São Paulo, Brazil · 1992

A precedent for monumental urban infrastructure, demonstrating how a suspended steel canopy can define a public plaza and shelter transit access without obstructing historic sightlines.
- What we like about this project
- The canopy's aerodynamic, wing-like curvature appears to float weightlessly despite its massive steel construction.

- Geometry
- A monumental, cantilevered steel canopy with a curved, wing-like profile is suspended from a massive overhead portal frame spanning the plaza.
- Structural guess
- Suspended steel plate structure hung from a primary steel box-girder portal frame.
- Spatial scale
- Large civic scale; the overhead portal frame rises to approximately three stories in height, framing the pedestrian plaza.
- Lighting
- Bright, direct daylight casting sharp shadows on the mosaic pavement, with the underside of the canopy in soft, reflected shadow.
- Atmosphere
- A dynamic, sunlit urban gateway balancing heavy historic architecture with light, expressive modern engineering.
- Environmental context
- A bustling historic city square in São Paulo, flanked by classical mid-rise stone buildings and active pedestrian traffic.
- Spatial experience
- The canopy creates a sheltered, open-air transition zone over a subterranean entrance, compressing the scale of the vast public plaza while maintaining clear sightlines across the city.
- Composition rhythm
- The horizontal sweep of the canopy and portal frame contrasts with the vertical rhythm of the surrounding classical facades.
