How they reason — coded from their reports

Perillo's file is dominated by prior notification (PS192/PDE) reports that reduce to compliance checklists against permitted-development classes, with little discursive reasoning; his full householder (HOT/FUL) reports discuss neighbour amenity property-by-property, naming specific neighbouring addresses and giving a distance or figure (eaves height, projection depth) before concluding on overbearing, overlooking or daylight/sunlight loss.

Observable habits

· runs through PD compliance criteria as a checklist ('Compliant. Compliant. Compliant.') in PS192/PDE reports rather than narrative reasoning

· in full applications, addresses each neighbouring property by number/address in turn under 'Neighbour Amenity', giving a specific eaves height or projection figure for each

· references a previously refused or withdrawn scheme on the same site (e.g. a withdrawn application or an appeal decision) to explain why the current revised proposal is now considered acceptable

What their reports consistently look for

· what this officer's reports consistently look for: whether the proposal complies with the specific numeric thresholds of the relevant GPDO permitted development class

· what this officer's reports consistently look for: an eaves height figure (commonly 2.2 metres) at the shared boundary to mitigate overbearing/loss of light

· what this officer's reports consistently look for: whether a revised/resubmitted scheme addresses the specific reasons an earlier version was refused or withdrawn

In their own words

Inspector goes on stating that "while there is a varied rear building line at the property, the increased depth of the projection, and more substantial construction with solid sections of wall and an uncharacteristic flat roof, would result in the proposed extension being a bulky and prominent feature."

20/2365/HOT

In order to address overlooking issues, a planning condition is considered necessary and reasonable, which would require that the proposed upper floor side window would at no time be openable or glazed, otherwise than in obscured glass, below a minimum height of 1.7 metres (5'7") above the relevant floor level.

20/2099/HOT

Measured from 898 published Richmond Upon Thames 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.
