Maybe that is the point maybe? If you had skyscrapers in the regular village limits, then the faces would be blocked out. The free land behind the faces is ideal if you think about it. Plus then the regular entrance to the village remains unaltered as well, being able to keep the 'hidden in leaves' theme. Similar principle as Washington DC has made it mandatory that no building in the vicinity of the National Mall can be as high as the Monument. The monument must appear as the tallest and most prominent sight in its field of view.
