Awesome home! I would love to help build something like that.
I wonder what the price difference would be between designing and
building it from scratch vs. the cost of the center bearing and support
structure of one of the big rotating cranes running on rails around the
Those cranes are rated at 120,000 lbs according to the sign posted on
them. I doubt my current 1100 sq.ft. house weighs 60 tons.

Disassembly and precise reassembly would cost. One would have to run a cost
analysis to see which was better. Crane time to just unload and set it
would be a couple of grand, depending on the weight. The video states the
weight of the house and components, but I don't recall it. All that special
piping and wiring in the center that rotates could become spendy, but it
looks like the guy is particular about things and had a lot of money, cause
it's all first cabin. One could probably save some dough with lesser

I watched the movie again. Stated specs:
- 50 ton house (100,000 pounds)
- 32 support wheels rated 5 tons each (150 ton rated capacity total)
- 2x 500 watt (2/3rd hp) drive motors
- 360 degrees in 30 minutes
- 720 degrees max rotation, they limit it to 360 degrees in practice
- the center pivot bearing sure looked like the main swivel bearing from
a moderate sized excavator
- limiting the rotation angle means they can have all utilities done
with flexible lines supported in a tall central utility chase. Power
wire is no big deal, ditto for phone, data, water. Sewer line tends to
be shorter but still doable. Not so sure I'm happy with flexing the gas
- Weight number seems about right: those look like 14" or 16" steel
beams with 6" or 8" steel purloins
- I'd estimate one of the exposed house sides at 20' So an octagon would
be 1200 square feet. That looks about right.
- Each of the 8 radial beams would be about 30' long, perhaps 14x68 so
8 tons for those, another 5 tons for the circumferential beams under the
rim of the house plus another few tons of steel for the purloins. Sounds
like 20 tons of steel in the house deck, another 5 tons for the fixed
- Must have some nasty footings under the support ring. That ring has to
be set level and flat within the flex range of the wheels so I'd target
in the +/- 1/16" to +/- 1/8" range.

Rough estimate for stick framed house is 10-15 pounds per square foot

It's good. However - saw maybe even better on "Eurotrash" a few years
This bloke (in Belgium?) had bought a plot of land and converted the
base of a large excavator into the "foundation" of a 2-storey house.
So not only did it rotate but it could also relocate around the plot
as fancy took.
An earnest engineer or technical worker, apparently his wife had left
him, his current lady friend who was very happy worked as a stripper
or something like that and he explained that when he was building it
sometimes even he suffered doubts as to his own sanity (how many of us
have been visited by that sentiment... (maybe it's proof you are
living your life right if that has happened to you?))
