A precedent for infrastructural architecture wrapped in a continuous, twisting copper-strip skin that filters light and provides a sculptural identity to a utility building.
- What we like about this project
- The copper strips twist and bend to form a horizontal louver system over the upper window openings without interrupting the continuous skin.

- Geometry
- A monolithic, twisting monolithic tower where the rectangular floor plates rotate slightly as they rise, creating a warped, ruled-surface facade geometry.
- Facade system
- Louvered copper strip rainscreen wrapped around a concrete core.
- Structural guess
- Reinforced concrete core wrapped in a steel sub-frame supporting the copper strips.
- Spatial scale
- A multi-story utility tower, standing significantly taller than the surrounding rail infrastructure.
- Lighting
- Bright, direct daylight reflecting off the warm copper facade, highlighting the horizontal banding and the twist of the volume.
- Atmosphere
- Industrial and metallic, with the warm copper skin catching the sun to soften its monolithic presence.
- Environmental context
- Situated adjacent to active railway tracks with mid-rise residential or commercial buildings visible in the background.
- Spatial experience
- The building reads as an impenetrable, sculptural object in an industrial landscape, with its metallic skin twisting to selectively reveal or shade the interior.
- Composition rhythm
- Continuous horizontal copper bands wrap the entire volume, with spacing that slightly opens up at the top to form a louvered aperture.
