Few homes make as much of a first impression as The Hangar. Designed by the Austrian artist, Reinhold Traxl, it’s a converted warehouse that might seem more at home in Brooklyn than in the Tuscan countryside. You wouldn’t expect to be a half-hour drive from Siena. Overall, it feels like an installation as much as a home, and yet never impersonal. The sculpture garden is a real highlight, as are the views over the ruins of Castello Montelifré. True, if you’re set on a traditional farmhouse, you might be slightly shocked, but this is the kind of unique, design-led home that doesn’t come around very often.
