WALL. A building or erection so well known as to need no definition. In general a man may build a wall on any part of his estate, to any height he may deem proper, and in such form as may best accommodate him; but he must take care not to erect a wall contrary to the local regulations, nor in such a manner as to be injurious to his neighbors. See Dig. 50, 16, 157. Vide Party Wall.
