transforming industrial heritage into a language of digital modernity.
Maintaining the raw expression of steel while integrating sophisticated lighting required precision. We avoided decorative finishes, instead embedding linear luminaires into structural elements. Each fixture was designed to reveal the steel’s texture, oxidation tone, and depth, ensuring that technology amplifies, not hides, material honesty. This balance was achieved through meticulous mockups and reflectivity studies.
We designed the lighting to act as a continuum of the daylight entering through vertical slits. During the day, sunlight accentuates the metallic reflections; at night, embedded LEDs extend this rhythm into an artificial glow. The two light sources merge to create an ever-changing spatial atmosphere that mirrors the passage of time and the lifecycle of steel.
The project spans various functional zones—office, gallery, and production spaces—yet all are unified through a consistent linear motif. We applied a modular grid system based on billet proportions, ensuring visual harmony while allowing flexibility. The lighting intensity and color temperature subtly shift according to function, maintaining continuity without monotony.
Recycled steel was treated as a reflective medium rather than a mere structure. By precisely controlling light angles and distances, we revealed its layered surface tones—from cold matte gray to warm highlights. This transformation turns an industrial byproduct into an elegant architectural element, giving new dignity to recycled materials.
Our research focused on how light interacts with micro-textures of recycled steel. We discovered that diffuse reflection enhances both depth and warmth, allowing lower light levels with higher perceived brightness. This insight redefined our approach to sustainable lighting—achieving visual richness with reduced energy use.
The alternating rhythm of steel louvers and vertical lighting leads visitors intuitively through the space. The design simulates motion—light guiding flow, steel providing pause. This sequence creates a sensory navigation experience that reflects the continuous cycle of steel production and enhances both spatial legibility and workplace vitality.
This project demonstrates that sustainability can be expressed emotionally, not just technically. By fusing recycled materials with digital aesthetics, it suggests a new corporate architectural language—where light and material co-author the story of regeneration. I believe this approach will inspire future workplaces to embody circular values in expressive ways.
I believe the jury recognized the project’s ability to merge industrial authenticity with architectural poetry. The lighting transformed recycled steel into a medium of expression, not simply a function. Its spatial rhythm, sustainable message, and visual innovation collectively conveyed how architecture can narrate corporate philosophy through light.
