This was difficult proposal as it involved doubling the size of two commercial buildings and this also meant removing an existing hedgerow boundary at the site as these extensions had to extend into an adjacent field.  The extensions are highlights in yellow in the drawing extract and the black line running through them indicates the old site boundary.  The photograph below shows a view from that field looking back at one of the existing buildings.

As stated this was sensitive landscape in the AONB and adjacent to the Avebury World Heritage Site and as such RCC secured the services of a landscape architect to provide a full assessment of the potential visual and landscape impact of the proposal.  In addition RCC had to bring on board an archaeologist, ecology consultant and a drainage consultant to provide all the necessary supporting information required for this scale  and type of application.

Whilst we attained the support to the principle of the proposal from the planning officer some objections were received from some of the council's consutlees (landscape and drainage).  RCC coordinated the additional details/rebuttal submission on these issues and the result was that all objections were removed and planning permission was granted.

This was far from a quick or straightforward process and it shows that you do need a robustly presented application to give you the best chance of success.
