Metamorphosis of the Montparnasse Tower

Finalist among the 700 entries in the international competition for the transformation of the Montparnasse tower, the Nouvelle AOM (ChartierDalix, Franklin Azzi Architecture, Hardel Le Bihan Architectes) has taken up residence in the offices on the 44th floor of the tower. This research and architectural design laboratory dedicated entirely to the project has enabled the team to understand all the issues involved in this metamorphosis. This restructuring is based on programming and the development of attractive uses throughout the tower's verticality: from the 120,000 m² of redeveloped infrastructure to the agricultural greenhouse at the top, including a garden on the 16th floor and a hotel on the 42nd. In 2024, the new Montparnasse tower will be emblematic of Paris' energy transition: a de-asbestosified and rehabilitated tower, low-carbon, passive, which uses the geometry of the existing building to recover the force of the wind at high altitudes and allow natural ventilation of all the interior spaces (this is the "wind façade"). A light and transparent tower, open to the outside and anchored in the life of the neighbourhood.
