These jaw-dropping houses are pieces of art—and you can rent them

Solo Houses, a stunning and ambitious architectural project, is taking shape in the Spanish countryside.

Christian Bourdais and Eva Albarrán are building what may be the most interesting architectural project on the planet: a collection of 16 extraordinary buildings sprawling more than 425 acres in the stunning sierras of Teruel, near the town of Matarraña, Spain. Think about it as an art collection in which the artwork is full-scale, fully-functional homes designed by some of the most interesting architects of this generation, with no creative constraints whatsoever. The name of this architectural wonderland is Solo Houses.
