Veritas, I have been there (in E-On's headquarter) two years ago, and as far as I can remember, there is a square with a garden and trees in front of the building, just the other side of the road, so I don't think that you picked the right buildings, because this appears to have other buildings on the other side of the street. Or maybe Nicholas has replaced trees with buildings in the ecosystem of the block ;-) If I could look at a larger enlargement, I would be probably able to tell a definite word.
