There is (at least one) example of this in Cambridge, UK. King's College built a new building in the 50's that has some windows that overhang the wall into neighboring Queens' College. When Queens' built a new (one of the very earliest) brutalist building a few years later, it juts out over the same wall back into King's, blocking the views from the Master's lodge.
