Wow! What a beautiful home :-) It's got lovely clean lines, but these can also look a bit stark, can't they? Have you considered Espalier or something similar against the walls between the garage doors, etc.? That would add some softness and colour (as well as fresh fruit!). For the front garden, you've really got a lot of choice for such a lovely aspect. If you were after a more 'finished' look, then perhaps consider a front (picket) fence with smaller natives and a bigger grevillea or similar as a feature. For privacy, perhaps a hedge of lillypilly. Or for a more formal look, landscape with sandstone to create tiered beds and plant out with smaller natives, lavender a herb garden or a mixture of all three. Enjoy!

I've heard that Ponga Fences' will thrive in shady conditions, but if you put them in the sun, you have to water it every few days for a few months so that the roots take hold. I hope you ended up doing it and your Ponga Fence is thriving!

Looks like the palm tree look is working so I would blend that with some succulents maybe agave which can grow large and make great statement plants. Also stick with the stones.

Ouch, Lancewood! Nice read, FORM :)
