The heritage lobby is predicting wholesale destruction of the city's character suburbs following an interim call to loosen heritage rules.
The independent panel hearing submissions on the council's Unitary Plan has rejected a council proposal to protect all pre-1944 houses not already covered by special character or heritage controls.
The panel said based on evidence, the pre-1944 buildings are not deserving of historic heritage scheduling or inclusion in a special character area.
The panel does not support the inclusion of additional special character areas in the plan "at this stage" and says they should be addressed by a future plan change - a legal process that can drag on for years.
"The pre-1944 demolition control overlay is placing unnecessary constraints and burdens on landowners seeking to develop their properties," the panel said in a interim guidance decision released yesterday.
