Inside, expansive rooms support refined living and elevated entertaining, with multiple viewpoints capturing the surrounding hillsides. Signature amenities elevate the experience, including a 20-car showcase car barn, an inviting club room and a temperature-controlled wine cellar—ideal for collectors and connoisseurs.
