Verified Views and Planning Photomontages (AVRs)

What verified views and AVRs mean in planning

Neither verified view nor accurate visual representation (AVR) is a term defined in planning law, so it helps to tie them to the guidance that planning professionals actually work from. The Landscape Institute's Technical Guidance Note 06/19, Visual Representation of Development Proposals, was published in September 2019. It remains the current note while the Institute reviews it, and it sorts visualisations into four types according to how rigorously the image is tied to the real world.

When consultants and officers ask for verified views or AVRs, they normally mean Type 4: a photomontage whose camera locations and reference points have been fixed by survey, so the scale and position of the proposal can be checked by anyone who repeats the work. Type 3 uses the same compositing technique but aligns the model to the photograph itself rather than to surveyed coordinates. London adds a separate layer. The London View Management Framework of 2012 has its own AVR classification, numbered 0 to 3, for the views it manages; those numbers belong to the framework, not to the Landscape Institute, and the two systems should never be mixed up on a sheet.

• Type 1: an annotated viewpoint photograph.
• Type 2: a 3D wireline or model view.
• Type 3: a photomontage or photowire.
• Type 4: a photomontage or photowire that is survey and scale verifiable.

What we produce: camera-matched photomontages

Our work sits at Type 3. We take your photograph of the existing view, build the proposal in 3D from the planning drawings, and recreate the camera that took your photograph inside the model. The camera is placed at the position you recorded, given the focal length you noted, and then adjusted until the modelled context lines up with what is in the frame: building corners, kerb edges, ridge lines, window heads, lamp columns and boundary walls. When those features coincide, the proposal is rendered from the same camera, lit to match the sun and sky in your photograph, and composited into it.

The honest description of that result is a photomontage that is accurate to the photograph and to the recorded alignment. It is not survey-verified, and we never present it as if it were. For a large share of applications, including most householder schemes, extensions, infill houses and small residential developments, that is exactly the proportionate level of evidence. Officers see a realistic, traceable image, and the methodology note tells them precisely how it was made.

Where an authority or a consultee asks for survey-verifiable Type 4 views, the survey is commissioned by you or your planning consultant from a surveying firm of your choosing. If you supply the camera positions and control points fixed by that survey, we build the montage to that data instead of to visual alignment, and the methodology note records the survey as the source. What we will not do is call an unsurveyed image verified.

How to photograph the site for us

The quality of a photomontage is set on the day the photographs are taken, so a few minutes of care at each viewpoint pays off later. You do not need specialist equipment; a good camera or a recent phone held level will do, provided the details below are noted. If the officers have already agreed viewpoints at pre-application stage, photograph those exactly; if not, take several candidates for each view and we will help you choose.

Fixed reference features are what make an accurate match possible. A frame that contains only hedges, trees and sky gives us nothing reliable to align to, while a frame that includes a neighbouring gable, a kerb line or a telegraph pole lets the model lock into place. Aim for the widest frame that still shows the site clearly, because the extra context usually contains those features.

• Hold the camera at normal standing eye height, roughly 1.5 to 1.7 metres, not raised overhead or crouched.
• Keep the horizon straight and the camera level, without tilting up to fit a tall building in.
• Use the widest frame that still includes fixed reference features such as corners, kerbs, walls and poles.
• Note where you stood: a pin on a map, a marked-up site plan or a photograph back towards the spot.
• Note the lens or zoom setting and avoid digital zoom; send the original files, because their metadata often records it.
• Note the date and time, or keep the camera clock correct so the metadata records it for you.
• Take several candidates for each view, a step or two apart, in steady light.

The method we document with every montage

A convincing image is only part of the job. The other part is being able to show how it was made, so that a planning officer, a consultee or an objector can follow each step without taking anything on trust. Every study we deliver includes a short methodology note written for a planning audience. If a view is questioned months later at committee or appeal, the note answers the question.

The note is deliberately plain about where each piece of information came from. Camera positions and lens details are recorded as supplied by you, not presented as our measurements, and the alignment section explains which visible features the model was matched to. A reader can therefore judge the image for what it is: accurate to that photograph and that alignment.

• Which photograph was used for each viewpoint, with the original file name.
• The camera position as supplied by the client, shown on a viewpoint plan.
• The lens or zoom setting and the resulting horizontal field of view.
• The date and time of the photograph, so the lighting match can be checked.
• How the model was aligned, naming the features in the frame it was matched to.
• The drawings and model revision used, so the image traces back to a design.
• Any retouching applied, described in plain words, and the visualisation type stated.

When a local planning authority asks for photomontages

Many householder applications and minor schemes need nothing beyond clear drawings and perhaps an illustrative street view. Photomontages become useful where the visual effect of the proposal is itself a planning question. Common triggers are a site inside a conservation area, which the local planning authority designates; a proposal that affects the setting of a listed building, where the relationship between old and new is often how the impact is judged; and, in the capital, a scheme within a view protected by the London View Management Framework.

Requirements are set locally. Each authority publishes a validation checklist, usually called the local list, and pre-application advice is the right moment to agree which viewpoints officers want and which visualisation type they expect. Ask specifically whether camera-matched Type 3 montages are acceptable or whether surveyed Type 4 views are required, because the answer decides whether you need to commission a survey. Statutory determination periods are eight weeks for most applications and 13 weeks for major development, so it pays to settle this early.

Honest limits of a photograph-based montage

A montage built from an unsurveyed photograph is as good as the photograph and the alignment, and no better. If the recorded standing position is a few metres out, or the frame contains few fixed features, the alignment carries more judgement and the result carries more tolerance. We tell you when a view is weak for that reason and suggest a better frame rather than producing an image that looks precise but is not.

Some things a photograph cannot show either. Seasonal screening changes through the year, so a summer photograph will flatter a scheme behind deciduous trees; if winter conditions matter, the winter photograph has to be taken in winter. Proposed planting is shown at the size it will be when planted unless the brief asks for a stated future year, and the assumption is printed on the sheet. Existing buildings and street furniture stay in the frame; nothing is edited out to flatter the proposal.

Photomontage versus marketing CGI

A marketing image is composed to persuade. The camera goes wherever the angle is best, the lens is chosen for drama, the sky is picked for mood and the planting is often shown mature. That is right for a brochure, and we produce plenty of exterior CGIs for exactly that purpose.

A planning photomontage is composed to inform. The camera sits at the viewpoint you photographed, at eye height, with its lens declared; the sky and light are those in your photograph; and the proposal is shown honestly within its context. Both kinds of image can come from the same model, but they follow different rules and should not be swapped. Our guide to CGIs for planning applications explains where each fits in a submission.

Outputs for each viewpoint

Each viewpoint is normally presented as a short sequence, so the reader can compare the existing view, the outline of what is proposed and the finished montage side by side. The wireline is especially useful to officers because it shows the full extent of the building even where trees or existing buildings would hide part of it.

Sheets carry the viewpoint number, the date and time of the photograph, the lens and the visualisation type, so a single sheet makes sense on its own. Files are supplied for the application documents and as 4K images for showing on a screen at committee or design review. Where neighbouring consented schemes matter, we can model them from their published planning drawings and show them in a separate cumulative version, clearly distinguished from your proposal.

• Your photograph of the existing view, as the baseline.
• A wireline showing the outline of the proposal, with hidden parts marked.
• The rendered photomontage, lit to match the photograph.
• Optional cumulative views where other consented schemes are nearby.

Committee, design review and appeals

Where an application goes to a planning committee rather than being decided under delegated powers, photomontages are often the images councillors remember. We prepare screen versions with the same captions as the submitted sheets, so nothing shown on the night differs from what was formally submitted.

If an application is refused or not decided in time, the visual material may be examined at an appeal to the Planning Inspectorate. That is where a frank methodology note earns its keep: an image that states its source photograph, its camera data and its type is far harder to undermine than one that claims more than it can prove. In England decisions are made against the local plan and the National Planning Policy Framework (NPPF), while Wales follows Planning Policy Wales; the method we document is the same in both.

If the design changes through amended plans, the aligned camera is kept, the proposal is updated and the affected views are re-rendered onto the same photographs. The methodology note is reissued with a revision line, so everyone can see which views changed.

Scoping and pricing a photomontage study

Photomontage and verified view work is quoted per project, with the method documented. The quote lists the viewpoints, the visualisation type for each, how much surrounding context has to be modelled and which outputs are included, and it arrives within one business day of receiving the drawings and your photographs or proposed viewpoints. If the planning team is still deciding on viewpoints, we can quote on a provisional number and confirm once they are agreed.

Once the photographs are in hand, modelling and rendering follow the same rhythm as the rest of our work: a draft render with materials and lighting close to final, up to 4 revision rounds and finals at 4K, typically within 5–7 business days, assuming mark-ups come back within a day of each draft. Projects in the capital often pair a photomontage study with marketing images, and our page on 3D rendering in London covers that pattern. Looking for prices on the rest of the work?
