Model advice
For advice about your model, you can speak to a modeller at our Town Hall House customer service centre.
Any development that involves changes to the building envelope of the city centre requires physical and 3D (electronic) modelling to be included with the development application.
For advice about your model, you can speak to a modeller at our Town Hall House customer service centre.
The requirements for 3D CAD models can be downloaded here.
The model scale is to be 1:500 and detailed to show all:
All buildings within your site boundaries need to be modelled in detail, including existing buildings that will be retained or adapted in the development.
The model construction is to be of a professional standard using only approved materials including:
Unacceptable model construction materials include:
The model needs to be spray-painted flat white.
The model needs to show its relationship to the surrounding areas and buildings on an incremental scale showing a distance of:
Surrounding roads need to be labelled in title block with the address, north point and context shown in a contrasting colour (light grey). Clear acrylic lids are not to be fixed and must be removable without tools.
If the site context has already been modelled by us, it does not need to be supplied by the applicant. Templates of applicants' sites that have already been modelled by us are available from our modelling team.
The individual model of the proposed development needs to be able to be removed from its base and the site context. The footprint of the individual model should extend from reduced level (RL) 0.0 (Australian Height Datum) and be of solid construction (not on stilts).
Models should not be larger than 800mm × 800 mm or weigh more than 25kg.
After application approval, if there have been any external changes or if an authority other than the City of Sydney provided development approval, an updated model is required before a construction certificate can be issued.
The model must be an honest representation of the finished building. Providing extra models to a larger scale is at the discretion of the applicant.
