Tour Bretagne

The new Tour Bretagne, a renovation of the emblematic Nantes landmark, offers an opportunity to transform a symbol of the postwar boom, now obsolete, by adapting it to the challenges of our time. The PCA-STREAM – MAGNUM team enhances its elegance and slenderness by converting office spaces into housing, making the project a forerunner of a new era for the city and the metropolis.

The Link

PCA-STREAM was tasked by Groupama to design an innovative tower that will renew the image of La Défense. Revisiting the model of the traditional tower, The Link is emblematic of the transformation of working practices and a new relation to the city. Its morphology in two wings connected to one another with platforms called “links” allows the tower to provide spaces that foster interactions and collective intelligence, and gives an unprecedented place to nature in a high-rise building.
