The Prisma Tower renovation project led by investor Ivanhoe Cambridge was awarded to Axel Schoenert Architectes Associés.

The objective of the restructuring of this 27,488-square-metre building was :

  • to provide new visibility and identity to the Prisma Tower,
  • to make it competitive in the face of the big project at hand,
  • to integrate it via certification and labeling in the sustainable development approach.

The choice of materials and the layout of the spaces offer great organisational flexibility in convivial and elegant spaces.

This project is part of an environmental approach by providing for a double certification HQE Exploitation and LEED Existing Building.

This tower was delivered in June 2011.
