How they reason — coded from their reports

Pollock's reports lean on specific BRE daylight/sunlight test numbers (VSC percentages, daylight distribution results) laid out window-by-window, and he distinguishes primary from secondary windows when a test fails. He works through neighbour objections under named sub-headings (Party Wall, Overshadowing, Overlooking, Other Issues) rather than folding them into a single amenity paragraph.

Observable habits

· sets out individual VSC/daylight-distribution figures per window before drawing a conclusion

· separates overshadowing, over-dominance and overlooking into distinct labelled sub-sections rather than one amenity paragraph

· explicitly addresses non-planning objections (Party Wall Act, cumulative impact from a neighbouring Certificate of Lawfulness) to explain why they are or are not material

What their reports consistently look for

· what this officer's reports consistently look for: numerical BRE daylight/sunlight evidence broken down by individual window, not just a summary conclusion

· what this officer's reports consistently look for: whether a roof extension matches the traditional materials/profile of the specific terrace it sits in

· what this officer's reports consistently look for: separate treatment of each neighbour amenity concern (overlooking, overshadowing, over-dominance) rather than a blended assessment

In their own words

Officers acknowledge that 2 windows facing onto the extension and serving the kitchen of No 40 would fail the VSC test. Whilst this is regrettable, these windows are located on the flank wall and represent secondary windows

P2022/2470/FUL

BRE Guidelines states 'Recommended privacy distances are usually less than this but vary widely, typically from 18 m up to 35 m.' at 25m and 32m away from the windows of the property to the rear the proposed development of the mansard is not considered to result in an unacceptable loss of privacy

P2022/2470/FUL

Measured from 90 published Islington officer reports written by this officer, with recited policy boilerplate stripped before any counting. These describe how this officer works and writes — they are not outcome predictions. Every quote is from a named public report.
