Rehabilitation, as part of the Climate Plan, of a high-rise housing tower on an occupied site in the Beaugrenelle district
The H15 tower, built in 1979 by Michel Proux and composed of 192 apartments, represents the Parisian symbol of the triumphant and unbridled town planning of the thirty glorious years. However, the district has aged badly and the slab has many malfunctions.
The rehabilitation of the tower meets two needs: the renewal of the image of the building and the search for high thermal performance. His observation made it possible to break down its geometry into several simple volumes with differentiated hues. In this way, the tower appears as a set of buildings embedded in each other around a central core, allowing to find more slender proportions.
A second operation consists of covering the railings with anodized aluminum cladding. The ovoid proportion of the existing balconies is retained to preserve the image of the project and maintain the unique views of the Parisian landscape from the accommodations.
The natural anodized aluminum restores a slight shine to the facade elements while avoiding the effects of reflections and thus preserving the domestic image of the building. The contrast of this material with the coating will preserve the molding elements and the specific volumetry of the Beaugrenelle tower while allowing it to dialogue more strongly with the surrounding towers and buildings.
Finally, the entrances and common areas of the tower have been reworked with respect for the original work. A new lobby clad in perforated metal panels is added to the ground floor to provide residents with a nobler space and signal the entrance to the tower from Linois’street.
