French engineer Eiffage has won a €92m contract to renovate the 25,000 sq m “Cristallis” project in northern Paris’ ninth arrondissement.
The three buildings that make up Cristallis will in upgraded, and one will be extended. They are mixed-use, with offices, co-working spaces, a restaurant and auditorium across nine storeys and seven underground floors.
Eiffage will take care of the extension and elevation, as well as façade replacements, foundation works and restructuring of all three buildings.
Cristallis will also be brought up to the energy efficiency objectives required by the Eco-Energy Tertiary system. Secondary construction materials and natural resources will be reused and photovoltaic panels will be installed on the roof, which it is hoped will give it a BREEAM Excellent rating.
Construction has begun and is due to be completed by the end of 2025.
