At 75 feet long, this new take on the classic houseboat boasts 4,350 square feet of living space and is able to float freely, be tied to a dock or stand up in the water courtesy of hydraulic legs. The home features floor-to-ceiling glass walls to allow for unobstructed ocean views, five bedrooms and a rooftop with 2,300 square feet of solar panels. Pricing starts at $5.5 million, though it’s also currently available to rent for $6,000 a night.
