Designed by architect Paul McClean, the McLean Carcassonne House is more like a private resort than a residence. The modern estate offers nine luxurious suites along with a hair salon, fitness center, wine cellar, cinema, and a wellness spa with its own massage studio, facial room, and yoga meditation center. Its opulent 28,000-square-foot interior also features a 25-foot foyer, complete smart home system, and a sleek array of contemporary fixtures and marble finishes. Signature full-height glazing opens out to an expansive terrace where you'll find oasis-style landscaping enveloping a 160-foot swimming pool and a 30-foot water wall. It's all privately situated on two acres in the hills of Bel-Air.
