I like the bricks in the fence and you don't want to paint or render this, as you would be providing a lovely, fresh canvas for graffiti 'artists' to scribble on your walls. However, you could create a border area just in front of the fence and plant some shrubs or narrow trees. (Just saw a segment on Catalyst on the ABC the other day on types of trees which help to filter out pollution from your home. Silver birch trees seemed to do well, whilst taking up very little space and being quite sparse.) Even a border of mondo grass would be good, though this is very short in height.

Jacey, nice to see you are still here, many aren't after this length of time. I'm having a little chuckle here as when I originally read your post, my first thought was "move house", but I didn't want to sound so rude as to say so. It reminded me of my first house which was at the flat end of the street but the other end was very much "mountain goat territory" and the driveways reminded me of yours. After living in the homes for years, some spent mega amounts removing rock and excavating to create a garage more at road level and from there the stairs started zig-zagging to the front entry, new front entries were even created at a lower level, but the stairs still continued inside the house, there was just no escaping the climb. I wondered how you even got your wheelie bins up and down the drive. Hope you are enjoying your new home, long term I think you made a very wise decision.

You've got a good space and good ideas. My suggestion would be to decide on all the structural changes first. It is tempting to go for small wins first. But you'll never regret doing a master plan. Set out everything you want to do. It's OK to have lots of stages and even a few dream things.

It always makes my heart sink when a client asks for a "no-maintenance" garden. It tells me they really don't care. In truth, any planting needs a certain amount of care. Plants, like animals, need care. It's true that they're slower than animals to respond to deprivation, but respond they do. And it's not a good look. You might not have a lot of time, or you may not be physically up to a lot of gardening. That's fine - you can choose plants that require a minimum of care and grooming, and if need be hire somebody to do that minimum. But it does require planning. A gardener actively engaged with their garden can (and will!) experiment, try new things, move plants around, notice when things are going right and wrong, and for them a garden is never finished. Contrast that with somebody who wants a garden they don't want to work in or at. They want a garden that is more or less "finished" the day it is installed, rolled out like a stretch of lawn and meant to "behave", to stay static. I can't do a garden like that! Plants grow! They change, the environment around them can change, and what might have succeeded one year is not going to do it the next. It is entirely usual for a planting that just nicely fits a situation to need complete re-planting a few years on because the individual plants have outgrown the site. That's work! It is entirely usual for plants to flower, and for those flowers to set seed and die off. It is entirely usual for some plants to shed leaves as part of their yearly cycle. This "mess" is treated by non-gardeners as a crisis, as a nasty surprise, as something the plants "shouldn't" do. Because it makes work. Well, sorry, but no garden consultant can change the laws of nature. If you want a garden, you've bought work, and if you don't want to do it, you're going to need to pay somebody else. That's fine. Just don't ask for what you can't have.
