Perhaps if you look at your outdoor spaces as outdoor rooms, it may help you personalize and organize the areas. What I see in the photo is a small front yard divided in half, and a tree placed exactly in the center of the other half, within a little square of bed. I expect you would not do that with an interior room. A visitor will be compelled to race down the hallway to the front door, and probably not even notice the tree, since it is not part of a composition, a furniture grouping. You enter your living room to a welcoming composition of a furniture grouping, lamps, pictures on the wall, drapes (I hope) on the windows. You get the idea. Would you put a post lamp in the middle of an empty room? It would tend to diminish the size of the space and it's usefulness as a space. Would you put a carpet down the center of a room? -- only if you were creating two separate scenarios of equal size. You need some on-site advisers, whether they be landscape architects or interior designers, someone or more than one who will offer their experienced suggestions for you to consider, but not immediately act upon. You need to live with your new spaces and walk through their ideas for weeks, or months, before making a decision on how to proceed. Perhaps it would help you to read the thoughts of some international designers like Bunny Williams, with her book, On Garden Style, where you will get the feeling that the views of the outside rooms from within the house are as important as the views from the street. You will want to move the maple out of its central location, remove the central path, - and the conifers scare me. You really have a very small space up front here. Take a look in the park at the size of a mature conifer. They will occupy your yard and that of your neighbor, as they develop as nature intended. They are very beautiful, a work of art, but space-consuming. You may have room in the back yard, but be careful when blocking the magnificent views from within the house. Perhaps you will provide an entrance to your outdoor room over to the right, near your property line, with the tree, the lamp post, a small chair or bench, a bed of small plants that have beauty and fragrance throughout the seasons - a space you would like to sit in yourself, perhaps have coffee with the neighbor, or the kids hang out with a pal. Then have the walk work its way over toward the entrance area - not the door, but the welcoming area before the door, slow them down to enjoy the sequence, while providing a most pleasant view of this area from within. Make the plantings permanent, with no soil or mulch to show, after two years, as the groundcover plants mature and cover the beds. Keep all the annual plants in containers, to be stored away if empty, so the views of your spaces are not distracted by an open area in the bed where the annuals have departed, or an empty pot. Consider excluding your auto from your outdoor room, your welcoming area. You don't have room for a real screen, so just a suggestion, as a small hedge or plant bed to stop the eye before it gets to the drive. Perhaps the view beyond the drive is attractive, so all you need to filter from the view is the driveway pavement itself, as the car belongs in the garage, yes? Sometimes a little perimeter fence with a gate says welcome to my special space. In your case perhaps a darker color, not the typical white, which would be a high contrast to the house and not appropriate here, grabbing all the attention. What I have offered may be of no use to you, however, the intent of my words is to provoke you to analyze first, then plan. Consider alternatives from all viewpoints before deciding how to proceed, as these spaces and plants will be a part of your life for many years. Good luck to you. Continue the process at the tortoise pace, not the hare.

As your house is a lovely grey I would consider plants which harmonise with that shade. So consider a range of grey leafed plants such as olive trees (these look great at night as the leaves have a silver backing), wattles, feijoa, euphorbia, lambs ears - an interesting textured ground cover, as is snow in summer. Then a striking deciduous coloured tree or large shrub such as a maple with red leaves, smoke bush, or crepe myrtle. There is no need to build a fence unless you really want significant privacy, shrubs do provide adequate separation. As the home is tall and quite imposing I would also plant three pencil pines neat the front of the building, these will soften the edges of the building and help it relate to the garden. Most grey leaved plants are very hardy. wind may prove more of an issue than sun or soil, I recommend that you look for plants at are labeled 'suitable for seaside locations'.

coming from a northern country to Australia, I miss the white Christmases. A white decorated theme makes me feel at home and brings back happy memories whilst experiencing a non-traditional hot Christmas.

Call up your local landscaper. It's not usually the price of the rock but the price of the equipment used to put them into place. Rocks that large can't be manually handled. You'll need some kind of hydraulic crane. If you are lucky the landscaper can reverse their truck directly into your backyard and use the one attached to their truck. If you are unlucky, you'll have to hire a separate piece of equipment.
