Anna Saint Pierre's Granito project is harvesting the ingredients for new architectural building blocks from demolished structures.
Rapid urban change comes and goes without many even noticing it. Entire slices of a city’s history disappear overnight: What was once a wall of hewn stone is now fritted glass and buffed metal. The building site is always, first, a demolition site.
This is the thread that runs through Granito, a project by the young French designer and doctoral researcher Anna Saint Pierre. Developed in response to a late-20th-century Paris office block due for a major retrofit, one involving disassembly, it hinges on a method of material preservation Saint Pierre calls “in situ recycling.” Her proposal posits that harvesting the individual granite panels of the building’s somber gray facade could form the basis of a circular economy. “No longer in fashion,” this glum stone—all 182 tons of it—would be dislodged, pulverized, and sorted on-site, then incorporated into terrazzo flooring in the building update.
