Timandra knows best, I believe, and has the experience to back her up. My comment is not plant-related, however. You have a front facade of door after door, and nowhere to go, except a narrow horizontal path. How about some front terraces, where you can burst out of one of those front rooms onto a sunny sitting area to have your morning coffee with a neighbor. Why not leave some doors open or change to glass, so the front terrace becomes an outdoor room, and extention of the interior space. How about a pedestrian walk out to the street, or over to the pictured tree, evergreen and plant bed, where you could have a shady terrace. Enjoy the outdoors, don't let your family become nature-deprived, with all the electronics that occupy our kids lives these days. Get them unplugged and outside - you too! You have a wonderful opportunity to achieve great things. Analyze first, then plan.

If time and budget permit I would add horizontal screens (timber stain or charcoal/woodland grey) from the right pillar to the garage (hiding the down pipe) and from the left corner of the house (hiding the bins) Do basic landscaping, two narrow beds either side under the windows, bark mulch and simple plants e.g. Lomandra longifolia (a native low grassy dark green clumping plant) is common but easy spaced every 30 cm Valuers like safe and neutral schemes, so keep with the Woodland grey roof/fascia & Classic cream garage door and repeat this on the upper feature slats for now. Then add a warm complimentary colour for the front door, this is Dulux Rodham Then get a lush new plant for that pot too. If you keep it simple (KISS Principle) for now it will come together for sure :)

Perhaps check with your local council to see if they have a plant list. Many councils here in NSW do this to assist homeowners with choosing native Australian plants and some introduced plants that grow well and are in keeping with the area. Of course it depends on the look of your house and whether your landscaping plan will compliment that, or whether you want a manicured look, or a natural look, cottage garden look (e.g flowers and hedges) or a beachy look (e.g. if you have a pool) and so on. Fruit trees sometimes need a different aspect to other trees, so separating food trees from general foliage is something to consider. Oleanders are off the list in many parts of NSW too. We recently put a fence in similar to yours but it has been painted black as our house is modern. We've been advised on lomandra, banksia and grevilias and lili pillys for a native garden as we already have lemon scented gums and ironbarks on the property. If you consider the building style of your home, and the trees common to the area you're in, sometimes that can give some inspiration

I don't know why people keep referring to these fad-driven green walls as sustainable - they are not. Green walls are completely unsustainable, when you consider what sustainabity really means. They are nothing but a Frenchman's idea that he pushed heavily to the landscaping industry that is now being touted as an environmental solution to housing insulation. They are actually useless in areas of high heat, especially when accompanied by high wind and low humidity. Most cities in Australia are not suitable because buildings are too exposed to the elements. Trees are actually required to increase shade to the buildings and the walls, and to increase evapotranspiration - hence the green walls are entirely useless. Of course they will cause fires when the plants die - they are entirely unnatural and won't last.
