I am measuring with my eyes and a rough building footprint which may not be to scale. I couldn't fit the doors into my guideline grid on this one. So I drew the doors separately and will merge it all together in proportion with Photoshop - in addition to all the corrections indicated by my pencil lines and arrows.
This building is the END of the BLOCK. Next step is to scan all the drawings for this block and string together the streetscape.
I will take some measurements on the next block I draw.
