Your right and wrong the warehouse you can see though the doors...

Your right and wrong the warehouse you can see though the doors is free standing (in relation to the building behind it) and the building behind it is 6 stories when looking from the pictures perspective and the headquarters is most likely not what you see in the background, the warehouse most likely runs long ways from the headquarters.

Not everything is easy to indentify it depends on who held the camera just think if you took a photo of the end of the warehouse it would show the headquarters behind it but then what would you see of the warehouse?
They wanted a picture of the front of the headquarters (which hides the warehouse), but they also wanted a picture of the warehouse and they've taken it to capture the fullest extent of it which does not show the HQ which must be to the left of the warehouse picture.

Perhaps even the the warehouse is a building block away from the HQ? but they must be close as they describe the buildings as being adjacent which would mean very close but not necessarily touching.
