How they reason — coded from their reports

Olivo has a comparatively high refusal share among the coded officers (18 of 51 sampled) with a caseload spanning larger new-build dwellings and flat/HMO conversions, and she consistently presents the full London Plan required-vs-proposed GIA/bedroom-size/amenity-space table for every application before reaching a design or amenity finding, treating each dwelling type's national space standard as the explicit numeric anchor. On design she is willing to find a scheme 'top-heavy' or 'dominating' relative to the street even where individual design cues (front bays, dormers) are individually drawn from existing local features, distinguishing between echoing local features and exaggerating them to an incongruous degree.

Observable habits

· presents the full London Plan required-vs-proposed GIA/bedroom-size/private-amenity-space table for essentially every application before reaching any design or amenity finding, anchoring the assessment in the specific national space standard for that dwelling type

· distinguishes between a design that echoes existing local features (front bays, dormers) and one that exaggerates those same cues to an incongruous, 'top-heavy' or 'dominating' degree relative to the street

· on single-aspect units, requires the single-aspect view itself to be of demonstrably higher quality, and refuses where windows are only obscure-glazed and therefore provide no genuine outlook or natural light

What their reports consistently look for

· the full required-vs-proposed GIA, bedroom size and private amenity space figures against the specific London Plan national space standard for that dwelling type

· whether a design merely echoes existing local features or exaggerates them into an incongruous, dominating result relative to the street

· whether a single-aspect unit's non-obscured windows genuinely provide outlook and natural light, rather than being obscure-glazed and functionally blind

In their own words

the proposed design takes these ques and exaggerates them to appear overly dominating when viewed in conjunction with the rest of the properties on Sinclair Road

240341

The flat has severely limited single-aspect outlook given its only non-obscured windows face the road.
