The impending depletion of raw materials, first and foremost of sand, an essential component of concrete, has compelled us to rethink much of how we construct contemporary housing in the Ile-de-France. In view of the search for more economical, innovative materials and more virtuous, imported technologies, the exhibition and research project “Stone” considers Paris’ primary raw material: its chalky ground and history of limestone.
Several pioneering architects, builders, and developers in the Ile-de-France have reintegrated stone in their construction processes. Their recently completed projects explore yesterday’s potential and create a language for tomorrow. They mix materials and techniques to reinvent our modes of habitation. Others have increasingly begun to envision a vernacular architecture of the near future that is taller, more open, and more generous. The inventiveness of their constructions does not fully supplant the use of corrupted materials, but it does generate a comprehensive industry of available bio-sourced materials for building the Metropolis.
Stone is a symbol of ownership and perpetuity. The exhibition "Stone: the revelation of a resource and the exploration of a material", curated by the Pavillon de l’Arsenal in conjunction with the architecture firm of Barrault Pressacco, intends to demonstrate the virtuous nature of stone in support of the goal of sustainably building 70,000 housing units per year for Grand Paris.

The book presents a study of the ten or so quarries of the still productive Parisian geological basins, studies the energetic value of the bearing stone and references a selection of semi-load bearing stone works that respond to a program and to urban situations. complex.
Their reflection combines a forward-looking approach to recurring problems.
The question of seeing the new through the prism of history and tradition, the order of assemblages and construction, the contextual and the abstract, are the vectors that organize their project-building processes.
Far from a photogenic, individual rhetoric, their production finds its place in a collective architectural dimension. The project is not a heroic and solitary deed, but an answer to an existing question. Construction and the territory of Greater Paris are two of the agency’s main themes of reflection. Combining them in-depth, in the twin issues of territorial belonging and complementarity, appears to them to be one way of answering many contemporary issues.
Three major partners have joined Barrault and Pressacco in their research:
- The CTMNC, Centre
Technique des Matériaux Naturels de Construction is providing all the necessary
documentation on the subject of stone materials.
- The SNROC, Syndicat National des Industries de
Roches Ornementales et de Construction will assist them in exploring the sector
and understanding its potential
- BRGM, Bureau de Recherches Géologiques et Minières will be giving them full access to the various cartographic archives to understand and maximise the Parisian basin substrata.
