There are different kinds of ivy and plant privacy screens that can be purchased which might cover your fence and gate and give you the privacy you are looking for. I have not used them before but the photos look very nice. If you picked a color to match your side or front bushes, it would look very nice and becost effective as well. You have a beautiful home. Good luck and please post photos of the final.

Thanks for all the great ideas everyone and sorry I didn't explain the polycarbonate a bit better :) This is along the lines of what we'll be using... http://www.psp.co.nz/building-brands/corrugated-sheeting/suntuf-polycarbonate The area is an absolute sun trap and we're hoping to use it as an extension to our living space, especially on rainy days! I've just sent my husband out to get a few pots of different stains for is to try - darkest brown (cedar) and a lighter brown (rustic oak) both by Cabots + the black we already have. Hopefully we can decide between one of those! I probably should have mentioned we will have black aluminium pool fencing running along the top of the second retaining wall - so the real question is do we keep everything black (pool fencing, horizontal fence, retaining walls and pergola) or do we go with a dark (or even light) brown for the pergola and retaining walls.... We just keep going around in circles at the moment. Decisions, decisions! Thanks again :)

value to you or value when you put your house on the market? it depends on the project. yes, a well maintained driveway and tidy yard will *help* sell a property. elaborate/hard to maintain landscaping won't. many people actually will think 'wow that will take forever/cost a fortune to keep looking like that.' i think more people want easy care as their first priority, and wont pay any extra for an overdone yard. so these days, i'd go all minimalist for resale value. small grass area with automatic sprinklers in areas where expected rainfall will support it, more stone mulch and low water plants in areas that are dry. ticks are a problem and mosquitos as well, so a wildflower border needs to have a defined edge with grass/stone before sitting areas. the nice night lighting no one will ever see when you are selling your house unless its the sort that has its photos taken at night with all the lights on. we've just overhauled our pool area at our vacation home; our theory there is that we want the house to be at all times 100% ready to put up for sale when the day comes that its not fun to own any more. so that $25K won't improve the value of the home, it will keep the home saleable. and we'll get to enjoy it til then.

Thanks for the replies! My wife suggested we talk to a local real estate agent, so i think that is a good idea... just that Im not sure how helpful they are likely to be if we arent selling yet :) As for saving for our dream house, I dont disagree, however if doing this up nicely over the next ~5 years or so while we live here nets us some extra in the eventual sale, then that of course will help us as well. Interesting thing happened today actually. I got a knock on the door and one of the older neighbours asked if he could take some lemons from the tree. I of course said yes. Anyway he was telling me he had lived in the street for 40 years. I asked him if the house had always looked like this, and he said no that ~30 years ago the old old owner did a massive renovation and pulled off the timber and put up the bricks and gutted the inside of the house. Interesting stuff!
