Understand the place
We review the available history, heritage listing information, existing fabric, setting and relevant significance to establish what is important and why.
Heritage Impact Statements · Brisbane & Queensland
Clear, evidence-based assessment for proposed changes to heritage places. We help clients understand significance, explain the design response and navigate heritage approval requirements with confidence.


Heritage impact assessment
A Heritage Impact Statement brings together the significance of a place, the proposed works and a clear assessment of their likely heritage impact.
We prepare Heritage Impact Statements for development affecting heritage-listed places, heritage settings and places subject to heritage controls. Our reports are written to be useful to clients, design teams and decision-makers: clear about the place, specific about the proposal and focused on the actual impact of the work.
Our approach
We review the available history, heritage listing information, existing fabric, setting and relevant significance to establish what is important and why.
We examine the design in detail, including demolition, new work, alterations, materials, interfaces and changes to setting, use or significant fabric.
We assess the proposal against the identified heritage values and relevant approval framework, distinguishing between impacts that are material and those that are minor, reversible or appropriately managed.
We explain how the final proposal responds to significance, why particular design decisions have been made and how adverse impacts have been avoided or minimised.
Early heritage advice
A Heritage Impact Statement is strongest when the heritage response has been considered as part of the design process rather than added at the end.
We can review options early, identify significant fabric and likely approval issues, and work with architects, planners and owners to refine proposals before lodgement. This helps create a clearer approval pathway and a more defensible final design.

When a Heritage Impact Statement may be needed
A Heritage Impact Statement may form part of an approval or design process where works affect a heritage-listed place, a heritage precinct or overlay, the setting of a heritage place, or significant existing fabric.
Typical proposals include alterations and additions, adaptive reuse, partial demolition, new buildings within a heritage setting, accessibility upgrades, services and building upgrades, conservation works and changes associated with a new use.
The required level of assessment depends on the place, the extent of the proposed work and the relevant approval pathway. We can review the available information at the outset and help establish the appropriate scope.
Common questions
A Heritage Impact Statement explains the heritage significance of a place, describes the proposed work and assesses how the proposal may affect identified heritage values. It also explains the design response and how adverse impacts have been avoided or minimised.
A Heritage Impact Statement may be requested where proposed development or works affect a heritage-listed place, a place within a heritage overlay or precinct, or the setting of a heritage place. The exact requirement depends on the relevant planning and approval framework.
Yes. Early heritage advice can identify significant fabric, likely approval issues and opportunities while the design is still flexible, reducing the risk of avoidable redesign later.
