When pedestrian on the street feels overwhelmed by the sheer bulk and size of a structure one thing is certain : It's not the pedestrian who is "out of scale" It's the building. Many large retail stores being build today have just a single entrance on a two story wall, 150 feet long. And established small town retail block may, in contrast, have (in the same 150 feet) 4 or 5 stores at a scale that is consistent with the pedestians who pass by. Achieving a "human scale" usually means avoiding long unbroken horizontal expanses, and paying attention to how upper stories of buildings retail to people on the street.
