Property Description
Rare Opportunity on Balboa Island - Just off Marine Avenue, this nearly new residence sits on an oversized, premium lot and redefines modern coastal living. Large windows frame island views throughout, filling the home with natural light and blurring the line between indoor and outdoor space.
