Unless you're lucky, the neighbors aren't going to put great looking plants where they will enhance your views out of your windows. Or you might not have a neighbor close enough for that to be an option.
I've done some things to improve the view from various windows, but have now cleaned out what used to be a play room to make an office. And now I see that I have more work to do because this view isn't what it could be. My work bench is in the way, blocking the view of some of my fav spots. And I need to clean the window!
Are you planning/planting views for yourself?
