Have you tried one of the sites that superimposes the direction to
satellites on top of Google Maps? E.g. http://www.dishpointer.com

Tried that one; it's better than the one I used before. It shows that
the line-of-sight to the satellite is about 0.1 degree more than the
angle of the rear, NE side, of the building (just guessing, it barely
converges with the rear of the building over a distance of about six
stairs spacing; maybe 500 feet).

Amazing coincidence.

So if the dish is fixed a few feet from the wall it _should_ work.

Thanks for the pointer.
