Trying to figure out exactly how to do the buildings, I tried this one which is fairly low res on the windows, but once you make the wall 144 feet long (my chosen base size) it has 48 windows per side per level. So one level x 4 sides is 192 windows multiplied by only ten stories is sill 1920 windows so the res of building zooms up fast. Since I wanted to do 100 stories, and that makes 19200 windows per building. I haven't created an entrance yet, need to go over Richards pics and see what I like for this one. May add some balconies too for the more detailed close-up buildings shown here. Why 144 feet? the block is 300 by 900 so dividing it into equal sections it makes it 150 feet per section making12 buildings per section (2x6). With the buildings being 144x144 it means there is a 6 foot wide alley between each building and a small 3 foot wide ground space before the 6 foot wide sidewalk. I may need to make the window a simple square and then paint the detail based on Richard's photos with no actual model detail. Maybe I will try this for the buildings in the distance and just use the full detail buildings about 3-5 stories high for close up renders from the sidewalk.
