This is actually more of a house ship than it is a house boat. It was built by a Russian guy Nicolai without any plans or sketches. His neighbors call his house: Nicaloi's ark. It is 9 meters high and 14 meters long.
Although it is rather unusual, it has all the comforts of home. There are even sauna and swimming pool on the first floor. In addition, this family is ready for another flood.

People have always had a love of the water, and these ten houseboats show us exactly how crazy people can get when they design a houseboat for fun and pleasure.

Submarine

This guy decided to have a sub house, but hey it is a water going vessel.
