Nine-Square Pavilion by Atelier FCJZ: A Glass Tea House by Tai Lake

The Nine-Square Pavilion by Atelier FCJZ is a contemporary architectural gem located within the serene Bogongdao Ecological Park in Wuxi City, Jiangsu Province. Perched near Qinyin Bridge, the pavilion offers a unique dialogue between built form and natural scenery. To the east, it enjoys expansive open views; to the west, a tranquil bamboo grove; while only ten meters to the south lies Li Lake, an inner extension of Tai Lake, framing the pavilion with exceptional lakeside vistas. Designed as a tea house, the project embraces the surrounding landscape through a delicate interplay of transparency, reflection, and modular spatial design.

Materiality and Transparency: Redefining Glass Architecture

Glass in modern architecture often prioritizes transparency, creating spaces where the material itself seems invisible. In contrast, the Nine-Square Pavilion reasserts the material presence of glass, transforming it from a mere visual medium into an expressive architectural element. The pavilion’s glass partition walls are layered and interleaved to produce varying degrees of transparency, serving simultaneously as a physical boundary and a reflective surface that interacts dynamically with natural light. Visitors experience the shimmering reflections of the surrounding lake and bamboo, creating a spatial dialogue between interior and exterior environments.

Morphing Pavilion: The Nine-Square Grid Concept

Inspired by the traditional Chinese JiuGongGe or Nine Palace Grid, the pavilion embodies transformation and spatial flexibility within a 3x3 modular system. Each square measures 3.3m × 3.3m, forming a total of nine units that can be reconfigured according to usage scenarios. The roof is elegantly supported by twelve slender round steel columns, positioned at the intersections of the grid, while 24 glass sliding doors along the grid lines create a movable system of partitions. This allows the pavilion to morph between fully enclosed interior spaces and semi-outdoor squares, providing visitors with varied experiences of enclosure, openness, and connection to nature.

Experiencing Nature Through Reflection

Whether inside the pavilion or under its extended eaves, visitors are immersed in a unique visual experience. The layered glass surfaces reflect the gentle ripples of Li Lake, creating a mesmerizing effect where water, sky, and bamboo visually interlace. This design blurs the boundaries between inside and outside, offering a contemplative retreat that harmonizes modern architectural techniques with traditional Chinese patterns.

Sustainable and Contextual Design

Beyond aesthetics, the Nine-Square Pavilion responds to its ecological context. Its lightweight steel and glass construction minimizes site disturbance while maximizing adaptability. By incorporating movable partitions, the pavilion promotes multifunctional use, from tea ceremonies to intimate gatherings, all while respecting the park’s natural environment.
