Yep, they used to wire the hot water cylinder & 1/2 the stove ( or all of it ) to one phase ( say Red ) and everything else to Blue. Next doors would get a Blue hotwater cylinder & oven, and the rest of the house was White. While the next house got White hot water & stove & everything else is Red.
That way, over 3 houses there would be a average drawing of electricity over all three phases, in theory. But, if somebody wasn't home at one house, since it was done like this down the whole street, it did average out by the time you measure it at the transformer.

And my old street has exactly this system as well. Late 60s, underground cables from new.
New (to me) house already has 2 phase. And there are overhead wires in the street, as well as overhead to the house. Will be far easier to get it upgraded to 3 phase.

Incorrect. When I built my house back in 05, my sparky said I would need 2 phases as it was large and a single phase probably wouldnt cope with the load. Several of the homes our company build have 2 phases for the same reason.

even if you have all 3 phases running past your house thats doesn't mean you can get it. all depends on loading and how they have done the equalizing of loads. only power co will know if you can or not.
