A local garden store or designer will certainly be able to help you. In the meantime, you can look up ideas online, but you'll need to know some basic information before anyone can help you choose specific plants. The first and most important is to know your planting zone, which is all about your location and climate. You also need to know the directional orientation of your house and the wall, and whether it is "full sun", "partial sun", or "shade". Will you be planting on both sides of the wall? You may wind up with vastly different plants if one side gets full sun and the other is in the shade. Take into consideration whatever shade is cast by the large tree, and the house itself. If you have the time, spend a day taking pictures of both sides of the wall - maybe once an hour (shadows will shift somewhat throughout the season), so you may want to do this every few weeks and keep a visual log of how the shadows move. Also, before you plant, decide if you want to paint the wall. It will be easier to paint before you plant, of course. White will reflect heat back onto plants. Climbing plants would look nice on the wall, if you're not going with a very structured garden. Ivy is an obvious choice, but there are other vines that flower beautifully, if you like that idea.

And I would be planting trees – real trees not dwarf versions of trees and no more palms (unless you want to have palm tree themed garden – in which case a lot more palms are needed). I am not advocating planting forest giants but there are trees that will provide shade, shelter and a sense of scale that you won't get from yuccas and buxus and mondo grass and succulents alone. But before you start buying those trees you have a few decisions to make and a bit of analysis to do. 1. Orientation – you need to understand the basics of winter sun and summer sun, how much westerly sun you welcome and how much you need to shelter from it; where your prevailing winds blow from and whether this changes with the season also. So, once you've worked out where you want the sun to penetrate and at what time of the year, how to allow for wind, frost, whatever... you need to 2. Decide if you want a predominantly native garden, a range of deciduous trees or a completely eclectic selection (like the best 'English' gardens – which are planted out with plants from all over the world – Indian subcontinent, Asia, Africa, The Americas etc. Even some from Australia!). 3. Now the tricky bit – what do you love, i.e. which trees and plants make your heart really sing – and hopefully for more than two or three weeks of the year? Once you have that list which of those are likely to be happy in your climate, in your soil and with the amount of gardening attention (watering, feeding, pruning etc) that you're likely to enjoy lavishing on them. Your long list will by now be a much shorter (and more manageable list) but trees are what make a house look bedded in and part of a landscape rather than just sitting out in the open in a way that is both self-conscious and a bit awkward. Although, again I guess you could embrace the suburban awkwardness and go all Howard Arkley in which case keep it all small and suburban... But it is your garden and your house – make it look like what you want your house and garden to look and feel like! Good luck!

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!

windows in master bedroom need to allow views and privacy and much as i would prefer bed on NE this keeps the bed in view towards and from family room so prefer bed on south wests wall and small sliding doors pushed towards north side of room with tall narrow window beside sliding door and highlight window for light with privacy and wall space for chest of drawers...acknowledging theta the pwdr doesn't have a window but my suggested arrangement uses less total space more efficiently and is better for older kids and long stay visiting parents (more people can use the various options at the same time) and a small ventilating skylight will exhaust and brighten the toilet and vanity area ...the wide door into the lounge can be a stacker or stable door so you need to investigate local options (and everything is expensive unless it does what you want...we always use solid core doors that can be ten times the price of a basic hollow core door but love them so we economise elsewhere) and barn door between entry and family would be OK as long as you like them and it doesn't compromise lounge doors but could look ok if both doors are the same style and different widths...and location of dishwasher is personal and if you have already been unhappy with sink in main kitchen then have it in the scullery...main advantage of my suggested kitchen location is that it's closer to the front and the family area and external doors and the pantry uses the central space that can be much better illuminated with another ventilating skylight instead of a tiny external window and noisy exhaust fan
