The 28 homes in the frame to join the heritage list in Orange, NSW

Orange City Council has accepted a recommendation that 28 properties in Orange and Huntley be considered to be added to the Local Heritage item list.

The additions follow 40 days of public exhibition of changes to heritage listings in the region.

The heritage report said properties on the list include a former railway crossing keeper's house on Dalton Street and an example of a 'Stroud' house in Spring Street.

"This range of pre-fabricated timber houses was made in Stroud (NSW) in the vicinity of the forest and timber mill and then sent to Orange by train for local erection," it said.

"The efficient floor plan located all the plumbing in one portion to reduce the plumbing cost, kitchen, bathroom and laundry."

Nearly all of Hawkins Lane in east Orange will be added to the heritage list.

However, the owner of one property in the street requested it not be included following a major rebuild including the addition of a two-storey extension in 2006.

Other submissions questioned how heritage listing would affect property values and whether the property owners would be allowed to renovate in the future.

Changes has also been made to the size and names of various heritage areas in the city, mainly in east Orange.

They include expanding the Duration Cottages area at Glenroi with houses built for workers at the WWII arms factory which later became the Electrolux site.

The area has been extended to include properties in Amber Street and a church property on the corner of Glenroi and Churchill avenues.

Another heritage area also expands into Spring Street which a staff report to council's meeting this week said had been the recent subject of possible housing changes.

"Of particular interest to council will be the expansion of the Heritage Conservation Area of Newman Park that takes in site that in the past has been the subject of a boarding house proposal, along with the area of Spring Street and Summer Place, which recently received publicity due to investigations by NSW Land and Housing Corporation into affordable housing," it said.

The largest property included on the list is the81-hectare Waverton property at Huntley which has an historic dairy and outbuildings.

It is described as a "rare example of a demonstration dairy." A submission said the demonstration farm was part of an improvement plan partly funded by the Department of Agriculture in the early 1950s.

The following properties are recommended to join the list:
