The intervention follows 4 main principles aimed at ensuring the coherence of the city, functional, resilient, and deeply rooted in its time: 

- The preservation and cultural enhancement of the industrial heritage.

- The valorization of the landscape and the creation of new green spaces, including a large garden-park that runs throughout the district and preserves the existing trees. 

- Optimization and development of water resources, including the development of the banks of the Qin River, which runs through the site. 

- The development of mixed, connected and flexible programs, based on the concept of Hôtel Métropole developed by DPA. 

A "toolbox" of ideas defines the district's shape and density. The movements of this silhouette are linked to the urban and geographical environment, marking with high points the doors of the district, or accompanying with low points the surrounding streets. Each of the elements that make up the new district protects and enhances the industrial heritage of the site, while allowing the reception of new programs and circulation axes. Finally, through the combination of various densities, the project aims for a harmonious balance between city and nature.

This approach, through a "toolbox" strategy, confirms the need to move away from the rigid urban planning of the 20th century, where functions and programmes were carefully planned and unable to absorb change. The proposed Masterplan wishes to provide an impulse for the future development of Handan. An outstanding example of 20th century industrial urban planning, Hangang district will hopefully be an example of resilient urban planning.
