A report to Tuesday night’s council meeting said current controls were not adequate to ensure that the curtilage of the state-listed heritage building was protected from incompatible development. 

The report said controls were necessary to prevent any further subdivision of the lots between Cockatoo Ridge and Aberglasslyn House and to ensure that any ancillary buildings were subject to a development application.

Councillors will vote at the meeting on whether to forward a new planning proposal to the Minister for Planning requesting a gateway determination.

The report said Aberglasslyn House was an important part of Maitland’s history and a change to the city’s local environmental plan several years ago introduced vulnerabilities to the protection of the property.

The two-storey house, with vaulted cellars, stands proud on a sweeping bend above the Hunter River.
