How they reason — coded from their reports

Cheung has the highest refusal rate among the top officers reviewed and is exacting about EXACT compliance with a previously approved consent — refusing an S.73 variation where as-built dormer windows depart materially (shorter sashes, wrong cladding) from the consented drawings, comparing directly against the neighbouring building's treatment. On certificate-of-lawfulness applications he requires positive documentary evidence of a claimed use, refusing where the applicant supplies only undated drawings with no supporting statement, and instead relies on his own site-visit observations (paint markings, layout) to infer the most likely historic use.

Observable habits

· compares as-built works directly against the ORIGINALLY consented drawings, refusing an S.73 variation where the divergence (shorter window sashes, wrong cladding) is materially worse than what was approved

· requires positive documentary evidence (a cover letter, planning statement, dated records) for a claimed historic use on CLEUD applications, refusing where only undated drawings are submitted

· relies on personal site-visit observations (paint markings, physical layout) to independently infer a site's most likely historic use where the applicant's evidence is insufficient

What their reports consistently look for

· what this officer's reports consistently look for: whether as-built or varied works match the originally consented drawings exactly, not just approximately

· what this officer's reports consistently look for: positive documentary evidence (dated records, a planning statement) supporting a claimed historic use on CLEUD applications

· what this officer's reports consistently look for: physical evidence from a personal site visit (paint markings, layout) to independently corroborate or contradict an applicant's claimed use

In their own words

The three sash windows are much shorter than the consented scheme, resulting in an awkwardly proportioned window with a large section of sheer slate below

21/01430/FULL

the applicant claims that the basement has primarily been used for storage over the past 10 years, but no evidence has been presented to support this claim. No cover letter, planning statement, or any supporting documents were submitted alongside the application
