Stone dream at Milan

A fake supermarket made of stone is one of the stranger sights heading into Milan Design Week 2026. “Il Sonno” swaps everyday goods for carved stone objects and turns grocery shopping into a walk through geological time. (designboom.com) The project comes from stone brand SolidNature and AMO, the research and strategy arm of Office for Metropolitan Architecture, the architecture firm founded by Rem Koolhaas. Designboom says the installation debuts inside its “Room for Dreams” program in Milan. (designboom.com 1) (designboom.com 2) Milan Design Week runs across the city from April 20 to 26, 2026, with hundreds of exhibitions layered around the Salone del Mobile furniture fair. Fuorisalone’s official guide lists 863 events, which helps explain why brands now build full environments instead of just showing products on pedestals. (fuorisalone.it) (designboom.com) “Il Sonno,” which means “sleep” in Italian, is built around a simple reversal: the shopper becomes temporary and the product becomes permanent. SolidNature owner David Mahyari told designboom that the stone supermarket goods “are staying forever,” while visitors are the ones “coming and going.” (designboom.com) That idea lands harder because stone is the material doing the talking. Designboom says the installation uses more than 40 varieties of stone, so the shelves and surfaces read less like store fixtures and more like a museum where the exhibits forgot to stop being useful objects. (designboom.com) This is not the first time SolidNature and Office for Metropolitan Architecture have used Milan to make stone feel cinematic. SolidNature’s own archive says the pair worked together on an earlier Milan Design Week exhibition that led visitors through seven spaces about compression, solidification, extraction, and finishing. (solidnature.com) That earlier show covered more than 500 square meters in Casa Maveri in the Brera district and used a sky-blue onyx entry and a multicolored marble staircase to make visitors feel as if they were descending under the Earth’s surface. The new project keeps the same instinct: don’t explain the material with a brochure when you can make people walk inside the idea. (solidnature.com) The fashion-adjacent part is the scale and staging. Designboom’s “Room for Dreams” program at the ME Milan Il Duca hotel mixes installations, film screenings, talks, and brand collaborations, which puts stone in the same conversation as image-making, hospitality, and cultural programming instead of just countertops and cladding. (designboom.com) AMO is useful here because it sits on the border between architecture and narrative. When a research studio known for exhibitions and brand thinking teams up with a stone company, the material stops being a finish and starts acting like a script. (designboom.com) (solidnature.com) So the real subject is not a supermarket at all. It is the gap between a plastic bottle designed for a week of use and a slab of stone that has already lasted millennia, staged in Milan from April 21 to 26 at Piazza della Repubblica 13 as a design event you can physically enter.
