Front Garden Woes

For the last couple of years I've focused heavily on the back garden and have neglected the front. It's mainly because on one side, I share it with a neighbour. On the side that's 100% mine I'm going to make it a wildflower lawn but I have no idea what to do with the shared side. One of the problems is that I've had plants stolen from my front garden in the past so I can't have anything that's too "nickable". I'm also stumped about how to divide my and my neighbour's side. Anything that can be picked up/thrown/kicked is also a no go.
This is a photo of the front garden(old estate agent's photo as it's currently much too scruffy!). My bit is half of what's on the right so as you can see, I don't have a lot to work with. The tree that you can partially see on the right is a crab apple (don't think I've seen it grow much above 2m) and on my neighbour's side.

The garden is north facing and I'd also like low maintenance. I don't want too spend much either as I'd rather spend the money on my back garden as that's where I spend my time. It's not the easiest of wish lists, especially having to take the theft/vandalism element into account but any suggestions would be warmly welcomed.

I'd do the left side first and tackle the right side when funds and time allows
I'm not into topiary at all. They look great in formal gardens but they do need maintenance to keep their shape and I'd be no good at all at that. I'm pretty sure any smart looking shrub would disappear in the middle of the night the way my yucca did (hope the b******s got scratched to bits pulling it up).
I live in west central Scotland - not where that photo is...
It'd be nice if it'd work but if it doesn't I'll have to try to figure something else out. I just really don't want a plain lawn for the front garden.
Do away with any mither with maintenance and scumbag troubles.
Concentrate your love and energies into your rear garden.
@owd potter I'm not crazy about the idea of extending the drive. One of my neighbours opposite replaced their lawn with paving for better parking and it took A LOT of work despite it not even being very large. It's more money than I want to be spending on the front garden. There's also the possibility of having a porch in the future and I wouldn't want to do anything too permanent only to have to pull some of it up again.
