Planning CGIs

Verified views, photo-montages & Accurate Visual Representations support planning applications & give confidence to the relevant authority that your scheme is depicted as accurately as possible.


Do you need accurate renderings that perfectly illustrate your development & help you get planning approval?

Planning imagery 

Being instructed to acquire planning imagery to support an application can be a technically complex and resource challenging process. Getting it right is easy if you choose the right provider. Getting it wrong can cause you a lot of unnecessary expense, stress and hassle.

The process of creating photo-montage planning images uses both 3D geometry and photography, but lacks specific viewpoint data to determine a precise camera match.

Photo montages 

Photo montages can be creatively directed by our clients as they wish, however, we advise when particular planning protocols should be considered as part of good practice.

They are a method of evaluating a scheme's realistic visual impact within its context. For example, planning CGIs are usually, but not always, taken from a pedestrian level and from a common area of pedestrian footfall.

Verified Views 

It is important to understand that architectural photo montages are considered as an artistic impression, and the spatial accuracy of them might be questioned.

It is for this reason that Accurate Visual Representation (AVR) production came into practice in the 1990s that utilises a combination of 3D modelling, rectified photography and accurate spatial survey to produce Verified Views.


Accurate Visual Representations, sometimes called Visually Verified Montages (VVMs), combine site specific survey data, photography and the scheme's 3D geometry to create a legal document in the form of a verifiable image.

This can be used as evidence to support planning applications, in particular for Townscape Visual Impact Assessments (TVIAs).

AVRs are solely used for assessing impact within the London View Management Framework (LVMF).

Accurate ground survey 

There are four classification types of AVR informed using accurate ground survey:

AVR Level 0 - location and size of proposal

AVR Level 1 - Location, size and degree of visibility

AVR Level 2 - As level 1 + description of architectural form

AVR Level 3 - As level 2 + use of materials

AVR 0 being the most cost effective but AVR 3 giving the most convincing representation.

Reports included 

All of the data used to create the images is collated and provided in an AVR Methodology & illustrated Camera Report with appendices.

This data can then be made available for an external consultant to carry out an independent study to confirm the accuracy, should it be required.

The AVR 3 images below compare the accuracy of the as built "before" projects to the left, compared with the submitted planning imagery we created "after" on the right.
