The "original shape" of this building was (or started as) a T shaped building. To the right where the antenna is, was the top of the T. The left side of the picture was the base of the T.
Where the "new additions" were built, the roof pitch changed by about 2 degrees (according to several sets of plans I have). The roof overhang maintained its pitch throughout the main structure, but once passed this point in the additions, the roof pitch was "lessened".
Noted here with the two green vertical lines.
