Title: Pierre
Description: The announced exhaustion of raw materials -- first and foremost sand, an indispensable component of concrete -- invites us to rethink the dominant construction methods of contemporary Ile-de-France housing. In view of the studies undertaken to find innovative materials that are more economical and imported technologies more virtuous, the exhibition-research "Pierre" challenges the raw material of Paris -- its chalk floor and its limestone history. Only stone construction offers a local, natural, well-founded and proven response. The energy saving linked to its implementation is combined with the proximity of the deposits. It only takes a few cuts to turn the rock into material and a few hours to go from the source to the site. The study of the ten quarries of the Parisian geological basin (still productive in limestone) demonstrates the availability of the resource.
