Project Summary

Vertical Restructuring

High-rise tower rehabilitation

The project revisits a 1970s high-rise in the center of Nantes suffering from the problematic modernist creed of functional separation, which prevents the structure from being integrated into the urban fabric.

The scheme aims to transform the existing structure into a “vertical city”, filled with multiple activities. The proposed design deploys public space as a means to link the existing cityscape with the new public spaces of the tower.
