Urban Renewal in Beijing: Dinghao Electronics Building Transformed into High-End Office Hub by Nikken Sekkei

The Dinghao Electronics Building, once a bustling commercial hub in Beijing’s Zhongguancun district, has undergone a transformative upgrade led by renowned architecture firm Nikken Sekkei. This large-scale adaptive reuse project has reimagined the 200,000-square-meter complex into a state-of-the-art high-end office building, embracing sustainable practices and showcasing a new model for urban regeneration in China.

From Silicon Valley of China to Smart Office Complex

Originally constructed in two phases between 2003 and 2008, the Dinghao Building stood as a central fixture in Zhongguancun—often referred to as the "Silicon Valley of China". Surrounded by elite institutions such as Tsinghua University and Peking University, the area is home to numerous leading IT companies and startups. Strategically located at the gateway to Zhongguancun and directly linked to Subway Line 4 via two underground levels, the building once thrived as a retail and electronics marketplace. However, with evolving technology trends and dwindling foot traffic, the structure became crowded with small retail shops and was in urgent need of a visionary transformation.

Adaptive Reuse over Demolition: A Sustainable Urban Strategy

In a bold departure from conventional scrap-and-build urban renewal, Nikken Sekkei adopted an adaptive reuse strategy—preserving the existing structural frame while entirely renovating the facade and reprogramming the interior spaces. The project focused on converting the outdated commercial layout into a dynamic, future-ready office environment to meet the rising demand for premium workspaces in central Beijing.

This approach yielded extraordinary environmental and economic benefits:

• 63% reduction in embodied carbon emissions compared to new construction
• 62% lower construction costs
• 50% shorter construction timeline

This innovative model of urban revitalization aligns with China’s broader policy of reducing carbon footprints while enhancing the value of existing urban assets.

Reconfiguring Spatial Value: Light-Filled Atrium and Functional Layouts

A key architectural move was the rational reallocation of floor space. By carving a central atrium that spans from the ground floor to the top of the building, natural light now permeates the core spaces—enhancing interior quality and user experience. Although this reduced the overall floor area slightly, the reallocated volume was compensated by expanding the upper floors, which command higher rental value in the office market.

In total, approximately 4,000 square meters (7% of above-ground GFA) were reconfigured, optimizing the building for its new office function while minimizing cost and structural intervention.

Transit-Oriented Development: Reviving the Urban Fabric

Leveraging its deep experience in Transit-Oriented Development (TOD), Nikken Sekkei revitalized the building’s connection to the city. Previously, an underused, poorly lit underground corridor linked the subway station to the commercial core. The architects reactivated this circulation route, introducing vibrant retail and communal spaces along the corridor to foster urban vitality and strengthen the connection between public transport and commercial activity.

Innovation and Community: Building a New Urban Ecosystem

The renewed Dinghao Building is not just an office complex—it’s envisioned as a hub of innovation. By blending flexible office spaces with public zones for interaction and exhibition, the architecture promotes synergy among startups, researchers, and entrepreneurs. The project acts as a physical and social bridge between innovation, culture, and community, reinforcing Zhongguancun’s reputation as a global tech center.

A Contemporary Façade with Historic Memory

Visually, the building’s identity has been reborn through a complete exterior overhaul. Inspired by the concept of “inlaying,” the design utilizes a blend of materials and volumes that reflect the diverse talents and technologies of Zhongguancun. The previously flat, monolithic façade has been broken down into articulated volumes, echoing the building’s internal logic while creating a more human-scale presence in the cityscape.

The entire previous envelope was removed and replaced with a Low-E glass curtain wall, improving natural daylight and thermal performance. The design expresses functional clarity, with solid surfaces highlighting core areas and transparent zones opening up workspaces to the exterior. This intervention led to a 35% reduction in operational carbon emissions, significantly elevating the building’s environmental performance.
