Casalgrande Padana is once again working side by side with Renzo Piano Building Workshop in the Paris Courthouse project

Casalgrande Padana took part in the Paris Courthouse project by supplying the porcelain stoneware tiles used for the building’s floorings.

“A strange 160-metre skyscraper, a lightweight, bright structure made up of stacked elements. A magical lantern, a levitating presence which conveys a feeling of serenity”, as the designer describes it.

Roof gardens and a stacked design, a building of great impact that, despite its size, presents itself as lightweight, bright, and innovative, even in the sensations it gives visitors.

Casalgrande Padana played a crucial role in this important project, supplying the 21,000 m2 of porcelain stoneware tiles used for the building’s floorings. For the public areas, corridors and bathrooms, RPBW opted for the neutral tones of Grigio Marostica (30x30 and 30x60 cm) and Raggio di Luna (30x60 cm) from the Marte porcelain stoneware collection, as well as the brighter shades of Bianco Assoluto, Bianco B and Grigio Cenere (20x20 cm) from the Unicolore porcelain stoneware collection. These porcelain stoneware tiles perform extremely well in terms of both resistance and practicality, with a total of 21,000 m2 used. They also underline the regular layout of the spaces and create continuity between the interiors.

Located in the recently renovated, eco-friendly district of Clichy-Batignolles, this imposing new building designed by RPBW connects the city to the suburbs and is home to the new Paris Courthouse.

This vertical fortress looms high over the skyline in the north of the city, standing out from the city’s more conventional towers.

The building’s three roof gardens overlook the Martin Luther King Park, providing some sort of continuation. At 160 metres in height, it rewrites the very definition of a skyscraper with its differently sized glazed blocks stacked one on top of the other in a staircase pattern.

We met Stefano Marrano. Here is an extract of his interview.

The ceramics provided by Casalgrande Padana for the interiors feature neutral colours, including absolute white and two shades of grey. Why did you go for those colours? What kind of performance was required in the spaces where the ceramic materials were used?

S.M. “We chose Casalgrande Padana’s ceramics mainly for functional reasons: great wear resistance, easy maintenance, and hygiene. Moreover, these products have a really textured, warm appearance which sets them apart from similar products. It was really important for us to give identity and continuity to the service areas in the Courthouse.

Do French public architecture regulations include any specific performance requirements for ceramics?

S.M. Performance requirements for ceramics (and for all materials in general) depend on where they are going to be used. For flooring, in particular, there are classification systems for the anti-slip treatment of the walkable surfaces and its mechanical, physical and chemical properties: wear resistance, perforation resistance, waterproofing and chemical resistance (UPEC). For food preparation areas (e.g. kitchens), you have to consider hygiene regulations too.”

Once again, this important partnership has been an opportunity for growth and research, which bring to mind other relevant projects for which RPBW has chosen Casalgrande Padana porcelain stoneware tiles. Projects, such as the Niccolò Paganini Auditorium in Parma, Villa Nave (headquarters of RPBW and the Renzo Piano Foundation) in Genova Vesima, Visitors Centre and Santa Chiara Monastery in Ronchamp, the intervention on the Monastery at the service of one of Le Corbusier’s masterpieces, the Ronchamp Chapel, the Pirelli industrial hub in Settimo Torinese, and Columbia University’s Manhattanville Campus.
