Ozbern: we had a similar dilemma, lovely backyard and then they started tearing down bungalows and building four story townhouses all around us. I built a single depth pergola along the back property line, the beauty of this is not only the privacy, but it brings the scale of the yard down to make it feel more intimate when we are outside. We also added a 10' x 10' (little over three meters) pergola right up against the house where we had a wall of windows. Will try to find that photo too. We have coral vine now growing in it. Dies in winter, comes back in spring. You can always do more contemporary details if this is too casual.

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.

My ex-husband and I had an issue with a large window that looked out over a sidewalk where people were constantly walking by and looking directly into our living room. We solved the problem by using window film that was one-way so we could see out but it was like a mirror if anyone tried to look in. There are other varieties as well. We still got all the sunshine and light but didn't need to worry about whether or not the neighbors could see me watching tv in my nightie on a sick day...It also meant the door to door salesmen couldn't look in and see that I was home when I didn't answer the door. http://www.gilafilms.com/en/privacy-window-film.aspx#.VOuUBS5vksQ

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.
