 The village has grown by acquisition of land surrounding its original planned area, and portions of Nolen's design were either not fully implemented, or have undergone subsequent alteration that is not in keeping with the plan.These are generally small and the alterations are rarely intrusive.When the village was surveyed for National Historic Landmark designation in the early 2000s, the only areas of the village that were omitted from the landmarked area were the hospital and high school areas in the east, and small areas north of the historic bounds.the high school's design reflected some rather radical architectural and educational ideas not in keeping with the traditional architecture of the village.
