About Embraced in Recycled Steel कार्यालय आन्तरिक डिजाइन

"रिसाइकल गरिएको स्टिलमा आबद्ध" (Embraced in Recycled Steel) क्योएई स्टिल (Kyoei Steel) द्वारा आपूर्ति गरिएको पुनर्चक्रित स्टिलले निर्मित कार्यालयको आन्तरिक डिजाइन हो। सामग्रीको बल र बनावटलाई जोड दिन एङ्गल स्टिल, रिबार र फ्ल्याट बारहरूलाई खुला रूपमा देखिने गरी राखिएको छ। सामान्यतया लुकाइने संरचनात्मक तत्वहरू यहाँ सौन्दर्यात्मक केन्द्रबिन्दु बनेका छन्। बारकोड र क्यूआर कोडका आकृतिहरू भित्ताका फिनिस र भर्‍याङका रेलिङहरूमा फैलिएका छन्, जसले यस स्थानलाई कम्पनीको पहिचानसँग जोड्छ। स्टिलका सिलिङ लुभरहरूमा अविच्छिन्न रेखीय एलईडी प्रकाश व्यवस्था राखिएको छ, जसले ती आकृतिहरूलाई उजागर गर्छ। यो आन्तरिक डिजाइनले समकालीन कार्यस्थलमा पुनःप्रयोग गरिएका सामग्रीहरूको सम्भावनालाई प्रदर्शन गर्छ।

Production Technology
The office interior features angle steel, rebars, and flat bars as exposed materials, emphasizing their structural and aesthetic qualities. Barcode motifs, derived from Kyoei Steel’s website, are embedded in wall finishes and stair railings, linking physical space to digital branding. The ceiling’s steel louvers incorporate billet-shaped seamless LED lighting, reinforcing a cohesive design language that blends recycled materials with innovative illumination.
Design Challenge
The primary challenge was redefining recycled steel’s role in architecture beyond its conventional industrial use. Integrating angle steel, rebars, and flat bars as visible elements required precise detailing and innovative finishing techniques. Additionally, balancing material authenticity with a refined aesthetic posed a design challenge. Regulatory constraints, production limitations, and ensuring harmony between raw steel textures and digital motifs, such as barcode patterns, demanded extensive prototyping and iterative design development.
Research
Type of Research: Applied Design Research
Objective: To explore the aesthetic and functional integration of recycled steel in office interiors.
Methodology: Material experimentation, spatial simulations, and lighting analysis.
Data Collection: Prototype testing and digital modeling.
Participants: Architects, engineers, and Kyoei Steel stakeholders.
Results & Insights: The research highlighted the potential of exposed steel as a design element, demonstrating its structural beauty and reinforcing corporate identity. The study advanced sustainable interior design, influencing material reuse practices in industrial architecture.
Inspiration
The design embodies the lifecycle of steel recycling while visually integrating Kyoei Steel’s digital identity. Barcode and QR code patterns, inspired by the company’s website, appear throughout the space, symbolizing the transformation of raw materials into structured design. By exposing and celebrating recycled steel, the project creates a unique spatial narrative, merging industrial heritage with a contemporary digital aesthetic.
Project Duration
The project commenced in early 2022 in Yamaguchi, Japan, with design and planning phases focused on integrating Kyoei Steel’s identity into the architecture. Construction began in mid-2023, aiming to unify office functions while enhancing operational efficiency and employee engagement. The office was completed in early 2024, creating a sustainable workspace that embodies the company’s commitment to steel recycling and innovation.
Operation Flow
The office interior integrates barcode and QR code motifs, linking the space to Kyoei Steel’s corporate identity. These patterns, expressed in wall treatments and stairwell designs, create an interactive experience, guiding movement through the space. The ceiling’s steel louvers diffuse light while reinforcing the visual continuity of barcode-inspired elements. This design transforms an industrial material narrative into a contemporary, high-tech environment.
