Where any of the above permitted uses requires the construction, extension or exterior alteration of a building, no building permit shall be issued unless the Board of Zoning Appeals has approved the building plans. Such approval shall be granted if the Board finds that the external materials of the proposed building, extension or alteration, and their color and texture, are in reasonable harmony with the external materials of any existing structure within 500 feet. The aforesaid distance shall be measured in a straight line between the nearest points on the proposed and existing structures.
