This UFO model is actually a floating home. Known as ‘UFO 2‘.
It is a concept for a three level houseboat. Each model has a full amenities, including a hot tub and a submerged bedroom with an underwater view.

Look at its design plan and structure:

The home would move at 10 miles per hour using twin engines. And run on 100% solar and wind power. The creators improved this concept after announcing it earlier this year.

And plan to ship initial models in 2018 refining the term UFO as Unidentified Floating Objects.
