The materials used are technical products and must be installed according to professional standards. We recommend that the installation be carried out by a professional.
As part of an urban renewal project, an old building from the 1980s was demolished to make way for a new six-story building. The original building, which did not comply with the Local Urban Planning Plan, had structural defects and urgently needed to be replaced. The reconstruction is part of a desire to reinvent the plot, while respecting urban regulations and contemporary architectural ambitions.
The constructive choices of the project
CLT has established itself both for its structural performance, its efficiency during the construction phase and its ability to meet the constraints of a site in the heart of the city.
This construction method reduces the need for on-site storage and allows for rapid implementation. It also limits assembly times and construction site disruptions. These are all decisive criteria for this cramped plot in a constrained urban environment.
CLT was used to create the cross-section floors, allowing large spans to be covered without intermediate posts to free up living space.Left visible on the underside of the floor, it highlights the aesthetics of the wood thanks to its “Excellent” surface quality.
Beyond the 5th floor, wood takes up even more space: the 6th floor extension, which houses a rooftop studio, is entirely made of CLT, both for the floors and for the vertical walls.
The use of CLT in this project
74 m3 of CLT made this project possible, including 71 m3 of visible quality for roofs and floors. Beyond R+5, CLT has several considerable advantages:
Bending strength,
Stabilization of the building,
In association with the floor coverings, its massiveness meets fire and acoustic regulatory requirements.
The CLT made it possible to meet the challenges of a very constrained construction site, requiring the use of a crane inside the building: the floor layout was adapted accordingly, and the last panels were installed manually, without using a crane.
