2. Setback Exceptions. In all districts (except where subject to the provisions hereof on "Corner Clearance"), a building may be constructed as near to the line of any street as the average of the set-backs of the dwellings or other main buildings nearest thereto on either side of the building in question. Where, in determining the average setback, the nearest main building on either side is more than three hundred (300) feet from the building in question, such side building shall not be counted, but instead the intervening space shall be considered as though occupied by a main building having the required setback (whether or not said space is laid out as a separate lot).
