How they reason — coded from their reports

Kotoh-Mortty writes narrative, numbered-paragraph reports (the 'LONDON BOROUGH OF ENFIELD' committee/delegated template) and leans heavily on a vocabulary of townscape 'typologies': he repeatedly frames a scheme's acceptability in terms of whether it 'maintains a subservient appearance' relative to the host dwelling and whether it disrupts the 'common alignment of rear extensions' along a street. He is comfortable naming a specific harmful pattern by name, coining a 'leapfrogging effect' where a cumulative rear-extension depth would distort the established building line.

Observable habits

· assesses extensions against 'character typologies' of the specific street rather than the DMD11 depth figure alone, explicitly tolerating excess depth where neighbouring precedent supports it

· names departures from the established rear building line as creating a 'leapfrogging effect' rather than just citing non-compliance

· distinguishes single-storey and first-floor extension tests explicitly (45-degree line at ground floor vs the DMD11 first-floor criteria) within the same paragraph

What their reports consistently look for

· what this officer's reports consistently look for: whether the proposed extension would maintain a 'subservient appearance' relative to the existing series of buildings on the street

· what this officer's reports consistently look for: a specific, named neighbouring precedent for the proposed extension depth before accepting a departure from DMD11's 3m guideline

· what this officer's reports consistently look for: whether cumulative extension depth (existing plus proposed) would distort the common rear alignment and create a 'leapfrogging effect'

In their own words

The proposal which would result in a cumulative rear extension depth of 10.5m at the rear elevation which includes an infill to the side of the existing outrigger is considered excessive and this would distort the common alignment of rear extensions along this side of the street by creating a `leapfrogging effect', which would have an adverse impact on the character and appearance of both the subject dwelling and the

20/00388/HOU

Given the character typologies of end-of-terrace dwellings within the area having footprints close to the side boundaries, the proposed side extension would maintain a subservient appearance and as a result it would not harmfully unbalance the existing series of buildings or result in a harmful loss of openness in this section of the street
