The Jiuliudu Riverside Art District, co-hosted by UUA design partner Li Yongzheng and management partner Li Qizhi, was completed and delivered in September 2023 after five years of design and construction. Situated along the Jiuliudu River in Jinghu New District, Shaoxing, Zhejiang, the project embraces flowing architectural and landscape forms that harmonize with the winding textures characteristic of Jiangnan water towns, seamlessly integrating into the urban fabric with a gentle approach.

1.0 Project Background

Shaoxing Jinghu New District serves as the city’s administrative, economic, cultural, and sports hub. The area boasts a rich water network and an excellent ecological environment, surrounded by lush greenery. This project is strategically located in the core of Jinghu New District, adjacent to the financial office area, and directly faces the Shaoxing Administrative Center and Shaoxing Library across the river, making it a highly significant and sensitive site.

The design emphasizes low building density and height, prioritizing landscape integration. Functionally, the development is positioned as a mid-to-high-end commercial support facility. The three above-ground floors accommodate service-oriented commerce, dining, and boutique hotels, while the underground floor includes parking and mezzanines to support logistics for the catering spaces above.

2.0 Resonance: Geographic Features and Cultural Symbols

“As our second project in this area, this opportunity allows us to deeply explore urban integration — embedding design into the city fabric, connecting neighboring plots, and resonating with the community.” – Li Yongzheng

Jinghu New District’s landscape is defined by a winding water network and rugged terrain, typical of a Jiangnan water town. The site is flanked by a financial complex rising over 100 meters to the west and the nearly 30-meter-high Shaoxing City Library across the river to the east, together forming an “urban valley.”

UUA employed a landscape-driven design strategy, creating fluid architectural podiums and site landscapes. Five “Orchid Pavilions,” inspired by the “three-petal orchid” shape, reference Shaoxing’s water town geography and cultural heritage of orchid cultivation through clear architectural language. The distinctive rooftop forms also offer scenic views over the neighboring high-rises.

3.0 Dialogue with Surrounding Buildings

The site is narrow, spanning approximately 280 meters north-south and 70 meters east-west, surrounded by buildings with diverse functions. The design addresses this complexity by serving as a transitional connector that effectively links adjacent land parcels.

To the north, adjacent to the Shaoxing Administrative Center—a sensitive and important location—two “Orchid Pavilion” buildings are designed with low density and height to minimize visual impact. The south side, bordering Suning Plaza Shopping Center, features three “Orchid Pavilions” supported by continuous podiums to increase commercial density and accommodate foot traffic.

On the west side, the twin-engine building designed by UUA faces east toward the river. To harmonize spatial relationships, an axial plaza aligns with the main entrance of Shuangqing Building. Architectural forms flank both sides of this square, creating a classic architectural sequence. Additionally, the riverbank is concavely shaped along this axis to channel water into a bay.

Across the river to the east stands the Shaoxing City Library. The design mirrors its white color palette and smooth lines to establish a coherent architectural dialogue.

4.0 Creating Hydrophilic Spaces

The original riverbank was nearly straight and monotonous. To activate the riverside, UUA reconfigured the shoreline with dynamic concave and convex contours. Elevated platforms were introduced at protruding sections, preserving the original riverbank and avoiding costly river fill engineering.

A 3-meter-wide accessible riverside pathway runs along the river, supporting walking, jogging, and cycling. This slow lane connects seamlessly to neighboring plots via underpass walkways at the southern and northern ends, forming a continuous network.

UUA also created two plazas and a corridor between urban roads and the river, fostering a seamless interaction between the surrounding areas and waterfront landscapes, resulting in a more inclusive urban space by the water.

5.0 Geometric Control of Form

Geometric control serves as a technical response to architectural form challenges. The main difficulty was coordinating the regular underground garage grid with the freeform above-ground buildings. UUA addressed this by outlining the building forms with straight lines and tangent arcs derived from the basement axis network, creating a seemingly organic yet rational geometric structure.

The five “Orchid Pavilions” vary in size — three large and two small — creating dynamic architectural forms through mirroring, offsetting, and varied heights. Each pavilion follows strict floor, glass curtain wall, and exterior grille control lines, ensuring precision through geometric rigour.

The exterior grille of the “Orchid Pavilion” is designed with segments spanning 1/6th of a circumference (60 degrees), creating a continuous wave-like pattern. By repeating mirrored groups, the undulating form of the pavilion emerges.

6.0 Curtain Wall Details

Building on the geometric control framework, UUA refined the curtain wall design to ensure a high level of completion and provide detailed guidance for construction teams and curtain wall manufacturers.

The curtain wall’s key structural element is the circular steel pipe forming the inner core of the exterior grille. This core is enveloped by semi-circular solid aluminum plates and rectangular perforated aluminum panels. The perforated panels feature a gradient pattern, producing a transition effect between solid and void that enhances the building’s visual richness. Additionally, the exterior grille provides shading and helps filter out surrounding glass reflections.

7.0 Summary and Outlook

UUA approaches design through emotional resonance, imbuing buildings with a sense of “warmth.” Their integrated geometric methodology advances detailed and overall design refinement, achieving architectural precision. This blend of humanistic warmth and technological accuracy, combined with time and growing popularity, will establish the Jiuliudu Riverside Art District as a new urban landmark in Shaoxing.
