Pete, if you're still planning on bamboo as a screen, I'd get some advice on it. Although I don't want to put you off, I've got some in my garden that I wish I hadn't planted now. Once it's got a hold, you've got it forever. A bit like rhubarb! I have to say it looks lovely, but I battle with it every year to keep it cut back so it doesn't take over. I've now confined it to one corner, but the runners spring up through the soil all along that border.
The cat loves it though, and she's often to be found snoozing in there in the summer.
I hope that helps.
