@ EMILY! Thanks so much for showing us all that you've accomplished...what a big...ongoing job and its not cheap undertaking something like that. Thanks for the tip about the star jasmine...I have a beautiful planting of that.....or rather 'had'...I got a chap in to trim it for me who advertised himself as experienced....Oh Dear! He killed most of the vine by cutting it at ground level! Now its a brown horrible mess up a tall trellis and no privacy. I'm devastated. To make it worse the neighbour sits out on her back deck and calls out to me when I'm out there when before she couldn't see me.....I'm putting up atemporary reed screen...I think....would rather my star jasmine with the blackbirds nesting in it....I know the feeling of not jumping in in case one makes a regrettable mistake. I also had gardenias but once they get sick its not worth all the trouble. I've had to learn heaps about what plants are appropriate for my place and I've made some really silly mistakes too. I've never seen those cut laser panels before and am a bit intrigued. What are they used for,,outdoor lighting? That colourbond fence works really well as a privacy screen! You've done so much and have invested not only your hard-earned money but also your ideas! Hope you have some lovely times in your space.

Thank you all for your comments. Well, it's been a few months since my original post and we have since finished putting up the retaining wall and planting the hedge. We decided to go ahead with Murrayas - planted about 34-40 cm apart. I gave them a good trim about a week after planting at the end of Autumn and another quick trim at the start of Spring. They have really filled out in warm weather and I think the gaps between individual plants should close by the start of winter. I'm really happy with the choice - the hedge looks glossy and lush and the sweet smell of Murraya flowers is just beautiful. We didn't do any underplanting, but I'm still thinking about putting in the dwarf agapanthus for the inside border. A couple of weeks ago we planted some Rhaphiolepis "Snow Maiden" and Rhoeo along one side of the retaining wall to provide a border for a footpath and I'm really happy how it turned out.

Is it privacy or weather control you most want? A custom made long blind might work well for the long window, if you want both privacy and heat/cold control. You might also think of external solutions, including plantings that would manage both sun and privacy for the lower levels. Having something that cuts neighbours views and gives you a nice view is always a good solution, and can be an important part both of privacy and weather management. A front courtyard of any sort (built wall, plant wall) also works well - we had one at an earlier house and it worked well. We had, in our just moved into place, a long window beside the front door, which also gets late afternoon sun (hot at present), and I replace the two panes with a stained glass pair of windows and it cuts the sun and increases the privacy, but it's not a cheap solution when you have such a long window.

Always check with your council, they mostly like to get cars off the street in the city if the can. It is a great looking house and will be made to look even better when the car yard can be moved to the R/H dead side of your house. Don't do something because it's the cheapest, have a plan and wait until you do have a few spare dollars. It will add big value to your property With 4 cars it looks like you could call on some family man power to do some of the work, and if you have family or friends with trades required to do the job, throw a BBQ but no food or Beers until the works done cheers
