Hello Mrs TJ,
Buxus will grow in north-east facing situations. It makes a good hedge because it's so adaptable and is an excellent choice for pots framing a front door. It does not take being buffeted by strong winds as it can become scorched, but hopefully your front door is in a reasonably sheltered position. Have a look at Monty's video on planting box at:

There is a lot of advice there about box in general which will be relevant even if you're growing it in pots.
Do send us a photo when they're in place!
