a9a建筑设计 a9a architects

Based in Chengdu, a9a architects combines heavy structural massing with soft, light-emitting interior elements across office, lounge, and cafe projects, characteristically employing deep floating roof overhangs, expressive angled struts, and glowing fabric canopies to modulate spatial scale. This portfolio serves as a strong reference when detailing uncolumned cantilevers over public foyers or specifying oversized illuminated textiles and monolithic concrete circulation elements within multi-height commercial interiors.

Exposed concrete building with deep eaves and slender pilotis set against a grassy hill by a9a architects.

A concrete pavilion precedent demonstrating how slender pilotis and deep overhanging eaves create a monumental yet porous connection to a sloping landscape.

What we like about this project
An angled column breaks the strict vertical grid near the upper balcony.

Geometry
Horizontal layered volumes under an expansive flat roof supported by a rhythm of slender external concrete pilotis.
Facade system
Exposed concrete frame with recessed glass walls and cantilevered balconies.
Structural guess
Cast-in-place concrete columns and slabs with long cantilevers.
Spatial scale
Low-rise civic or cultural pavilion with monumental roof overhangs and human-scaled terraced paths.
Lighting
Soft, overcast daylight casting gentle shadows underneath the deep roof overhangs.
Atmosphere
Calm, monolithic shelter embedded within a sloping green landscape.
Environmental context
Hillside landscape with green sloping turf and distant treeline under an overcast sky.
Spatial experience
Approached across an inclined lawn, the structure presents deep sheltering porches and elevated terraces.
Composition rhythm
Repeating vertical columns frame horizontal concrete floor plates and rooflines.
