Appreciations towards Shanghai PTA for providing the following description:


Urban Renewal is to revitalize one city block which no longer meets the needs of modern urban social life. For cities in China, especially the first-tier cities, the concept of urban renewal becomes more and more important. It helps cities reshape vitality, utilize the existing resources and improve the quality of entertainment and cultural life for people.

Shanghai Jing’ an Qicaili is a renovation project for the current building (Jing’ an China Mall) designed by PLA+Partners under Shanghai PTA for Greenland Group. The project is within Caojiadu Business District, located in the junction area of 3 districts (Jing’ an, Changning, and Putuo), highly accessible to several core commercial blocks.

The existing building (Jing’ an China Mall) had been left undeveloped after its construction for a number of reasons. Since the initiation of the project, a series of analyses and measuring have been carried out; meanwhile, a mutual decision has been made based on our analysis and the suggestions collected from the client that a curtain wall system is adopted.

Our main principle for this renovation project is to maintain the basic form of the original building, preserve the initial form and retain the exterior part on the 2nd to 4th levels. Moreover, despite dissecting the existing facades, we endeavor to keep its original structure intact. The entirety of the expression of the project’s innovations and ideas go on the additional layers.

The most valuable forming relations of the existing building is outlined with rough stroke, then the most of the building is overlaid with uniform, tasteful and unadulterated perforated metal panels under consideration of the natural lighting and ventilation requirements. Beyond the main entrance ahead the crossroad, a series of enameled tempered glass are designed to complete the hollow-solid materials comparison.

Those perforated metal panels on the cladding façade have been divided into 6 types with different horizontal heights. With 6 groups of metal panels meshed, we create a unique cladding design with a beautiful eye-catching “wave” façade at the day time, as well as a night-time illumination.

We also take account of natural lighting when standing inside of the building. By retaining all the current windows, we gave a visually crystallization to all the windows in virtual design process, and designed larger-diameter panels in those positions need more light penetration-where the windows are.

During the process of urbanization, buildings with particular antiquated designing styles have fallen out of favors of contemporary aesthetics and practical demands. Therefore the redevelopment and redesigning of such buildings, and revitalizations have been a focal point in the industry down the stretch.
