Evergreen Broad Leaf Trees for screening

I was wondering if you could suggest some attractive trees (at least 10ft tall but not necessarily too wide) to provide screening along a south westerly facing side wall in my suburban garden. I would like evergreen trees so that the screening is year round but I don’t particularly like conifers but I cant come up with anything on the plant finder or elsewhere. I saw something that I like, that looked like olive trees at about 12ft tall but I wasn’t sure if they would be hardy enough to grow so well in Ireland. We lost a lot of shrubs last winter so whatever we plant will need to be quite hardy.
