Answer first: A view loss assessment shows council how your design affects the views neighbours and the public already enjoy. NSW councils and the Land and Environment Court test view impacts with the four-step Tenacity planning principle: what view is lost, from where, how much, and whether the design is reasonable. A compliant envelope plus a skilful design is your strongest position.

On a harbour, beach or ridgeline site, views are often the issue that decides a DA. Neighbours who look over your roof will object, council will ask how much of their outlook disappears, and if the matter goes to appeal the Court will want accurate photomontages. This guide explains how view loss is assessed on NSW development applications, what a view impact or view sharing report contains, when councils ask for height poles and photomontages, and how we design to keep a view dispute from stalling the approval.
Why does view loss matter on a NSW DA?
Under section 4.15(1) of the Environmental Planning and Assessment Act 1979 (EP&A Act), council must consider the likely impacts of a development on the natural and built environments, any submissions made, and the public interest. Loss of an existing view from a neighbouring home is one of those built-environment impacts, and it is one of the most common reasons neighbours lodge objections.
Most local environmental plans (LEPs) and development control plans (DCPs) in coastal and harbour councils include view sharing objectives or controls, but they tend to be written in general terms such as "development should allow for the reasonable sharing of views". That leaves the question of what is "reasonable" to a structured method, and in NSW that method comes from the Land and Environment Court.
What is the Tenacity view sharing principle?
In Tenacity Consulting v Warringah Council [2004] NSWLEC 140, the Court published a planning principle for assessing view sharing, set out at paragraphs 25 to 29 of the judgment. The Court describes view sharing as arising when a property enjoys existing views and a proposed development would share that view by taking some of it away for its own enjoyment. Taking it all away cannot be called view sharing, although the judgment notes it may, in some circumstances, be quite reasonable.
The Court's own planning principles page lists Tenacity as the general principle for views. Councils use it directly: Woollahra Municipal Council, for example, states that it will always assess view sharing using the Tenacity principle and the questions in paragraphs 26 to 29. The Court is also clear that planning principles are not legally binding and do not prevail over councils' plans and policies. They guide how an assessment is reasoned, but the LEP and DCP controls still come first.
The four Tenacity steps in practice
The steps are applied in order, and each one frames the next. This table summarises each step as the Court described it and what we look for when preparing a DA.
| Step | What the Court asks | What it means for your design |
|---|---|---|
| 1. Views affected | What kind of view is affected? Water views are valued more highly than land views. Iconic views (for example the Opera House, Harbour Bridge or North Head) are valued more highly than views without icons. Whole views are valued more than partial views, such as a water view where the land–water interface is visible. | Identify the exact elements of each neighbour's view that your building would touch: water, the land–water edge, a headland, a skyline or an icon. |
| 2. Where the view is enjoyed | From what part of the property is the view obtained? Views across side boundaries are harder to protect than views from front and rear boundaries. Sitting views are harder to protect than standing views. | Map which rooms and outdoor areas next door have the view, and whether it is across a side boundary or over the front or rear. |
| 3. Extent of impact | Assess the impact on the whole property, not just one view. Views from living areas matter more than from bedrooms or service areas, though kitchen views are highly valued. Rate the impact qualitatively as negligible, minor, moderate, severe or devastating. | Avoid percentages on their own. A small percentage can still remove the most valuable part of a view. |
| 4. Reasonableness | A proposal that complies with all planning controls is more reasonable than one that breaches them. Where view loss results from non-compliance, even a moderate impact may be unreasonable. With a complying proposal, ask whether a more skilful design could give the same development potential and amenity while reducing the impact on neighbours' views. | Compliance with height, setbacks and floor space ratio is your strongest argument, and you should still be able to show the design alternatives you tested. |
The fourth step is where most disputes are won or lost. As Senior Commissioner Roseth wrote in a 2005 paper published by the Court, many people obtain panoramic views because an adjoining site is developed far below its potential, and when that site is finally developed the effect on views can be hard to accept. The principle accepts that a complying building can still remove a significant view, provided a better design could not reasonably avoid it.
Public views are assessed differently
Tenacity deals with views from private property. Views from streets, parks, foreshores and other public places are covered by a separate planning principle on impact on public domain views, from Rose Bay Marina Pty Limited v Woollahra Municipal Council [2013] NSWLEC 1046 at paragraphs 39 to 49, also listed on the Court's planning principles page. If your site sits on a scenic ridgeline, foreshore or view corridor identified in the DCP, expect council to look at both private and public view impacts, often alongside a heritage impact statement where a heritage item or conservation area is nearby.
When does council ask for a view loss assessment?
There is no single statewide trigger. Each council's DCP and DA lodgement guide sets its own requirements, and assessment officers can ask for more through a request for additional information. In our experience, a view analysis is likely to be needed when:
- the site is on a slope with water, harbour, ocean or district views across it;
- you are adding a storey, raising a roof or extending towards a neighbour who looks over your property;
- the proposal breaches a height, setback or envelope control, especially where you need a clause 4.6 variation;
- neighbours raised views at a pre-DA meeting or are likely to object during notification; or
- you are modifying an approved design and the change alters the building's height or bulk under a section 4.55 modification.
Some councils spell out visual material in their lodgement checklists. Mosman Council's DA checklist, for example, asks for a photomontage for new buildings or other development with an estimated value over $1.5 million or when directed by council, and asks applicants to show impacts on a photomontage where views are an issue. Woollahra requires a 3D digital model for new buildings or changes to building form in the E1 Local Centre and MU1 Mixed Use zones, and for buildings 12 metres or higher, and uses it to assess view impacts from both private and public domains. Always check the current checklist for your council before lodging.
View issues also appear at the State level. Secretary's Environmental Assessment Requirements for State significant development have asked for a detailed view loss and view sharing assessment having regard to the Court's planning principles for views.
What goes into a view loss or view sharing report?
A view loss assessment can be a section of the Statement of Environmental Effects for a modest alteration, or a standalone report by a planner or visual impact consultant for a larger or contested proposal. Either way, a report council can rely on usually covers:
| Component | What it shows |
|---|---|
| Site and context analysis | Topography, neighbouring dwellings, view directions and the DCP view controls that apply. |
| Viewpoint inventory | Each affected property, the rooms or terraces with views, whether the view is standing or sitting, and whether it crosses a side, front or rear boundary. |
| Existing photographs | Unaltered photographs from each viewpoint, with camera location, height and lens recorded. |
| Photomontages or view diagrams | The proposed building envelope overlaid on each existing photo, as a wireframe, block massing or rendered image. |
| Tenacity assessment | A step-by-step assessment for each affected property, ending with a qualitative rating from negligible to devastating. |
| Compliance and alternatives | How the envelope compares with height, setback and FSR controls, and which design changes were tested to reduce impact. |
Accurate base data is essential. A detail and level survey with AHD levels for your site, and ideally for key neighbouring ridges, windows and terraces, is what makes the overlays credible. Our guide to survey plans for NSW DAs explains what to ask your surveyor for.
Height poles: when council wants to see the envelope on site
Height poles are temporary poles, often joined by tape, that mark the corners and high points of a proposed building so neighbours and assessment officers can see the envelope from affected rooms. Several councils, particularly on the Northern Beaches and around the harbour, ask for them where views are in dispute, usually with a registered surveyor certifying the pole positions and heights. In a 2022 Northern Beaches Local Planning Panel matter, for example, the assessment relied on a surveyor-certified height pole to assess the view impact on a neighbouring home.
Requirements differ between councils, including whether poles must be up before lodgement, how long they stay up and what certification is needed. Ask at your pre-DA meeting whether poles will be required and when.
Photomontage accuracy: the Court's 2024 policy
If a DA goes to appeal, photomontages are scrutinised closely. The Land and Environment Court's Policy: Use of Photomontages and Visualisation Tools commenced on 17 May 2024, replacing the 2013 version. It applies to appeals under the EP&A Act where photomontages form part of expert evidence. It requires:
- the existing, unaltered image;
- a 2D plan or elevation showing the camera location, target point or viewing angle, and lighting source;
- the proposed built envelope overlaid on the existing image as a wireframe or block massing model;
- where a photorealistic computer-generated image is used, matching camera metadata, environmental conditions and colour, plus the software used; and
- a methodology summary covering the survey data and surveyor, topographical data, camera type, lens and focal length, the camera's location and RL, and the rationale for each view.
The policy is written for the Court, but we prepare DA-stage montages to the same standard. A montage that would survive an appeal is far harder for an objector to dismiss at the assessment stage, and it does not need to be redone if the matter escalates.
Step-by-step: how we handle view-sensitive DAs
- Read the controls. Check the LEP height and FSR standards and the DCP view, setback and envelope controls for your site.
- Survey early. Commission a detail and level survey with AHD levels, including relevant neighbouring features where you can access them.
- Map the neighbours' views. Identify likely affected properties and which rooms and terraces face across your site.
- Test the envelope in 3D. Model the maximum compliant envelope and the proposed design, then check view lines from each affected viewpoint.
- Design for view sharing. Test lower roof forms, stepped or recessed upper levels, view corridors along side boundaries, and relocating bulk away from the most valuable view elements.
- Raise it at pre-DA. Show council the analysis and ask about height poles, photomontage expectations and likely viewpoints.
- Prepare the assessment. Produce photomontages and a Tenacity assessment for each affected property, in the SEE or as a standalone report.
- Respond to submissions. If neighbours object, address each viewpoint specifically, with additional montages if needed, rather than with a general statement.
- Keep the record. Retain survey, camera and model data so montages can be updated for amended plans, a section 4.55 modification or an appeal.
Design moves that reduce view loss
| Design move | Why it helps under Tenacity |
|---|---|
| Keeping within height, setback and FSR controls | Step 4 treats a complying proposal as more reasonable, and a non-compliant one causing even moderate loss may be unreasonable. |
| Lower or flatter roof forms and reduced floor-to-ceiling heights at the top level | Can preserve the land–water interface or a horizon line, which Step 1 values highly. |
| Recessing or stepping the upper floor | Opens view corridors from neighbours' living areas, which Step 3 weights more than bedrooms. |
| Locating bulk away from side boundary view lines | Responds to the main view corridor, even though Step 2 treats side views as harder to protect. |
| Lightweight balustrades and open structures | Reduces solid bulk in the view without losing outdoor amenity. |
| Documenting alternatives tested | Answers the Step 4 question of whether a more skilful design could achieve the same result with less impact. |
View sharing rarely works in isolation from other amenity issues. Changes that save a view can affect solar access, so we usually run the view analysis alongside shadow diagrams and privacy checks. On waterfront sites, foreshore building lines and scenic protection controls also shape the envelope; see our waterfront home design guide.
Common mistakes that trigger RFIs or refusal
- Photomontages with no camera location, lens or survey basis, which council or objectors can easily challenge.
- Assessing only the best-case viewpoint instead of the living areas most affected.
- Relying on a percentage of view lost without describing what is lost.
- Arguing that a non-compliant element has acceptable view impacts without testing a compliant alternative.
- Leaving the view analysis until after neighbours object, when the design is harder to change.
Before lodging, run through our DA checklist so view material sits alongside the rest of the package.
Frequently asked questions
Is there a legal right to a view in NSW?
No. There is no general legal right to keep a private view. What exists is a planning assessment: council must consider the likely impacts of a development, and it usually tests view loss using the Court's Tenacity principle and its own DCP controls.
What is the Tenacity planning principle?
It is the Land and Environment Court's four-step test for view sharing from Tenacity Consulting v Warringah Council [2004] NSWLEC 140: assess the views affected, where they are enjoyed from, the extent of the impact, and the reasonableness of the proposal causing it.
Does a fully compliant design guarantee approval if views are lost?
No guarantee, but compliance helps a great deal. Under step 4, a complying proposal is considered more reasonable, and if a more skilful design could not achieve the same development potential with less impact, the view impact would probably be considered acceptable.
Who prepares a view loss assessment?
For smaller projects, the architect or town planner often includes it in the Statement of Environmental Effects. For contested or larger proposals, a planner or visual impact consultant prepares a standalone report, using survey data and photomontages prepared to a verifiable method.
Do I need height poles for my DA?
It depends on your council and site. Some councils ask for surveyor-certified height poles where views are in dispute. Check the council's DA guide and ask at the pre-DA meeting so poles can be installed at the right time.
Are side views protected?
Side views are harder to protect. Tenacity notes that protecting views across side boundaries is more difficult than protecting views from front and rear boundaries, and that sitting views are harder to protect than standing views.
