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.

I've done that with an old old weatherboard...very small house. Did a semi enclosed elevated deck...as the house is on piers..slatted a-la-old Queenslander and partially enclosed with transparent roofing against the wind. The roof is colourbond interspersed with transparent corrugated panels. Have vines growing in through the slats from a garden bed near the front entry....maked for a lovely indoor-outdoor space with many uses. The vine I have is a very old plant calle Podranea...twice a year produces lilac blooms and is evergreen. Requires maintenance as is very vigourous. the rooms along the northern side of the house all open out on to this lovely indoor/outdoor space. Have a lovely fountain as well as hanging baskets. This space has opened up the whole house and protects both in summera and winter. It has made a difference to the whole ambience...so good idea....most probably your venture will involve a more modern aopproach,,,I tried to keep the "old house" image. An indoor.outdoor room is the best improvement in my opinion. Could not do without mine.

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!
