Tour Duo rises at the gateway to Paris’s 13th arrondissement, a pair of office towers completed in the early 2020s as part of the city’s ongoing urban renewal. The twin volumes play with asymmetry — one tower taller, their copper-toned facades catching light differently throughout the day.

The cladding breaks into rhythmic vertical fins and glazed strips, creating a moire effect that shifts with viewing angle. Black and white emphasizes the interplay of shadow and reflection across the faceted surfaces.
