Back in mid-2023, ID&E Holdings (Integrated Design & Engineering) was established through the reorganization of Nippon Koei. This strategic transformation was undertaken to enhance the flexibility and autonomy of each company, enabling them to respond swiftly and effectively to the evolving market landscape and emerging demands.
As part of our long-term management vision, our business group is committed to driving sustainable growth not only in the consulting and energy sectors but also in Urban & Spatial Development—a vital area shaping the cities of tomorrow.
Guided by the concept of “Working Together Toward a Future Without Boundaries,” we embrace Cross-Border Collaboration as the core of our approach. Through this vision, we strive to deliver world-class solutions and services in Architecture and Urban Development across Indonesia.
Under the umbrella of ID&E Holdings, Nippon Koei Consulting (NK), Nippon Koei Urban Space (NKUrban), and BDP stand as the group’s largest companies in the Architecture and Urban Development sector, combining deep expertise with innovative thinking. To further strengthen our presence and operational capacity in Indonesia, PT. Indokoei International (IKI)—a subsidiary of NK—also brings extensive experience and strong familiarity with the local market in consulting engineering and area development. The presence of Kisho Kurokawa Architect & Associates Co., Ltd., as one of the architectural companies in ID&E, brings a strong legacy of the Metabolism and Symbiosis philosophy. These timeless principles lay a solid foundation for developing sustainable, adaptive, and harmonious architectural and urban design solutions.
Together, we are committed to shaping vibrant, resilient, and sustainable cities—bridging ideas, technologies, and expertise across borders.
URBAN GROWTH COMES WITH COMPLEX CHALLENGES
Indonesia’s rapid urbanization brings both opportunities and challenges. From unplanned city expansion and traffic congestion to limited public spaces and environmental degradation, many urban areas struggle to balance development, functionality, and sustainability.
Architectural and urban development projects often face difficulties in integrating technical, social, regulatory, and environmental dimensions. These challenges demand more than just design; they require a holistic, multidisciplinary approach — where engineering precision meets visionary design thinking.
