Finding dry land

Named Shipwreck House for “evok(ing) images of a ship grounded along the shore,” this three-bedroom, four-bathroom, eco-friendly $2.9 million home nestled on a mountainside in Newcastle, California, attracts those who embrace green technology. An undulating roof collects rainwater in tanks that hold up to 12,000 gallons, and the home’s solar panels are connected to the grid and sell power back to PG&E on sunny days.

A bargain mansion
