Buildings of outstanding or unusual character and architectural significance. These were to be recommended to the National Trust for immediate classification, and recommended for inclusion on a Council Register.
Buildings which do not, strictly speaking, fall into category 1, 2, or 3 but which contribute positively to the built environment. These are mainly houses of the Federation period, early 20th Century buildings whose form and materials fit well with the earlier architecture. Some interesting modern buildings are included in this category.
