Privacy Hedges?

Privacy Hedges?

My boyfriend moved into a house, last year. After a ton of hurdles, we were finally able to move out of our apartment! That apartment was so tiny, too. Anyway, we now have an issue with our neighbors. While they are sweet old men, they are always on their back porch. Our back patio and their porch is nearly side by side, so we don't really have any kind of privacy when we are outside. My boyfriend came up with the idea of a lattice screen on our side but I don't particularly like that idea. I would like to plant something there that will be easier on the eyes. The problem? We have about 3' to work with. Also, we couldn't plant anything with deep/invasive roots that could tear up the patio tile/concrete. Ideally, the plants would be a minimum of 5' tall. Lastly, we will still need about 1-2' of space to walk through so we can get to the side gate, water meter and such. Is this even possible? Is a lattice screen the only alternative? I very much a novice gardener and I have looked at different plants but I would like to get some opinions from you guys! ETA: We are in zone 7-8
