What a great space and big opportunity. Firstly, it looks as though your soil is fairly sandy and possibly hydrophobic soil - before you decide on actual plans start working at improving your soil so that you're setting yourself up for success (think about a good dose of organic matter, worm compost tea, organic aids like Natramin (a personal favourite of mine) that will help get your soil working with biodiversity, structure and creating a nutritional environment for plans and micro-organisms) and then think about going with natives as they're a bit hardier than cottage/tropical garden plants. Depending on your budget, you could pull out the fence all together or paint it a lighter colour. You could add a fence opening for pedestrian access further towards the middle and wind your path with steppers and gain a bit of privacy with arbours covered in climbing vines,. Don't hold back in putting in low growing plants in front of your fence either if you like (afterall your council ensure that you're responsible for it's maintenance). You could also soften the edge of the driveway using curving edging - taking away the harshness of the straight lines. I'd also look at doing something tall along the fence to balance the pencil pines on the driveway edge. Good luck!

I don't mind maintenance as long as I'm not pruning all the time. Budget wise probably no more than $1000 though I have no idea how much plants cost. I know hedging plants need to be spaced fairly closely. That's a good point about the formal hedge georgi02. I do love formal hedges though.

Thank you, you cant see the the trees I have in the photos due to winter but I have 12 trees already in my front yard. ( 7 silver birch, 1 mop top 2 weepings, 1 red maple and a another) I do love the hedging. I was thinking something like the below photo with the same path going to my front door but placing the same purple plants around the sides that I have in my 3rd photo . I would like to use edging do I place some along the 3rd photo. I love the above photo with the trees and hedge layering, I could do that along the front fence. What do you think ? I don't really know plant names so I am saying sorry in advance

Your site is far too exposed for Maples. They are small trees that really need to be buffered from winds and too much sun by other plantings. They also need the soil constantly moist which will be nearly impossible on that slope. You really don't want to grow magnolias anywhere near the footings of a house. Have you seen how large a tree they are? Since you are in a temperate zone and like autumn foliage I can recommend a gingko tree. It will be right sized for your yard and give you that similar lighter than air look and autumn colour as maples but it's more hardy. Another option are silver birches. I would hedge the boundary for privacy and also to cut down winds to your garden which will dry out the grass and scorch it. With that slope you are going to need more rocks I think to prevent your topsoil from washing away in the first rain. It's really no use of us to provide you a list of random plants. What you need to do is put together a series of photo's of gardens you like the look of, then find plants to match that style. If you don't plan gardens then you end up with the ubiquitous suburban patch of grass and odd bushes look instead of a lovely garden.
