The Cristal is an urban piece but also a landscape piece, heir to a history that dates back to the ancient landscapes of Nanterre. Reinterpreting the scale of today’s buildings, it offers new sensations of nature in this climate that will preserve the biodiversity of the natural environments of the city of Nanterre.
The 12-story tower is marked by a transparent bow that captures sunlight and gives this block its crystal character. Its angles are fragmented, broken and sawn to reflect flashes of crystal-like light. The tower and the Allée de Corse are connected  by a series of cascading terraces. The alley is bordered by cafes and shops which offer direct access to the forum. A fluid architectural promenade connects the main alley and the forum, the heart of this future dynamic district.

The crystal incorporates the landscape architecture with the rise-tower one; offering to Nanterre a new architectural icon that symbolizes the future sustainability of the neighborhood and the city. This nature is the confession of the moment, the fleeting revelation, the consciousness of time that passes, the emotion of the seasons. Nature as a positive counterpoint to the urbanization of the city. The gardens are privilege spaces, the nobility of the city, the nature accompanies the reliefs of the project.

The Crystal is a housing project that includes three emergences on the same block: a residential tower of 12 floors, another of  9 floors and a last one of 7 floors; all rest on a business common pedestal. The tallest tower is the culmination of the «Nanterre, heart area,» which includes the construction of several buildings on the site.
