How they reason — coded from their reports

Borden's caseload is Belgravia/St James's listed-building repair and fabric-sensitive alteration work, and her most distinctive habit is managing genuine uncertainty about hidden fabric condition through carefully worded amending conditions rather than requiring full pre-determination investigation. Where a door, step or wall's underlying condition can't yet be assessed, she sets a conditional test (retain and repair if sound; replace only if proven beyond repair) rather than approving replacement outright or refusing pending more information. She tracks a flat's specific historic-use continuity (using her own records to confirm a flat has been residential since a specific year) as evidence for how much weight to give its surviving plan form, and consistently records design elements removed or altered following officer advice during the application.

Observable habits

· where hidden fabric condition is genuinely unknown, imposes a conditional test (retain/repair if sound, replace only if proven beyond repair) rather than approving outright or requiring pre-determination investigation

· checks the Council's own historic records for a specific unit's use continuity (e.g. confirming a flat has been residential since a stated year) as evidence for the weight given to surviving plan form

· itemises exactly which elements of an original submission were removed or altered following officer advice, distinguishing the revised scheme from the original

· declines double glazing for fanlights/historic glazing even where the applicant has agreed to a laminated-glazing compromise condition, treating it as the accepted middle ground rather than the ideal

What their reports consistently look for

· what this officer's reports consistently look for: whether a fabric element's condition is actually known yet, imposing a conditional retain-or-replace test where it is not

· what this officer's reports consistently look for: the Council's own historic record of a specific unit's use continuity, not just the applicant's account

· what this officer's reports consistently look for: precisely which elements of the original submission changed following officer advice during the application

In their own words

Prior to allowing full replacement of the door and frame, we would need to see it is in poor condition (not suitable for part-retention and use of traditional joinery repair methods). We have secured this through an amending condition

20/01398/LBC

Although other parts of the building were in other uses and/or open plan for periods of time, our records indicate that flat 44 (and the flats above and below it) have been flats since 1897.

20/01494/FULL

The proposals originally included extensive internal works including the demolition of what appear to be original partitions which would have resulted in the loss of the traditional plan form. Also the installation of a sprinkler/mist system. Following officer advice, these works have been omitted

Measured from 301 published Westminster 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.
