‘Il Sonno’ turns stone dreamy

A supermarket made of stone sounds like a joke until you see what SolidNature and OMA’s research arm, AMO, built for Milan Design Week 2026: shelves, groceries, and domestic scenes turned into heavy, geological theater called “Il Sonno.” (designboom.com) The installation sits inside “Room for Dreams” at ME Milan Il Duca, the Aldo Rossi-designed hotel that designboom is using as a weeklong exhibition site during Milan Design Week, which runs April 20 to April 26, 2026. (designboom.com, comune.milano.it) The basic move is simple: take the most disposable setting in daily life, the grocery store, and rebuild it with one of the least disposable materials humans use. David Mahyari described the project as replacing common household goods with stone artifacts so shopping starts to feel like moving through geological time instead of a quick errand. (designboom.com) That contrast is the whole point of SolidNature’s business. The company works in natural stone and has spent the past few Milan design weeks asking architects to treat marble, onyx, and travertine less like luxury cladding and more like a design system with its own logic and limits. (solidnature.com, oma.com) OMA and AMO matter here because they split the job in a useful way. OMA is the architecture practice, and AMO is the branch that handles research, exhibitions, and cultural analysis, so a project like “Il Sonno” can work as both a room you walk through and an argument about how people consume objects. (oma.com, designboom.com) This is also not their first stone experiment together. In 2023, SolidNature commissioned OMA for “Beyond the Surface,” an installation about stone’s path from geological formation to finished product, and “Il Sonno” reads like the next step: less about extraction and fabrication, more about what happens when stone invades ordinary life. (oma.com, solidnature.com) Milan Design Week is the perfect place for that argument because the city turns design into a temporary urban stage every April, with hundreds of exhibitions competing for attention and more than 300,000 visitors passing through the fair alone. In that setting, making a supermarket feel like a ruin from the future is a good way to stop people in their tracks. (forbes.com, comune.milano.it) The name helps too. “Il Sonno” means “sleep” in Italian, and the installation leans into that dreamy mood instead of presenting stone as cold or purely monumental, which is why the project lands somewhere between stage set, retail parody, and memorial to everyday objects. (designboom.com) What you end up with is a design installation that asks a blunt question without spelling it out: if a loaf of bread, a shelf, or a checkout counter were treated as if they deserved the lifespan of a building, how different would daily life look? “Il Sonno” answers by turning the quickest acts of consumption into scenes that feel built to outlast us.
