How they reason — coded from their reports

Mielczarek's caseload is dominated by first-floor and rear roof 'pod' extensions and he applies a numeric '15% angle of unobscured/unobstructed visibility' test alongside the standard 45-degree test for first-floor back-addition enlargements, calculating the specific depth and width against this threshold rather than a bare pass/fail. Where a first-floor rear extension formally infringes a criterion, he is comfortable finding it acceptable by pointing to an existing conservatory or extension established on the site for many years under its own historic reference, treating the historic baseline as the comparator rather than a hypothetical compliant scheme. He is one of the more willing officers to refuse where a rear roof extension's depth clearly exceeds the Council's 50% preferred design threshold and visibly dominates neighbouring windows, distinguishing genuine departures from cases where non-compliant neighbouring precedents were themselves built contrary to their approved drawings.

Observable habits

· applies a numeric '15% angle of unobscured/unobstructed visibility' calculation to first-floor back-addition width/depth increases, in addition to the standard 45-degree rear-boundary test

· where a first-floor rear extension technically infringes a criterion, compares it to an existing conservatory or extension already established on the site for many years under its own historic application reference, rather than a hypothetical fully-compliant scheme

· distinguishes between genuine neighbouring precedent and precedent that was itself built contrary to its approved drawings, refusing to treat unlawful over-depth extensions elsewhere in the terrace as a valid comparator

What their reports consistently look for

· whether a first-floor back-addition enlargement falls within the 15% angle of unobscured visibility as well as the 45-degree rear-boundary test

· whether a technically non-compliant rear extension replicates the dimensions of an existing conservatory or addition already established on the site under its own historic reference

· whether a cited neighbouring 'precedent' extension was itself lawfully approved at that depth, or built contrary to its own approved drawings

In their own words

the proposed extension would replicate similar dimensions of the existing conservatory which has been established on the site for many years (1993/00122/FUL)

2020/00286/FUL

it should be noted that these extensions were constructed contrary to the originally approved drawings that required rear extensions with a depth no greater than 50% of the back ad

2020/00592/FUL
