Antonia Jannone moves away from the classic circuit of the big names in Milan – Mendini, De Lucchi, Branzi & Co. – to welcome the watercolours of Steven Holl, New York-based architect who built the horizontal skyscrapers for Vanke in Beijing and other giants around the world. As often happens in these cases, the poetic lightness of the watercolours tones down the solid concrete masses of the real world. A project curated by Marco Sammicheli. Opening hours: Tuesday – Saturday, 15:30 – 19:30; mornings by appointment only.
