Those of you familiar with Palms will know this building at the corner of Motor and National Place.

It surprises us at first to learn that this is one of the oldest business buildings in Palms; according to County records it goes back to 1915. The plastic signage belies its history by giving the place a decidedly bland post-WWII air.
From the side the appearance is more typical of when the building was constructed.

And here's the strange part. Notice how what appear to be loading doors, originally intended for trucks or boxcars, are flush against the sidewalk, which seems to make them pretty much useless as such. At the same time, in the second picture there's obviously a slight rise in the level of the street and sidewalk, and as it happens if you keep going along National Place the level soon descends again. The placement of the window seems wrong as well; it's too low. Notice also how the air duct near the window has a right-angle turn near the sidewalk.
Is it possible that the level of the street was raised after the building was built? Before there was a street, is it possible that there was a rail siding between here and the Air Line?
