Charles B. Johnson's mansion

This gated French château-style home sits on 2.5 acres in one of Palm Beach’s most desirable areas, on the waterfront near the Bath & Tennis Club and Mar-A-Lago. The 27,300-square-foot residence was completed this spring by Dan Swanson, president of Addison Development, and has eight en suite bedrooms, nine bathrooms, a 60-foot pool, a separate guesthouse and room to park 50 cars.
