Chengdu "Excellence · Dianjiangtai 79" Urban Renewal Complex

Meng Fanhao, co-founder and chief architect of line+, was commissioned to serve as the chief designer and overall architect for the core urban renewal project in Chengdu's old city center, the "Dianjiangtai No. 79" complex. He has integrated and coordinated various professional disciplines, including architecture, interior design, landscape, façade, and lighting, to oversee the entire process and ensure the outcome. The project officially commenced construction in April of this year, with the lower section soon reaching completion, and it is expected to be progressively completed by the end of 2025.

Chengdu possesses a strong spirit of inclusivity, where internationalism and vivacity seamlessly coexist with the local culture. In this renewal project, I aspire to go beyond mere physical space integration and, more importantly, to incorporate contemporary lifestyle and consumer experiences, enhancing the vitality of the old city by creating a diverse and mixed urban district.

The project site is in Chengdu's Jinjiang District, near historical landmarks like Niuwang Temple and Dianjiangtai. The East Avenue area, where it is situated, was historically Chengdu's bustling commercial center and gave rise to modern commercial hubs like Taikoo Li and Chunxi Road. Records show that Chengdu's commodity markets have evolved over the years to feature specialized and multifunctional street layouts that include workshops and markets. Among these, East Avenue best reflects the unique commercial culture and landscape of late Qing dynasty. The streets are described as having "spacious stores, exquisite windows, and various signs hanging from the eaves, creating a dazzling and brilliant spectacle," which effectively carries forward the tradition of superb commercial culture in the southwestern region dating back to the Tang and Song dynasties.

Faced with the dual urban demands of preserving history and fostering modern development, line+ has put forth the concept of "weaving urban textures and nurturing district coexistence" for the old city renewal.

On one hand, this involves harmonizing disparate architectural scales, seamlessly stitching the urban fabric, and fostering dialogue between the old and the new to achieve a symbiotic relationship between these contrasting urban districts. On the other hand, it entails blending traditional commercial spatial patterns with contemporary business formats, integrating traditional spatial experiences into new consumer settings, thus providing the city with a novel, mixed-use environment featuring diverse business formats. Leveraging historical and cultural symbols like Dianjiangtai and Jiazi, this project aims to create a significant cultural extension of Chengdu's "Eight Streets, Nine Alleys, and Ten Scenic Spots."


The design begins by introducing a main thoroughfare that runs east to west across the site, connecting the Inner Ring Road with Niuwang Temple North Street and Street Corner Gardens, serving as the inner interface open to the city. Additionally, in the east and west orientations facing the urban block, two corner plazas are created, linked by smaller-scale streets and lanes that align with both sides of the main street, thereby generating low-density urban blocks with traditional streets and lanes scale.

The commercial clusters within the urban block are composed of three fundamental unit blocks that interconnect, overlap, and enclose each other, forming courtyards of varying scales. These courtyards accommodate a variety of activities, including commercial operations, production workshops, and urban gathering spaces, innovatively preserving the compound characteristics of historic commercial streets and lanes.

The two high-rise towers positioned at the ends of the site appear to "float" above the entire block to preserve the integrity of the street-level urban fabric. Overhanging the ground level space, they create a visual corridor between Niuwang Temple North Street, Dianjiangtai East Street, and the Inner Ring Road, establishing a visual dialogue and reducing the sense of urban interface pressure.
The sleek and stylish high-rise towers epitomize the city's development ambition, while maximizing the utilization of ground-level space serves as a valuable compensation for urban public areas. In collaboration with the commercial district, this approach generates urban business opportunities, revitalizes urban vitality, and ultimately fulfills the true purpose of urban renewal.

The façade design of the high-rise towers employs horizontal step-like treatment to the rectangular volumes, along with rounded corners to alleviate the overwhelming scale and optimize internal sightlines. Vertically, the use of metallic materials divides the architectural form with "arches," incorporating the imagery of bamboo's rising segments, presenting a classic charm with contemporary materials.

Within line+'s comprehensive digital Rhino-Revit work platform, the design team efficiently and flexibly addresses complex challenges such as the glass curtain wall's wall-to-floor connections for the high-rise towers, improving design flexibility while controlling the granularity of the entire design expression and implementation to ensure high-quality project execution.

Throughout urban renewal, line+ continuously contemplate how tradition and modernity can blend and evolve. In this project, the design draws inspiration from traditional commercial streets and lanes as spatial prototypes, preserving their historical significance in spatial form while innovatively introducing an open organizational approach to imbue them with modern urban functionality. This project emerges as a paradigm for the creation of mixed urban districts, where the new complements the old, renews tradition, and embraces a modern urban future.
