            <div>I would still use a more specific building value (there
              are many types of commercial buildings, see query below).
              Also consider adding building:levels because it gives a
              good impression of size.<br>

    Some of these will only have one level .. but considerable height.
    So use of the height key may be more appropriate. <br>
