How they reason — coded from their reports

Karsou's caseload is dominated by side, rear and wrap-around householder extensions, and she is distinctive for a near-formulaic recurring device — citing that 'aerial photographs indicate that a few properties along [the named street]' have been altered by similar size and design extensions — as her standard evidence for established local character, deployed consistently across many different streets rather than varying her justification style. On amenity impact she runs a repeated near-identical closing formula assessing 'daylight/sunlight or increased sense of enclosure' relative to specifically named adjoining properties, and is one of the few coded officers to explicitly distinguish rear-extension depth rules for semi-detached versus detached properties (45-degree rule application varying by house type).

Observable habits

· cites 'aerial photographs' showing that a few properties along the SAME named street have been altered by similar size and design extensions, as the standard, near-formulaic evidence for established local character across many different applications

· runs a repeated closing formula assessing loss of 'daylight/sunlight or increased sense of enclosure' relative to specifically named adjoining properties by house number, applied almost identically across reports

· explicitly distinguishes how the depth/45-degree extension rules apply differently for semi-detached versus detached properties depending on separation from neighbouring boundaries

What their reports consistently look for

· aerial-photograph evidence of similar size and design extensions already present along the same named street

· the specifically named adjoining property (by house number) most likely to experience loss of daylight/sunlight or increased sense of enclosure

· whether the host dwelling's status as semi-detached or detached, and its separation from neighbouring boundaries, changes which depth/45-degree rule applies

In their own words

Aerial photographs indicate that a number of properties along Wolsey Crescent have been altered by similar size and design extensions

21/02299/HSE

In semi-detached dwellings, where there is sufficient separation from neighbouring boundaries the 45degree rule can be applied to achieve a deeper footprint than 3.5m
