My main garden is out in the boonies too, and if I couldn't keep the deer out, it wouldn't be worth the effort. For me, the best answer was T-posts, and an electric fence. The posts are 7 1/2 feet long, driven in every 10 feet. The same posts do double duty for my trellises, one of which (with Bitter Melon) you can see behind the fence. They are very easy to install, with no digging, if you buy or borrow a fence pole driver. The wires are only about 5 feet high, but if I get the fence up early (I take 2 sides down in Fall for tilling), the deer get bit once & never try again. If a bold deer figures out it can jump the fence (which occasionally happens) then I run a string across the tops of the poles, hang flags & pie tins from it, and the deer seldom tries again. The electric keeps raccoons out of my corn, too, and seems to be effective against wood chucks. Had to modify the setup a little, after rabbits (actually, one really fat rabbit) completely destroyed several crops. They just hop between the wires. So now there is 24" of rabbit fence on the bottom. At home, I used metal fencing, instead of the electric... again with 24" of rabbit fence at the base.

Love these images of your garden. What are the dimensions? I'm trying to turn a 14'x21'patch of lawn into a Japanese style garden. Your pix makes me think enclosing it might be a good idea. Would like input from someone who's created one. If you'd be willing to give some advice, I can send 'before' photos.

My house is those typically light red or dark pink bricks with white trims. We replaced all the windows so they are of vinyl white.

Someone in my former neighborhood had a solid fence that was covered in stucco, not stone. I think the cladding choice would depend on the style of your house, but I wouldn't go any higher than 6'. I don't know how much noise abatement that will result in either, so maybe you should keep your expectations reasonable. It may not make enough of a difference to be worthwhile although it would definitely make a difference in terms of reducing sightlines. I second the comment about having your lot line surveyed first. We replaced an existing fence on a property when it was old, putting it exactly where the old one had been. Right when we listed our house our next door neighbors decided they wanted to change the placement of their driveway and had the lot line surveyed. We then found out our fence did not follow the lot line and it caused turmoil around the settlement with the people who bought our house. If all parties hadn't been reasonable the sale would probably have fallen through.
