I have one more question, I hope you don't mind. When waiting for the landscape, we use windchime. The opposite house was newly built,when that house was still in frame phase, we observed the roof line and know that the line points directly to the window next toour maindoor. The window is also important to us, it's the study room and our children spend 4, 5 hours in that room everyday. Can we place the windchime to protect the window instead of the door? Thank you again, and sorry for so many questions.
