At Qiantan Leisure Park on the east bank of the Huangpu River in Shanghai, XISUI Design was invited by Lab D+H SH to participate in developing a series of public pavilions and corridor landscape installations shaped like cedar cones.
In early 2025, Shanghai’s Qiantan Leisure Park on the east bank of the Huangpu River underwent a comprehensive renewal. Lab D+H SH won the bid for the overall landscape planning and design, and XISUI Design was honored to be invited to participate in the development of cone-shaped landscape installations and children's play areas. The core landscape design theme proposed by Lab D+H SH is "Urban Bald Cypress Forest," centered around the existing well-preserved bald cypress trees on site.
Phase One has delivered two bald cypress cone-shaped installations—one large, one small. The bigger installation resembles a ripe cone lying on the ground, about 3.8m tall and 8.5m in length and width. It is an open-ended, roofed corridor with a continuous loop-shaped cross-section.
The installation itself was further refined through XISUI Design’s expertise in parametric design. Several circular ring beams are linked by strip-shaped keels to form the overall framework. Inside, preservative-treated timber planks are tightly fitted to create a smooth curved surface—within the lower section of this curve, the material flows and extrudes to generate a long bench. Externally, preservative-treated merbau timber is crafted into multi-layered, staggered wooden shingles of varying lengths, mimicking the textured form of the bald cypress cone. Algorithm-driven surfacing and keel design achieve a fluid, biomimetic shape while making precise on-site fabrication convenient. The naturally welcoming texture of the treated timber used for the exterior fills the site with a fresh, lively atmosphere; set against the adjacent bald cypress grove and garden greenery, it feels like stepping into a fairy tale world.
As a pavilion, this horizontal bald cypress cone installation wonderfully integrates with the surrounding bald cypress grove, urban promenade, and flower gardens. To its west, across Qiantan Park, it opens up directly to the Huangpu River; to its east, across Qiantan Avenue, it faces the modern, upscale, and vibrant Qiantan Park Lane. This unique position makes it a striking, harmonious T-junction where modern commerce and nature contrast yet blend remarkably—infusing the space with a lively, everyday charm.
The smaller bald cypress cone installation is situated on the northern side, about 20 to 30 meters from its larger twin. Temporarily serving as a tea beverage stall, its environment-integrated design and functional role provide a distinctively designed outdoor area for enjoying a refreshing tea break.
When we returned to photograph the completed installation, we saw people of all ages strolling, relaxing, and taking photos here—posing with the cedar-cone installations and gardens, capturing artistic portraits. In this megacity of Shanghai, visitors have left behind precious “urban walk” memories, while local residents have effortlessly embraced this new space, weaving it into their daily leisure routines.
