Received and replied.
With the week that's in it, I will look at this and revert probably on Friday.
It sounds like you did everything correctly but the way may not have been properly prepared by your agent.
They may not have read the development plan and noted the Conservation Area or talked to the Planner by phone.
To be fair to him/her in applications like this the Conservation Officer can be a bit of a dark horse, they seldom attend pre-planning meetings.
This points the way to the fact that the work must be done before the meeting, in terms of citing precedent in the Council's own area and elsewhere.
In other words, you'll be coming back from a refusal, and with this kind of reply likely, the groundwork must be done.
In other words, "Fail to prepare, prepare to fail."
In the meantime you may get other advices from the regulars here.
