I really don't like the idea of cutting down established trees and shrubs BUT I understand your problem. Bear in mind when those trees are gone the front of your house will get allot more sunlight. I took 9 way over grown photinias out this spring. 3 were a hedge next to the sidewalk. they were taller than your cypress and had black spot so severely they dropped leaves constantly. My beds were always messy. Gone and I'm not missing them one bit. The other 6 were in front of my porch and had grown way to tall. They were too ungainly to reach and prune. Gone. don't miss them either but they did shade the hostas so I'll have to find homes for them. Good luck with your project.
