3XN's River-Shaped Shenzhen Natural History Museum Opens

The Shenzhen Natural History Museum opened on July 28, 2026, beside Yanzi Lake in Shenzhen's Pingshan District — a 1.13-million-square-foot building whose curving walls trace the bends of the nearby Pingshan River and whose roof is a public park that requires no ticket.

Danish studio 3XN led the design, working with B+H Architects and local firm Zhubo Design. The team called the scheme Delta, after the river landscapes that inspired it. At 105,300 square meters, it is now South China's largest natural history museum. The project arrives six years after it first appeared as a set of competition renders in 2020.

What does the building look like?

From above, the museum reads as pure river geometry. Walls swing out in long bends and curl back, leaving crescents of lawn and trees tucked inside each loop like oxbow lakes. Five rounded volumes — the galleries — sit along the curve like smooth stones the current left behind. Paths run along the tops of the walls the way a riverside trail follows water.

The facade is built from vertical fins of Shandong granite, packed so tightly the surface reads like rock weathered by rain over millennia. The fins shade the galleries while still admitting daylight — a meaningful advantage in Shenzhen's subtropical heat. At sunset the stone turns warm and peach, and each ridge throws a thin stripe of shadow down the curve. Most panels are standardized, so a damaged fin can be swapped out without anyone noticing.

Wide arched openings cut through the stone like the mouths of sea caves. The main opening sits on the south side and links the busy street to the wetland park behind the museum, so the front door doubles as a shortcut into nature. Reflecting pools in front give the arches mirrored twins. 3XN describes these openings as fissures in the cliff.

What is inside the five cones?

The galleries sit inside five enormous cones. Inside, gray granite gives way to golden marble: each cone is wrapped in wood-grain marble from Guangxi, striped like layers of sediment. Between the cones, a central atrium rises toward a large rooflight, and a spiral staircase climbs the core in wavy, uneven rings. The architects named the atrium the Tree of Life, and the stair branches off onto each floor.

The roof slopes up from the ground like a grassy hill and is split into five garden zones, ranging from succulents and tropical plants to species drawn from Chinese literature. At its tallest point the building reaches 118 feet (36 meters), but roughly half of it stays low to match the neighboring school and convention center — keeping the mountain views to the north open. The roof is also set up for nighttime stargazing.

The muted massing suits the institution's purpose. The exhibits inside trace how water, rock and time shaped the planet, and the architecture tells that same story from the outside before a visitor reads a single label. In a city known for megaprojects that shout for attention, the museum argues that a 1.13-million-square-foot building can speak in curves, warm stone and a whole lot of grass — and still be the most approachable thing on the block.
