A Model for Sustainable Office Transformation: Completion of the Dojima Kanden Building Renovation by Kanden Realty & Development and SEKISUI CHEMICAL
The large-scale renovation of the Dojima Kanden Building, the Osaka Head Office of SEKISUI CHEMICAL, has officially been completed, marking a major milestone in the evolution of urban office spaces with sustainability, ESG (Environmental, Social, and Governance) principles, and the United Nations’ Sustainable Development Goals (SDGs) at its core.
Located in the heart of Osaka, the Dojima Kanden Building has undergone a comprehensive transformation aimed at redefining the modern office environment. Following the renovation, the building has been reborn as a state-of-the-art facility that reflects both environmental responsibility and social progress. The project focused not only on reducing environmental impact and energy consumption but also on enhancing workplace comfort and job satisfaction. The result is a forward-looking office that allows employees to thrive while also contributing to the realization of a sustainable society.
This ambitious initiative was driven by the aligned visions of two companies: Kanden Realty & Development and SEKISUI CHEMICAL. Both organizations are firmly committed to sustainable development and environmental stewardship. The renovation embodies Kanden Realty & Development’s management philosophy of “realizing a sustainable future through the creation of reliable and comfortable community infrastructure,” while also bringing to life SEKISUI CHEMICAL’s long-term corporate vision of “Innovation for the Earth”—a vision rooted in the company’s mission to support the foundation of life and provide peace of mind for the future.
A Sustainable Transformation with ESG and SDG Consciousness
At the heart of the renovation project was the aspiration to create a building that not only meets but exceeds the standards of ESG and the SDGs. Rather than demolishing the existing structure and starting anew, the decision was made to preserve and upgrade the existing building—a clear example of maximizing the use of existing stock. This approach not only minimized construction waste and resource consumption, but also kept the building’s tenants in place throughout the renovation, avoiding business disruptions and supporting the local economy.
Such a method presents a model for other companies to emulate: instead of contributing to the cycle of demolition and reconstruction, buildings can be reimagined and revitalized with sustainability in mind. The project demonstrates how aging infrastructure can be transformed into high-performing, environmentally conscious spaces through thoughtful design and strategic planning.
Throughout the renovation, the design and construction teams implemented numerous environmentally friendly technologies and building features. These include energy-efficient HVAC systems, high-performance insulation and windows, LED lighting, and water-saving fixtures. The building also incorporates renewable energy sources and advanced monitoring systems that track energy use, helping to ensure continued energy efficiency over time.
This large-scale renovation serves as a benchmark for ESG-conscious redevelopment within the Japanese real estate industry, and a blueprint for how older office buildings can be retrofitted into modern, sustainable workplaces that are aligned with global standards for environmental and social responsibility.
A Workplace That Supports Job Satisfaction and Employee Well-Being
While environmental considerations were central to the project, equal emphasis was placed on the social aspects of sustainability—particularly, the creation of a workplace that fosters employee well-being, inclusivity, and long-term engagement. The Dojima Kanden Building now offers a working environment that is not only physically comfortable but also psychologically enriching, allowing each individual to feel empowered and motivated in their roles.
In pursuit of this goal, the renovated building includes enhanced common areas, breakout spaces for collaboration, quiet zones for focused work, and wellness-oriented amenities. Thoughtful attention was paid to indoor air quality, lighting conditions, noise levels, and ergonomic design—all of which contribute to a more supportive work environment.
These efforts align with SEKISUI CHEMICAL Group’s corporate commitment to building a workplace where ease of work and job satisfaction are in balance. The company has set its sights on creating an organization where employees with diverse backgrounds and skill sets can thrive, contributing to both the company’s success and the betterment of society.
The Group believes that fostering such an inclusive and engaging workplace is essential to realizing its broader vision of becoming an “excellent and vibrant company.” Central to this vision is the promotion of employee well-being and the belief that a happy, healthy workforce is the foundation for innovation, resilience, and long-term value creation.
Leading the Charge Toward a Zero-Carbon Real Estate Industry
With the successful completion of the Dojima Kanden Building renovation, Kanden Realty & Development has taken a significant step toward its goal of becoming a “leading zero-carbon company in the real estate industry.” By upgrading aging buildings rather than demolishing them, the company is reducing the carbon footprint associated with construction while extending the usable life of existing properties.
Kanden Realty & Development is actively engaged in efforts to decarbonize the real estate sector. The company sees the Dojima Kanden Building as a model case of what can be achieved through sustainable renovation, and plans to replicate this approach in other buildings across its portfolio. These projects are guided by a long-term commitment to environmental responsibility, social value creation, and sound corporate governance.
Moving forward, the company will continue to promote zero-carbon building practices, prioritize resource efficiency, and invest in community-friendly infrastructure that supports both people and the planet.
SEKISUI CHEMICAL’s Ongoing Sustainability Commitment
SEKISUI CHEMICAL Group is likewise advancing its sustainability agenda with a particular focus on circular economy principles. Beyond creating an ideal workplace, the company is also committed to reducing waste and promoting resource recycling throughout its operations.
As part of its corporate responsibility efforts, SEKISUI CHEMICAL is exploring new materials and technologies that enable recycling, reduce emissions, and support a low-carbon society. The company’s commitment to sustainability is holistic—spanning its products, processes, supply chains, and, as demonstrated by the Dojima Kanden Building, its physical offices as well.
By integrating sustainability into every facet of its business, SEKISUI CHEMICAL aims to not only contribute to the SDGs but also set a global example of how corporations can drive meaningful environmental and social progress.
