Day 2 done!
Damn am I looking forward to this coming together. Built another – admittedly more simplistic – building along with a path and a few pieces of clutter:

Pro tip: if you’re gonna be duplicating a lot of geometrically identical objects then use Alt+D as opposed to Shift+D, this does two things:
A – Makes it so that editing one edits them all, so if you add a material or move vertices in edit mode it’ll affect them all (though do note object mode geometry manipulation only affects that specific one).
B – Decreases memory used, which will allow your viewport to run faster (if/when it starts to get hectic) and for your scene to render quicker.
Looking at it longer the second building looks considerably more bare than the other, I definitely intend to improve that. Gonna be uploading the file when I’m done so y’all can have a poke around if you are so well inclined, but for now that’s a day!
