How they reason — coded from their reports

Yang's corpus includes a notable share of Permission in Principle (PIP) applications and she runs a distinctive, structured windfall-site test explicitly separating 'Location of Development' from 'Land Use Proposed' and 'Amount of Development Proposed', citing NPPF paragraphs by number alongside the specific Croydon windfall housing target (10,060 homes on windfall sites). She is precise about relaying named consultee (Transport Officer, Tree Officer) objections verbatim into the report rather than paraphrasing, and treats those formal objections as carrying independent weight in the recommendation.

Observable habits

· on Permission in Principle applications, runs a structured three-part test (Location of Development / Land Use Proposed / Amount of Development Proposed) each under its own heading, citing specific NPPF paragraph numbers (68, 117, 123) rather than a general windfall-housing statement

· relays a named consultee's (Transport Officer, Tree Officer) objection close to verbatim, including the specific technical reasoning given, rather than summarising it as a bare 'objection received'

· explicitly notes when a scheme's parking-stress survey methodology was independently recalculated or challenged by the Council's own Transport Officer, distinguishing the applicant's figures from the Council's corrected ones

What their reports consistently look for

· a structured Location/Land Use/Amount-of-Development test for PIP applications with specific NPPF paragraph citations

· the exact technical reasoning given by a named consultee's objection, not a summarised restatement

· whether a parking-stress survey's methodology and site coverage was validated or corrected by the Council's own Transport Officer

In their own words

Council's Officer advised that we would not have wanted Bridle Road to be included in the survey and the parking stress results were recalculated without the spaces shown on that road

It should be noted that the support for the location of development expressed above does not indicate support, or otherwise, for the proposed layout of buildings within the plot or the type and form of housing proposed
