Studio Symbiosis's competition proposal for a multifunctional building beside Zaha Hadid's MAXXI Museum combines art storage, labs, a café, and a rooftop garden bar overlooking the museum's roofscape. A landscape reconfiguration of Via Masaccio extends the museum's curvilinear language into the public realm. Built on circular economy principles, it uses recycled demolition materials, steel-and-timber structure, and geothermal energy. Site Area: 5,080 sq.m. Built-up: 9,482 sq.m. Status: Competition.
