Epic

RV's costing over $1 million, including a high-tech mobile mansion with a man-cave.

Imagine talking to your home using voice commands and having it reply or a home which protects you from intruders using dangerous gadgets straight out of a James Bond movie. Another home allows you to change the size of the rooms themselves or even the exterior color of the house.

From toilet lids which open as you approach to to self-setting temperature and pressure showers, bathrooms are getting smart. If that isn't epic enough, how about a bathroom with indoor rock formations, a fireplace, and even a waterfall? These bathrooms would be the envy of royalty.

Replica of Fenway Park; swim-through caves with bars; courts big enough for the NBA; tennis court over a cliff

Living close enough to the ocean that you can listen to the sound of whales and dolphins. Glass doors big enough for a hangar; windows, windows everywhere; giant master suites. These beach homes are so epic that even Kim Kardashian lived in one.

Right here in America you can find turrets and gargoyles or dungeons and moats. Bowling alleys, giant spas, and a car elevator, these castles have it all.

Island in the marshes of Georgia; remote Montana mountains; automated boat docking system; shooting ranges; helipads.

These are not the log cabins American pioneers were building. These are enormous homes of determined individuals, making their dreams become reality. Casinos, gyms, and game rooms are the norm around these parts. The green of the Midwest; an active volcano in the Pacific North; the Colorado Rockies; a mountain top perch overlooking the Vegas strip.

Lincoln Logs only get you so far. These people are building sprawling, multi-million dollar log mansions. Multi-story fireplaces; fully-stocked bars; movie theaters; game rooms.

Einstein or Frankenstein? That's what you may ask yourself about the builders (and the owners) when you see these engineering marvels. Side of a cliff; inflated underground domes; converted sunken shipwreck; world's tallest treehouse; flying saucer that actually spins.
