How they reason — coded from their reports

Storey-Vowles' reports are distinctive for citing named appeal decisions on the same site directly, including the Inspector's own reasoning quoted rather than paraphrased, and for GPDO roof-volume calculations expressed to two decimal places. Refusals name each adjoining property individually by number and describe its specific impact rather than a general amenity finding.

Observable habits

· quotes a named Inspector's own appeal reasoning on the same site verbatim before applying it to the current case

· sets out roof extension cubic-metre volumes to two decimal places with the multiplication shown in full

· addresses each adjoining property individually by house number when assessing amenity impact rather than a single blended neighbour finding

What their reports consistently look for

· what this officer's reports consistently look for: a prior Inspector's appeal reasoning on the same site quoted directly, not just referenced by decision reference

· what this officer's reports consistently look for: each adjoining property assessed individually by house number rather than folded into one general neighbour finding

· what this officer's reports consistently look for: the precise multiplication behind a GPDO roof-volume calculation to two decimal places

In their own words

In justifying this decision, the Inspector stated that "The extension would be 3m deep although The Roe Green Village Conservation Area Design Guide says that single storey extensions to terraced properties should be no more than 2.5m deep. Nevertheless, although the proposed extension would be slightly deeper than this, it would have a flat parapet roof which would avoid the bulk of having a traditional pitched roof."

20/0003

The proposed two-storey side to rear extension, by reason of its design, bulk and close proximity to the boundary, coupled with the addition of a crown roof would create a disproportionately large addition and result in an incongruous and discordant feature that is out of keeping with the character of the dwellinghouse.

20/0025

Measured from 650 published Brent officer reports written by this officer, with recited policy boilerplate stripped before any counting. These describe how this officer works and writes — they are not outcome predictions. Every quote is from a named public report.
