Your innovative approach to transforming recycled steel billets into architectural elements at the Embraced in Recycled Steel Office has garnered significant recognition - could you share the creative journey that led to this groundbreaking aesthetic decision?

The idea originated from observing Kyoei Steel’s recycled billets—solid, weighty, and full of narrative. I wanted to reinterpret these industrial forms not as raw materials but as architectural expressions of renewal. Through the stacking and layering of billet-inspired volumes, the building symbolizes the cyclical rebirth of steel. It transforms industrial matter into a spatial metaphor of sustainability, where strength and refinement coexist.

The integration of QR code-inspired vertical designs and lighting systems in the Embraced in Recycled Steel Office creates a unique visual narrative - how did this concept evolve during the design process, and what technical challenges did you overcome to achieve this striking effect?

The barcode and QR code motifs evolved from the idea of connecting the analog materiality of steel with the digital future of manufacturing. The vertical rhythm represents data flow and production traceability. Technically, integrating LEDs into these narrow vertical slots was challenging; we developed custom aluminum channels to achieve precise light diffusion without visible fixtures, transforming digital code into architectural light.

Given the extensive scale of the Embraced in Recycled Steel Office, spanning nearly 4,000 square meters, how did you ensure that the sustainable design principles and recycled steel elements maintained visual coherence throughout such a large space?

Consistency across the vast area was achieved through a modular rhythm derived from billet proportions. Every element—facade panels, ceiling grids, lighting strips—follows this proportional rule. By repeating and scaling this module, the design maintains harmony while adapting to each functional zone. The sustainable concept thus becomes not only material-based but also systemic, embedded in the architectural logic itself.

The stairwell design in the Embraced in Recycled Steel Office masterfully combines steel and light to communicate Kyoei Steel's technology - could you elaborate on how this architectural feature serves both as a functional element and a symbolic representation of the company's vision?

The stairwell serves as the building’s symbolic core. Here, recycled steel bars and billet-shaped LEDs intertwine vertically, representing Kyoei Steel’s philosophy of “steel connecting people.” The light travels along these rods like flowing energy, guiding users upward. Functionally, it ensures safety and openness; symbolically, it embodies the company’s technological elevation and collective growth.

Looking at the remarkable exterior facade of the Embraced in Recycled Steel Office, how did you develop the special coating techniques that create those textural variations symbolizing the recycling process?

We developed a multi-layer coating system combining zinc primer, black epoxy, and metallic silica particles. This method creates a nuanced surface that changes from matte gray to deep metallic tones depending on sunlight. It visually narrates the recycling process—the transformation of steel from raw to refined—turning the facade into a living skin that reflects both time and craftsmanship.

The Embraced in Recycled Steel Office showcases an innovative use of angle steel, flat bars, and deformed steel bars as finish materials - what inspired you to bring these typically hidden structural elements into the forefront of the architectural expression?

These components are usually hidden within structures, but here they take center stage. By exposing them, we wanted to reveal the unseen artistry of manufacturing. Each material retains its industrial texture—scratches, weld marks, oxidation—becoming a trace of human craftsmanship. The design redefines steel not as a cold material but as a carrier of memory and human touch.

In designing the Embraced in Recycled Steel Office, how did you balance the practical requirements of a corporate workspace with the artistic vision of creating an architectural statement about sustainability and material regeneration?

While meeting the practical demands of an office—efficiency, comfort, and workflow—we also sought to create an emotional narrative of sustainability. Spatial planning follows rational logic, while lighting and material choices evoke emotional resonance. This balance allows the workplace to become both a functional infrastructure and a symbolic statement of corporate values.

The lighting design in the Embraced in Recycled Steel Office, particularly the seamless LED fixtures shaped like billets, creates a unique atmosphere - could you share the thought process behind this distinctive interpretation of industrial elements?

The billet-shaped LEDs were conceived as architectural metaphors for steel rebirth. Their linear continuity mirrors the extrusion process of steel billets, while the seamless junctions eliminate visual interruption. Custom diffusers and heat-dissipating channels ensure durability and clarity. The light itself becomes a sculptural element—symbolizing both structure and illumination as one.

As the Embraced in Recycled Steel Office serves as both a functional workspace and a showcase for Kyoei Steel's commitment to sustainability, how did you ensure that the design would effectively communicate this dual purpose to visitors and employees alike?

The design allows visitors to “read” Kyoei Steel’s identity through space itself. From the recycled materials to the lighting choreography, every element tells a story of regeneration. For employees, the building becomes a daily reminder of their contribution to a sustainable cycle—transforming work into participation in a shared vision.

The successful execution of the Embraced in Recycled Steel Office has earned recognition through the A' Design Award - how do you envision this project influencing future architectural approaches to incorporating recycled materials in corporate spaces?

The A’ Design Award acknowledged not only the project’s aesthetic innovation but its ethical vision. It proves that industrial architecture can transcend its utilitarian nature to embody corporate philosophy and environmental responsibility. This recognition motivates us to keep exploring how recycled materials can narrate the beauty of transformation in future corporate architecture.
