I see the artist architectural rendering. I read your comment above.
Please provide a reference point from which to locate your points:
"It appears that the rendering is very accurate and that those gray portions of the lower floor are stucco panels that will be used for graphics. The two openings on the right are the only ones for windows"
Lets try this again please so we understand the areas you are talking about.
Far left building look like white canvas window graphics.
Center building looks like clear glass windows with canvas text (can not read) graphics above.
Far right building looks like green canvas graphics "Pub..something" outside shows gray canvas umbrellas.
White pipe fence line
Asphalt walk way line
grass area line
river edge line
Hope you can help us understand the accuracy of the illustration.
