Introducing AVR images. Assisting you in the planning process

AVR ImagesAVR is an industry abbreviation of Accurate Visual Representation. They are not estimates, but accurate visuals that help allay public and local authority concerns, often speeding up planning applications in the process.

AVR views are the accepted way of accurately showing a project in it’s intended context. It’s size and mass are depicted correctly and can be displayed in a number of ways.

These images are becoming more commonplace in the planning process. Many major schemes in our cities use these images as part of their planning application submissions. Often a scheme may be in a sensitive area of the built environment and with the use of AVRs, the local authorities can be assured of their impact or lack of impact.

They can also bring added value to client and Architect by means of backward engineering a design. Local Authorities will often refer to key viewing locations in our cities and towns when considering applications for new development. Backward engineering these views (a subject to follow in future posts) can result in creating a design envelope to maximise the use of size and volume of a scheme.

The images below show three recent AVR studies (to see larger versions, click on the images to open a new window).

Study 1

In this example the vacant site in the foreground was fit for development. The base photograph was taken.

Fixed points are surveyed and the photograph is imported into 3D software ready for camera matching.

The model is located and orientated correctly to the camera. The camera matching is then carried out using various techniques.

Once the camera matching has been done and checked again, the final image can be computed and output in a number of ways. In this instance the final image needed to be a correctly lit model and have the specified materials shown.

Study 2

Here AVR images were produced to show the possible impact of several wind turbines. Existing view top with the proposed underneath.

Study 3

The final study below shows an existing situation at roof level on a block of town centre flats.

The AVR images in this scenario are used to show the impact at roof level from a certain viewing location.

Again, fixed points are surveyed and this information, together with the base photograph is imported into 3D software where the camera matching can take place.

The model is created and located correctly. Camera matching is re-checked.

The final image was an evolution through three versions. The first was, what is commonly refered to as, a wireline view. This type of image is used to show the outer extent of the proposal without the need for detail of the structure itself.

Second, ghosted colour was added within the extent of the structure.

Lighting and materials were added to create the final version of the view.

There we have it. Three examples of where AVR images can help explain proposed schemes and determine the impact, if any, on their surroundings.
