On the site visit today, we understand that the Inspector was given a clear picture of how extensive the development would be, and how much it would impact on neighbours other than the two agreed by the council.  Matt Shillito (PegasusLife) attended, and was observed to be looking glum.

Inspector Michael Boniface must decide if, according to the rules, the proposals constitute overdevelopment.  Then he also has to assess whether the so-called public benefits outweigh any harm.
The target date for the issue of the decision is expected to be confirmed shortly (within 4 working days of the close of the Inquiry), and the decision will be published on the Planning Portal  https://acp.planninginspectorate.gov.uk. but probably not until the New Year, as the Sidmouth Herald suggests here:
