Pengshui city planning

Masterplan and urban regeneration



The intervention covers an area of over 3,000 hectares, starting from a territorial analysis of the municipality. The project includes both the urban planning of new districts and a special report for the regeneration of the city center.



Area: 3.000 Ha. Location: Pengshui, China Client: Local government of Pengshui In collaboration with LKS Ingeniería S. Coop and GP&D


Pengshui is a city of about 100,000 people located in southwestern Chongqing Municipality. The city occupies a mountainous zone between the three valleys form by the junction of the Yangtze and Wujiang Rivers. Even though the area is not extremely industrialized, the city is experiencing an extraordinary increment of population driven by the improvement of infrastructures and the latest economic policies. It is expected a 200% population growth in the next ten years.

Since the origin of the city, its urban development has been strongly affected by the rugged topography. The shortage of flat land is the reason why the city has gone through an uncontrolled process of densification in the center and later has jumped into an urban sprawl of the nearby valleys, becoming a fragmented and polycentric structure made of five clearly differentiated neighborhoods.

These two factors, lack of space and absence of policies, have led to planning and infrastructure problems unusual in other Chinese cities affected by the same development process.

The intervention starts with a territorial analysis of the municipality to determine the economic factors driven the urban growth and the relationship between the capital and the adjacent towns.

The metropolitan is divided into several new areas marked for new development. The most important are Boajia, Changtan and Dianshui.

The masterplans of these neighborhoods are proposed considering the connection with the old city, the hierarchy of the mobility system, the land use and the density. The result is an urban planning model characteristic of a diverse city where residential typologies adapted to slope are commonly used.

On the contrary the intervention in the zone center is undertaken as a process of urban regeneration. The self-built housing process that has taken place on the slopes has resulted in high densified zones with problems related to transportation, environmental impact and lack of public facilities. The project starts with a deep study of the urban fabric to propose opening of new roads, insertion of public spaces and comprehensive land use optimization.

The developed studies propose an environmental renewal of the urban fabric by documenting and cataloguing the built structures, assigning of levels of protection in emblematic areas and improving the urban furniture, paving and building facades.

This strategic plan is also completed with other specific interventions for improving the image of the city such as  the treatment and regeneration of the riverbanks, (affected by seasonal changes in water level), or the proposal of certain public buildings in strategic areas to become driving forces in the regeneration process and be considered as identity elements for the city.
