I've never see a 3 phase in a house.
Quite some years ago my father inquired about getting
3 phase power to his house to power a rather husky lathe.
The answers were distributed between "impossible"
and "prohibitively expensive".
Phase converters are usually the answer for that sort of thing. Whether old electro-mechanical (rotary), or newer static inverter designs, there are solutions out there that will get the job done a lot cheaper than convincing the utility to run a three-
phase service drop to a residence.
Ironically, used three-phase equipment like lathes, milling machines, large band saws, planers, etc. are relatively 'cheap as chips' on the second-hand market.
I have a friend in the US, who has a large milling machine that takes
3-phase. He wired he 1st phase direct to the outlet, then the 2nd phase through a motor which just sits there spinning with nothing connected to
it. And I think from memory the 3rd phase isn't connected at all. This
is apparently enough to run the machine. The motor, not motor
generator, is just an AC motor, is enough to offset the phase that it
fools the machine into working. I may not have all the details correct,
if anyone is interested, shoot me a message offline and I'll chase him
down and get the details of what he did.
I think we're way off topic now...
