What you can and can’t do to a heritage-listed home will vary between state/territory and local councils. Rules generally revolve around preserving the style and appearance of the property, especially at the front façade of the home and any original features, and keeping a balance between the old and the new.
Development consent is required from your local council and state or territory’s heritage council when altering or renovating a heritage-listed home. There are generally limitations on extending upwards, however the rear of the property can often be modified to include a low-rise extension.
As architects with heritage experience we can advise prior to purchasing a heritage home. We have worked closely with local councils and understand what modifications will be possible. This can save making any costly mistakes before any decisions are made.
