You're extremely unlikely to find 3 phase in a residential area.
Just make sure you have a 200 amp sevice (standard) and an electrical box with a huge area for adding more circuit breakers.
Tell the electrician you want a 60 amp welder here, a 50 amp air compressor there, and a 50 amp ? there, etc. Put in plenty, very hard to wire after sheetrock is up.
You'll end up running 3 phase equipment off a three phase motor/converter. You can build it yourself. My shop is the baesment and tuck under garage - sounds about like what you're doing. I only run one 3 phase machine at a time ( out of 8) off a 220 V 30 amp circuit.
