Hannes Peer and Margraf's La Casa di Marmo at Milan Design Week 2026

For Milan Design Week 2026, architect Hannes Peer and the stone company Margraf transformed an underground garage beneath a historic villa's garden on Via Cernaia 1 into La Casa di Marmo, a fully marble-clad domestic space. The project uses Santafiora marble from Manciano in Tuscany for all surfaces, with translucent stones like onyx and quartz treated as paintings. With no natural light, Buzzi & Buzzi created an artificial lighting scheme using zenithal and backlighting to simulate daylight. A central patio features a blade of light and a water sheet, referencing Roman villa courtyards, with sculptures in a reflecting pool. The water installation was the biggest technical challenge for Margraf. The space includes a conversation pit with backlit onyx by Taurini Pianeta Gemme and upholstery by Nalesso. Peer emphasized the collaborative process with Margraf's young management team.
