France: The villa Navarra and its Ductal® roof, a world first!

Hidden away in the hinterland of the Var coastline (France), the building realized for the art dealer, Enrico Navarra, nestles into the slope so as to blend into the natural vegetation of the Provencal landscape.


The villa Navarra practically boils down to its roof: an immense visor stretching 40 metres between the trees, with a cantilevered surface of 7.80 metres opens up the house to the wild landscape.
An exceptional work, both aesthetically and for its technical complexity, this ultra-thin roof made of Ductal® concrete is a world first. It is the fruit of the boldness and expertise of Rudy Ricciotti, laureate of the National Architecture Grand Prix 2006, Romain Ricciotti, structural engineer, and Lafarge teams.
The ultra-high performance fiber-reinforced Ductal® concrete has innovative properties and, once again, is capable of the most impressive of architectural feats.
