Imagine the scenario:
You’ve just signed off on your final plans.
The architect has finished the drawings.
The builder has priced the job.
You’ve signed the contracts.
All forms have been completed.
Your Development Application has been submitted through the NSW Planning Portal.
You’re thinking:
“If everything goes smoothly, we could be in before Christmas.”
Finance is approved.
Construction timelines are pencilled in.
Your rental lease end date is mapped out.
Everything feels aligned.
Then an email arrives from Council.
“The Development Application submitted requires additional information.
Please provide a Heritage Impact Statement as the site is located within a Heritage Conservation Area.”
Your stomach drops. You were sure everything was taken care of and the DA process was now just a formality.
No one mentioned a heritage report for lodgement.
Not the builder.
Not the designer.
Not when you signed the contract.
The DA process is now stalled and the phone starts ringing.
Your builder starts asking questions.
You’re still paying rent.
Your finance approval has time limits.
Material costs are rising.
A small oversight suddenly feels like a major problem.
If this sounds familiar — you are not alone.
We regularly assist homeowners and project builders who only discover the heritage overlay after Council assessment has begun.
The important thing to understand is this:
In most cases, it is entirely fixable — and often without redesigning the project or derailing your timeline.
What matters is acting quickly and providing Council with a properly structured Heritage Impact Statement that addresses the relevant planning controls and heritage objectives.
Even experienced builders and architects can overlook heritage requirements for development applications.
Common reasons include:
In NSW, heritage triggers are governed by:
Many Sydney suburbs — particularly Inner West, North Sydney, Parramatta, City of Sydney, Randwick and Canterbury-Bankstown — contain extensive Heritage Conservation Areas.
A Heritage Impact Statement is not a generic supporting letter or a simple design justification. It is a structured planning document that must be prepared by an experienced heritage consultant who understands both heritage principles and the NSW planning framework. Council is not simply looking for confirmation that the design “looks appropriate” — they require a clear, reasoned assessment that demonstrates how the proposal responds to the heritage significance of the site and its broader context.
In practical terms, Council wants to understand whether the development respects the established scale and bulk of surrounding buildings, whether the roof form and articulation are consistent with the prevailing heritage character, and whether proposed materials and finishes are sympathetic to the conservation area. They will assess whether any demolition removes contributory fabric, whether new elements dominate the streetscape, and whether the proposal aligns with the specific objectives of the relevant Heritage Conservation Area. Even where the site itself is not a listed heritage item, the cumulative impact on streetscape character is a key consideration.
A properly prepared Heritage Impact Statement directly addresses the heritage clause of the applicable Local Environmental Plan (typically Clause 5.10), the relevant heritage provisions within the Development Control Plan, and the underlying objectives of the conservation area. It also draws upon established heritage assessment methodology, including the NSW Heritage Council guidelines and, where relevant, the principles of the Burra Charter. The report must clearly identify the heritage significance of the site and surrounding context, assess the impact of the proposal against that significance, and provide a reasoned conclusion as to whether the development is acceptable.
When structured correctly and prepared by an experienced heritage consultant, the document gives Council confidence that the heritage implications have been properly considered. This allows assessment to proceed without unnecessary delay and significantly reduces the risk of further requests for information.
If you’ve received a request from Council for a Heritage Impact Statement, the most important step is acting quickly — but strategically.
The process is usually straightforward.
Once you contact us, you can simply email through your architectural plans, the site address, and the Request for Information (if one has been issued). We will review the documentation promptly and provide a clear fee proposal outlining the scope of work and anticipated timeframe.
If your situation is time-sensitive — and many are — it is helpful to let us know upfront. Where clients are facing contract deadlines, rental costs, finance expiry dates or builder scheduling pressures, we can factor urgency into our programming. In some cases this involves adjusting internal workflow or undertaking after-hours work to achieve a short turnaround. Clear communication at the outset allows us to manage logistics properly and deliver efficiently.
Our fee proposals are issued via Xero for acceptance. Once approved, we commence immediately.
To streamline preparation, it is beneficial if photographs of the site and surrounding streetscape are provided at the outset, along with any previous correspondence from Council. The more complete the information, the faster we can progress the assessment. Where necessary, we will undertake a site inspection as part of the review process.
All Heritage Impact Statements are prepared by an experienced heritage consultant with extensive experience working with Councils across NSW and internationally. Each report is structured to address the relevant Local Environmental Plan provisions, Development Control Plan controls and heritage objectives specific to the site. The goal is not simply to satisfy the RFI, but to provide Council with a clear, reasoned assessment that allows them to confidently continue determination of the application.
Once the draft report is completed, it is issued to the client for review. This ensures you are comfortable with the content before finalisation. Following any minor clarifications or adjustments, the final Council-ready document is released for submission.
Importantly, our quoted fee includes responding to reasonable follow-up comments or minor revision requests from Council relating to the heritage assessment. We understand that the objective is to see the DA approved — not to generate multiple variations in consultant fees.
We do not require upfront deposits to commence work. However, full payment is required prior to release of the final document. A draft copy is provided for review in the interim.
In most cases, when engaged promptly and provided with complete documentation, we are able to deliver urgent Heritage Impact Statements within a short timeframe. Acting quickly and providing Council with a properly structured report is often all that is required to get your DA back on track.

Discovering that a Heritage Impact Statement is required after your Development Application has been lodged can feel like a major setback. In reality, it is often a procedural issue that simply requires the right documentation prepared by an experienced heritage consultant.
The key is acting quickly and ensuring the report properly addresses the relevant planning controls and heritage objectives. When structured correctly, a Heritage Impact Statement gives Council the confidence to resume assessment without unnecessary delay.
If you have received a Request for Information requiring a heritage report — or suspect one may be coming — contact us as soon as possible. Early engagement allows us to assess urgency, confirm scope and deliver within the shortest achievable timeframe.
You can email your plans and Council correspondence directly to us for review, and we will respond promptly with clear advice and a fee proposal.
In time-sensitive situations, clarity and experience matter.

A Heritage Impact Statement (HIS) explains how proposed works may affect the heritage significance of a property or area. Learn when you need one and how to prepare an HIS that supports your development application in NSW.
We have been engaged for many development applications for change of use and other developments within the Queen Victoria Building. The site is a state heritage listed property that has a wonderful history. We have provided heritage impact statements for the fit out and change of use for stores within the building as any works within the historic building require development approval from Council.
Heritage impact statements can be expensive. We understand that this report can sometimes be the most expensive report for a development application. We go into detail of what goes into the report and how you can minimise your costs to obtain a HIS.
We have been engaged for many development applications for change of use and other developments within the Tramsheds complex at Forest Lodge. The site is a heritage listed property that has undergone substantial rejuvenation to turn a once dilapidated building into a thriving retail/food destination.
We recently worked on a project within “The Spot”, a heritage conservation area within Randwick Council. The project was for alterations and additions to an existing semi-detached dwelling. We give some information about the project and how we assisted our clients with their development application.

Planning a renovation within a heritage conservation area? We talk about the requirements and what you can and can’t do without approval. Find out what is required with any development application and the process with heritage conservation areas and how to obtain approval with our help.
The statement of environmental effects is the most important report for a development application with Council. It is the cornerstone of any good development application and provides details of the development and an assessment of the compliance of the proposal against the relevant legislation and development controls (LEP and DCP). A good statement of environmental effects can make the difference between an approval or a refusal and can streamline the timeframe of the process.
Where a development doesn’t comply with the LEP development standard (such as minimum lot size, height of building and Floor Space Ratio) a variation to the development standard can be sought through the inclusion of a clause 4.6 report. We provide details regarding the report and where a variation might be appropriate.
Crime Prevention through Environmental Design (CPTED) is a crime prevention strategy that focuses on the planning, design and structure of cities and neighbourhoods. We discuss the principles of CPTED that are required to be assessed in any Crime Risk Reports for development applications.
