A façade with silvery spangle: ST steel panels for a nursery & social housing project in Paris

The project of a nursery school and 12 social housing units in the XI arrondissement in Paris is a sustainable building surrounded by green spaces in the tightly knit urban context. The building's façade is made of ST cladding panels coated with Kristal® and supplied by ArcelorMittal Construction.

Detailed information

The aim of this project was to integrate the new building into the existing green spaces in order to establish a certain continuity with its surroundings of green terraces and gardens with tall trees. The building offers a child day-care centre on its ground floor and 12 social housing units on the upper levels. It is conceived like a box, with its ground floor sliding forward on the plot, opening up a courtyard for the nursery at the back of the building.  Its location at the end of the street next to a park also allowed to create a more protected forecourt for the children and enables the access to the nearby square.

Realized entirely in steel structure, the complex offers maximum flexibility for its internal organization.

The nursery on the ground floor offers a net surface of 300 m2 for 30 children. Its glazed front façade is covered by a protective filter creating the impression of cocoon-like fibre.

The residential part of the building, placed on top of the child day-care centre, creates a single, homogeneous volume thanks to its shape and façade. With a total surface of 1,000 m2, the 12 apartments vary in size and organization, offering 1 to 3 bedrooms with green terraces. Thanks to the reduced common spaces, the size of the apartments could be optimized. Each apartment has windows towards the south, east and west, offering views over the surrounding green spaces.

Sparkling, metallic coated steel cladding panels by ArcelorMittal

The façade of the residential part of the building is made of steel panels. Both siding panels and shutters are made of steel panels ST 440 with Kristal® coating supplied by ArcelorMittal. The panels are assembled with a hollow joint of 10 mm. In order to contrast them from the siding panels, the shutters have linear perforations that let some light through even when they are closed.

The metallic coating Kristal®, an aluminium-zinc alloy that guarantees excellent corrosion resistance, is famous for its aesthetic qualities: its metallic spangle catches the sunlight and thanks to its reflectivity, the building reflects the colours of the surroundings.
