L1:
No visual control of Lobby, GR and CR
TS / MP direct access not required, they just need to be "close" (swapped TS with LRs)
L2:
very deep exterior recess at east (south of OB) is not good. 2:1 Width to Depth ratio recommended.
West Stair - I am not sure if you can place the door off corner
LM - SO distance: move SO door west and move AO-SO door south, move LM door east
move SM door to north wall
Windows: use segments of 4'-8' windows instead of a single large one
