The four story house is surrounded by pool on all sides to give the illusion of an underwater kingdom. The windows on the inside are arches so it appears like there is nothing between the inside and the watery outside (almost as if the inside of the castle has water inside it as well?) The ocean floor is covered in wreckage of sunken ships and crashed airplanes. Hidden treasures, monsters, and the ruins of a former civilization. #underwater #sea #underwaterhome #kingdom #castle
