ONOAA STUDIO

Based in Shanghai, ONOAA STUDIO’s commercial interiors and architectural renovations juxtapose heavy structural elements like concrete slabs and dark stone massing with delicate, precise inserts—ranging from suspended linear light grids to fluid, ribbon-like stair geometries. This work provides a strong reference when detailing commercial spaces that require balancing rhythmic display fins, thin steel perimeter framing, and soft tactile backdrops within rigid structural bays.

What we like about this project
The staircase underside is seamlessly integrated with the ceiling cut-out above, creating a continuous white ribbon effect.
