Matteo - obelixx can you give you the best advice here, as she's in the same country! Her 'local' knowledge will be very helpful for you.
Most of us are based in Britain and even here, there are huge regional variations. I'm in central/west Scotland on a hill (about 500 feet above sea level) and my garden is fairly exposed. I've gardened on more exposed sites than that too, so I'm well acquainted with wind and the damage it can do.
It really comes down to the look you want as well. Shrubs will give you a good shelter belt as well as disguising that shed, and careful choices will mean you don't lose your lovely views. Once you have some shelter, you can plant a wider range of perennials, shrubs and so on, according to your own taste.
Good luck with it
