Not really. Sister-C... My advice to you would be to start with plants that not only provide you with privacy but also start to build "rooms" where various gardening needs can be met... That means workin' the perimeters with evergreen and deciduous trees that will grow relatively quickly and start to enclose areas that will be yer future "rooms"... It sounds like you'd like to create a meditation garden so you might use similar trees between your house and where ever you'd like that to be which I would think would be the area furthermost away from car noises and neighbors...
It you use a backdrop of evergreens around the perimeter then you can work nut and fruit trees more toward the interior and closer to you house...
We use cryptomeria radican (google it) primarily for this purpose... It grows quickly, is disease resistant, has a good root system and provides a nice screen... I'm not sure if you have them in the UK but you oughtta be able to find a nursery that has something similar...
BTW, if you were to send me an over head sketch of your property I'd be more than happy to draw up a few ideas for ya...
But... "bones" first" and work yer way down from there...
