(ii)The plan should ordinarily be on a scale of 330 feet to an inch, or 165 feet to an inch. The former scale should be adopted unless it is found too small for practical purposes. For congested areas and in other cases where the plots are very small a large scale of 82 ½ feet to an inch or 41 ¼ feet to an inch may be used. These larger scales may be used, if necessary, in the case of buildings.
