A few weeks ago I fitted some white plastic guttering to a large set of out buildings we'd been working on. I was a little dubious as we'd normally fit black guttering to something like this but I think it really looks good and matches in with the house.

It took just over a day to get it all up. I tend to fit guttering level as it looks a lot better than having a heavy fall and so long as it's done right then it will run from the outlets as soon as the rain starts.
