What's special

The Island House in Caspar, California. Likely the most rare and unique coastal home ever developed on the Mendocino Coast. The property is surrounded by the Sea on a Bluff above the water and connected to the mainland by an Iron Bridge. Built in circa 2018 this 1,709+- sqft, 1 bed, 2 bath coastal development marvel has gleaned the eye of sailors and captains since its inception. The residence is anchored in bedrock and offers a spacious wine cellar/basement and all of the modern high-end luxury touches that one would expect when surrounded by glass, rock and water. Rarely can one look back towards the safety of land from their home and see the radiant beam of a light house. This is a once in a lifetime opportunity to own and live on your own California Island!
