This poll is a bit silly. It depends on the installation. I do like the exposed plumbing, but then the concrete is hard to beat as well.

attaching the garage at the corner can be complicated for the roof so this also has to be considered but can you post a plan of the block showing the proposed location of the new house, distance to each boundary, the front gate and any existing driveway, arrows showing the direction of north and any views and is the block sloping in any direction or relatively flat? the problem with acreage is that there are so many choices and you probably also don't want a view of the driveway from the bath so we need more information about the block

You could try Wet & Forget on the driveway. You can buy it ready to use and attach it to a hose or buy a bottle that you dilute to use in a sprayer. I have used it and it works - slower than water blasting but it won’t damage driveway if it has some damage? I can’t quite tell from photo if that’s grass clippings/mulch or broken concrete on driveway? If you use it be careful not to spray garden bed. I live in FNQ and we planted seaside daisy - doesn’t need watering but it also won’t die from our wet season. It’s a ground over and spreads out beautifully in a courtyard area that’s get a lot of sun. Just needs a trim from time to time. I see you have Rio (purple green ground cover) which you could separate and plant down the path but it does like water. Maybe for the fence you could try attaching lattice to it and plant another passion fruit vine to help cover the whole fence. It does look like you need to get rid of some woody parts of the passion fruit. It’s a tough plant and will enjoy a bit of pruning. We had one that I thought had died last year and it has returned with no help from me. Be careful with the heliconias and gingers ... they can get out of control if you don’t stay on top of them. Anything tall will cover your fence but it will also cover the passionfruit vine which obviously loves the spot it’s in. Good luck!

lilypilys are lovely... I think some more lush green small trees and shrubs (there are plenty of native options) would help cool and soften the hard landscaping. Have you considered a small butterfly garden with a little path of steppers that wanders through? Your little one will love that as they get a little bit older. It will become a special little spot to wander and explore. I've converted my entire front lawn into a nature play space, the kids climb the lilypily and pick and eat the berries, they have a little cubby house they built under the front stairs. there are strappy grass plants and timber pathways that go across a 'creek' of river stones. the kids balance on the river stones and there's a big wooden log to climb. There is no lawn out here, and it seems to inspire a very different sort of play they watch the insects, and look for frogs and the flowers attract butterflies. stepped pavers mean hopping and jumping, wooden timber walkways help with balancing... all in all its still pretty safe though. plants flower regularly, there are bulbs that pop up and surprise the kids, and all the plants are rugged enough to withstand the occasional accidental falling into the garden. grasses that have silky tops, anything with berries and seeds and interesting seed pods things like lilypilys, a small area with river pebbles, the kids love playing with all of that, and lots of little bushes with small flowers that can be picked regularly and harvested into baskets. my favorite cheap and cheerful flowers include dogbane, nasturtiums, calendular, marigolds... herbs with interesting smells that can be crushed like rosemary, mint, lemonbalm. you can even make a safe fishpond in a tall pot... little guppies are fascinating to watch! And a bird bath would be nice. the back yard can be a more of a rowdy rough and tumble play area, but a little front yard can be a special place for wonder and exploring nature. Our front yard is really not a massive space but there's just enough to bring the butterflies and tiny birds and create an extra play option.
