There is a lack of detail here that leaves me with questions. For example, I can't tell from your drawing how the lower unit tenant would access his door. The current entrance area would be blocked by the new position of the stairway.
It's also hard to tell how the awning is constructed, but I think the lack of exterior supports means it will have to be supported from within the structure, which seems like it would be expensive.
I don't care for the green bloc pavers because they require mowing, and I request low maintenance.
And painting the facade is not an option.
