The Colonia House

This is a completely different architecture than shown in this blip. The only thing in common is that they are both build on the waterside of the river Rhein, and that the view from both buildings must be great. Unfortunately, till now I was in neither of the two.

It was build in 1973 and is 147 meters high. It also is the tallest (and most probably the ugliest) apartment building in Germany.
