This Formentera home, designed and owned by the famed fashion designer Consuelo Castiglioni, is my idea of a perfect hideaway. To the very last detail. I envision relaxing days reading a book and lounging by the pool, and evenings spent hosting fun dinner parties. The earth tones create a soft palette that allows the space to breathe, with the odd hint of color and eye-catching pieces littered throughout the home.
