How they reason — coded from their reports

Grierson's caseload includes a higher share of heritage-sensitive and Metropolitan Open Land/Green Belt cases than the other volume officers, and his reports weigh a scheme's individual design elements separately before reaching an 'on balance' overall verdict — a two storey side extension judged acceptable 'when considered on its own' can still be refused once considered 'in tandem with' an excessively deep rear extension, treating cumulative massing as the determinative test rather than each element in isolation. He is comparatively willing to refuse on tree-related grounds where the Council's own Principal Tree Officer disputes an applicant's arboricultural report ('does not agree with the findings and recommendations of the submitted arboricultural report, which fails to meet BS5837 standards'), rather than deferring to the applicant's own technical evidence.

Observable habits

· assesses each element of a composite scheme (e.g. side extension, rear extension) separately for acceptability 'on its own', then re-tests the combination 'in tandem' before the final verdict, rather than reaching one verdict on the whole scheme at once

· on Green Belt/Metropolitan Open Land sites, applies the specific volume-increase percentage test (e.g. the 30% external volume threshold) rather than a general openness/character judgement

· gives explicit weight to a disagreement between the Council's own Principal Tree Officer and the applicant's submitted arboricultural report, favouring the in-house assessment where BS5837 standards are not met

What their reports consistently look for

· whether a composite scheme's design elements remain acceptable when assessed together ('in tandem'), not just individually

· the specific Green Belt/MOL volume-increase percentage a proposal represents against the original building or structure

· whether the applicant's arboricultural report meets BS5837 standards where the Council's own Tree Officer has raised a substantive disagreement

In their own words

when considered in tandem with the excessively deep and unsympathetic single storey rear extension, the proposed extensions would result in the addition of a large incongruous form

DM2022/00284

does not agree with the findings and recommendations of the submitted arboricultural report, which fails to meet BS5837 standards or provide an accurate representation of the development impacts upon the adjacent street trees
