Hi DR, unfortunately, I can't help you as this isn't a project we worked on so. You may want to reach out to the project's architect (https://www.houzz.com/pro/aidlindarling/aidlin-darling-design-llp) to see if they know or if not, perhaps they can point you to the landscape designer. (I'm not sure why your question was directed our way, the photo should be linked to Aidlin Darling Design's profile...very odd!)
