How they reason — coded from their reports

Kwok's reports cluster around HMO conversions and Green Belt extensions, and his HMO assessments consistently break out cycle/refuse storage provision as its own discrete sub-topic with a specific storage figure, distinct from the amenity assessment. On Green Belt schemes he tabulates footprint/floor area/volume percentage increases from both the original and existing building before reaching a proportionality conclusion.

Observable habits

· on HMO schemes, assesses cycle parking and refuse storage provision as its own discrete named sub-topic with an exact space count, separate from the general amenity paragraph

· on Green Belt extensions, tabulates footprint/GEA/GIA/volume percentage increase from BOTH the original AND the existing building before assessing proportionality

· cites the specific HMO policy criterion (DM30 a/b/c, HO10 sub-numbers) by letter/number when assessing large HMO conversions

What their reports consistently look for

· what this officer's reports consistently look for: the exact cycle parking space count and refuse storage arrangement for HMO/flat conversions, assessed separately from general amenity

· what this officer's reports consistently look for: the percentage increase in footprint, GEA, GIA and volume from BOTH the original and the existing building on Green Belt sites

· what this officer's reports consistently look for: whether Secured by Design measures (gates, fencing, natural surveillance) have been addressed for larger schemes
