IILab. fashions cloud-like bamboo canopies and lantern-shaped pavilions in China

Since its inception in 2004, Impression Sanjie Liu - a night light show staged along the banks of the Li River, has become a local tourist attraction in Yangshuo County near the city of Guilin in the Guangxi Zhuang Autonomous Region of Southern China. Named after Liu Sanjie, a folk singer of legendary repute in the area’s history, the breathtaking display consists of seven scenes with hundreds of performers using the backdrop of the Li River as the largest natural auditorium in the world. Regarded as one of the most dramatic landscapes on view throughout the vast nation of China, the area is enclosed by soaring tower karsts of rock, with an abundance of lush vegetation spread between them. In order to augment the visitor experience for this scintillating spectacle, Shanghai-based studio IILab. was enlisted to formulate an intervention that would complement the picturesque natural setting while offering a more formal point of interaction and gathering for viewers.

Due to their reverence for the incredible natural beauty on view at the site, the architects sought to develop a statement that would leave the natural ecosystem unharmed while shaping a pre-existing condition of the location to their advantage. As a consequence of the dense growth of bamboo within the area, there were naturally-occurring clustered and tangled structures which lent themselves well to the needs of the project. “To coincide with what is already there, the new architecture looked at borrowing the materiality of the bamboo, reconfiguring it to form new a space. In doing so, this new space means not to contest. Instead it aims to augment, albeit very gently, the surrounding bamboo groves and hills,” shares IILab. in an official statement.

Having identified the two main points where guests are entertained as part of the display - namely the entrance and pagoda, along with the main stage on the riverbank, the designers resolved to place their intervention between them, creating a new zone of interaction that would provide for a more holistically engaging experience. In this intermediate space, the team at IILab. formulated two new architectural systems using the unique qualities of bamboo construction. Scattered across the space where visitors normally circulate, a series of lantern-shaped woven bamboo pavilions form the first segment of the intervention, followed by a sweeping woven bamboo canopy, which grants shade from the sun and rain. "Here, the architecture relies on bamboo not only for its composition, but also as a constant reference to elements that constitute the context," note the designers.

Miniaturised versions of the woven lanterns are initially encountered at the entrance, gradually enlarging in scale on moving further towards the main stage. After a certain point, the pavilion-like structures become large enough to enter, consisting of lengths of bamboo lashed together, encased within a thin layer of bamboo strips threaded over by craftsmen to create a lattice-like envelope. Seemingly random patterns in the layer are a product of the craftsmen’s own sense of aesthetics and functionality, which permit the woven covering to hold together without the use of any glue or nails. The bamboo lengths in the underlying structure appear darkened in some portions - a sign of how the material is treated with fire to form the curved profile of the lanterns. In essence, this exercise in pavilion design is a reflection of the exemplary intricacy of individual craftsmanship, by the hands of local residents.

Radiating a delicate yellow aura, the lanterns appear almost solid during daytime, due to the sheer volume of threads and the complexity of the perforated envelope. On the other hand, the structures diffuse residual light after the sun has set, behaving like porous shells. Furthermore, their arched profiles evoke the massing of tower karsts in the background - a further hint at how the bamboo design intervention is truly a product of its surroundings.

Ahead, the grand bamboo canopy presents itself, its sheer enormity reminiscent of an object of fantasy. Extending for 140m, the structure is encased in a similar woven bamboo sheath, and seems to almost float above the landscape as a cloud-like second layer, held up only by a few columns of intertwined bamboo that rise up towards circular cutouts in the canopy. In actuality, these structures conceal metal columns and footings that have been designed and painted green to blend into the setting. The undulating geometry of the bamboo architectural forms echo in the landscape below, while allowing dappled light to stream into the clearing it shields during the day. This effect gives the ceiling a gentle glow, radiating a sense of otherworldliness - in keeping with the dramatic natural beauty on view throughout the area.

At night, the light introduced to the clearing beneath the canopy creates intense shadows on its ceiling that dance and sway much like the performers on the riverbank. Interestingly, as per the architects, a number of other elements of the cultural architecture project acknowledge this connection to the performance of Impression Sanjie Liu, such as the hand woven bamboo held together by the tension of each thread, the sinuous profiles of the canopy, or the pathways between lanterns which forge a 'narrative of interaction'. The architects relay, “Together these subtle hints encourage a particular frame of mind, readying the guest for the main feature.”

Selected as the winner of the ‘Small building of the year’ category at the Dezeen Awards 2021, Bamboo Bamboo, Canopy and Pavilions, Impression Sanjie Liu, harnesses the adaptive qualities of a trendy material in the realm of sustainable architecture to create spaces that offer a taste of local folklore and spirit. The public installation's naturalistic qualities allow it to become one with its context rather than impinging on it, while fashioning an ethereal experience befitting its monumental setting.
