Privacy hedge in large planter

I am looking to put some type of privacy bush / bamboo along the inside of my wood fence since my neighbor decided to build a tall lean-to next to my fence to store his 4 wheelers under. It looks trashy and I would like to hide this from my view. Problem is i have brick pavers there so i am looking to do a potted type plant / bush that will block this view. I would like something that is not messy and won't drop foliage into my pool. Possibly will use a galvanized tough of some sort as a pot. Thanks

I know get better neighbors, That's not an option at the moment
