Welcome Annette! I am your neighbor, relatively speaking, over here in Durham. We also worked with a designer, Adriana Chanmala at Earthius designs. She was great and we are very happy with her design. What designer are you working with? It was so hard to find one.
Also, have you heard of Dr. Will Hooker? He is in Raleigh, but I don't know if he is doing anything anymore. His website,
https://www.610kirby-permaculture.org/ seems to be gathering dust. But it would be cool to get a garden designed by him.
