Council subsequently lodged a planning proposal to heritage list the 12 properties, as well downzone the existing sites from R4 High Density Residential with 12 metre height limits to R3 Medium Density Residential and an 8.5 metre height limit. The rationale behind this was that any high-density residential development on Parraween Street would result in a fundamental conflict and inappropriate interface with future listed heritage items.

Although gateway approval was issued by the Department of Planning to heritage list and downzone the sites mid-2023, Council reconsidered its stance and made a post-exhibition change. The change responds to the independent heritage review prepared by Kemp & Johnson Heritage Consultants for Council.

With the amended LEP being gazetted on 7 May 2024, the properties at 78 – 88 Parraween Street have been identified as local heritage listings within Schedule 5 of North Sydney LEP, whereas the remaining six properties have not been listed. The downzoning was also dropped by Council. The reason being that the group of homes from 78 – 88 Parraween Street form a contiguous group of relatively intact houses and are good examples of modest Federation Queen Anne style houses.
