You can run most single-phase equipment on 3-phase.
I believe 3P is 416V there. That means there are 3, 220V phases. So you can run anything 220V off a single phase.
You can also run single-phase equipment across 2-phases. Then you would need to configure them for 416V.

If it is next door then it will be in the jointing chamber outside. So relatively easy to bring in, TBH I'm surprised that it's not already there, it's fairly normal with most industrial units.
The industrial rates on 3ph are a bit cheaper, but you have to be using enough for it to kick in. At work we manage to get about 10 - 13 days of the lower rate that's with about 3000 light fittings running all day!

You can have all three mate..
If you mean, can you have single phase and 3 phase... then, yes, as single phase is using one of those three to neutral (240v). Or you can use two phases to each other (415v, as used by some welding sets), or 3 phases (415v), as used by standard 3 phase equipment)
Just hang off your 240 equipment from a phase and the neutral. Try and arrange it so that some equipment draws from each of the phases so you dont load up that phase too much with respect to the others. For instance, here my garage and outdoor stuff is on P2, the workshop loads P3 and the house runs on P1 (yes I have 3 phase to my house). Theres also a seperate 3 phase feed to each zone since they all have 3 phase kit in them (the house has a 3 phase immersion heater!). I also run my 240 spurs into different consumer units than the 3 phase stuff, to try and minimize the risk of wiring mistakes.
Then into the safety aspect, do NOT wire equipment near to each other onto different phases! if you have a fault you can get a cross phase 415v shock instead of a 240 one as a result, and the chances of ending up dead are greater. I'd imagine that business use dictates the use of a qualified spark to do anything like that, and they should know that stuff off the top of their heads...
Having said that, ive seen datacentres wired with every alternate cabinet wired to the next phase, and in fact they were touching in places, so even "proper" electrictians get it wrong occasionally...
