The Lucie Aubrac Residence in Évry, South of Paris| White Concrete

Under the project management of 1001 Vies Habitat, the Lucie Aubrac Residence, a social housing project in Évry, South of Paris, designed by Fabienne Guérin-Jean, is currently under construction.

The building façade combines grey concrete at the ground level with white concrete above. Aalborg White CEM I 52,5 R DK cement was used in the cast-in-situ concrete, with the concrete surface left in their raw, as-cast state, requiring meticulous execution. To ensure consistency in finishes across different weather conditions, the contractor employed latest in-house B20 stainless steel formwork and a bio-based, highly aqueous white release oil.

The façade also features deep grooves at each window level, creating a cohesive rhythm throughout the buildings. This design echoes the aesthetic of the ground floors, which are characterized by a series of arched patterns. The polyurethane magnetic matrices system was utilized to ensure uniformity in the window groove detailing, which can be reused up to 45 times!

In total, approximately 874 m³ of architectural white concrete was used for this project. The contrast between the light upper levels and the darker base enhances the building visual impact. Additionally, the engraved façades elevate the overall design of residential buildings, seamlessly blending durability with architectural elegance.
