How they reason — coded from their reports

Corrie is exacting about checking whether a design element already accepted under a directly comparable PRIOR permission on the same site remains 'in keeping' when it changes in the new application, allowing an element that departs from a predominant local pattern only where it precisely matches the EXISTING building's own form (not the wider street's). He notes explicitly where an open enforcement case exists for unauthorised commenced works, records that they have since stopped pending the outcome of the current application, and negotiates ground-floor extension elements out of a scheme entirely in response to a neighbour's overlooking objection.

Observable habits

· checks whether a design element already accepted under a directly comparable prior permission for the same site remains in keeping when the detailed design changes in a resubmission

· accepts a departure from the wider street's predominant pattern only where it precisely matches the EXISTING building's own specific form, not the street generally

· records an open enforcement case for unauthorised commenced works explicitly, noting that works have since stopped pending the outcome of the current application

What their reports consistently look for

· what this officer's reports consistently look for: whether a changed design element remains in keeping with what was already accepted under a directly comparable prior permission for the same site

· what this officer's reports consistently look for: whether a proposed departure from the wider street's pattern matches the EXISTING building's own specific form

· what this officer's reports consistently look for: whether an open enforcement case for unauthorised works has been halted pending the outcome of the current application

In their own words

Whilst this is not in keeping with the predominant Item No. pattern of roof forms on this side of the mews, given that it matches the height and form of the existing building, the proposed rear treatment would not cause any further harm

20/00790/FULL

There is currently an open enforcement case at the application site relating to the commencment of building works prior to the determination of this application (21/73800/M)
