How they reason — coded from their reports

Tassell's caseload is dominated by householder extensions, many within the Metropolitan Green Belt or the Christ Church conservation area, and he is distinctive for running the NPPF Green Belt 'proportionality' test (paragraph 152/154) as a routine first step even on modest rear extensions, checking whether the addition is 'subservient in scale' and 'tucked behind the existing dwellinghouse' before reaching the openness/inappropriate-development question. On neighbouring-amenity impact he consistently frames marginal harm against the STEPPED nature of adjoining plots and existing extensions on neighbouring properties, quantifying differences in projection to within 0.1m (e.g. 'will only surpass the extension of equal dimension on 26 Honeyden by 1.5m') rather than applying the Design and Development Control Guidelines depth threshold as an automatic cut-off. He treats equalities/human rights assessments as a genuine balancing exercise rather than boilerplate, explicitly weighing a vulnerable occupier's need for step-free access or mobility-scooter storage against modest amenity harm to a specific named neighbour before recommending approval.

Observable habits

· runs the Green Belt 'proportionality'/openness test (NPPF paragraphs 152/154) as a first-step check even on ordinary householder extensions sited within or adjacent to the Green Belt, before any design or amenity assessment

· quantifies neighbouring-extension comparisons to the nearest 0.1-0.5m (e.g. how much a new extension would 'surpass' or fall short of an existing neighbouring extension of comparable form) rather than applying the DDCG depth guidance as a flat pass/fail line

· on equalities/human-rights cases (step-free access, mobility scooter storage), explicitly states the harm being weighed against the need and reaches a reasoned 'on balance' conclusion rather than reciting the PSED boilerplate alone

What their reports consistently look for

· whether the extension is 'subservient in scale' and sited behind the existing dwelling, as the Green Belt openness test's practical proxy

· the precise depth/height differential (in metres) between a proposed extension and an existing comparable extension on the stepped or staggered neighbouring plot

· whether a Design and Development Control Guideline depth exceedance is offset by an equivalent existing extension on the specific neighbour most affected

In their own words

the extension relates sympathetically to the existing dimensions of the kitchen protrusion and complementary conservatory. The rear extension will be subservient in scale and be tucked behind the existing dwellinghouse, therefore it would not constitute inappropriate development within the green belt

23/03240/FUL

the extension proposed on 28 Honeyden will only surpass the extension of equal dimension on 26 Honeyden by 1.5
