How they reason — coded from their reports

Flaherty handles Kingston's major residential schemes (10+ units) and is distinctive for engaging directly with viability assessments -- naming the specific affordable-housing shortfall figure claimed by the applicant's viability assessor and the independent assessor's counter-conclusion -- and for a rigorous daylight/sunlight Average Daylight Factor (ADF) analysis citing exact BRE Guidance figures per room rather than a general finding. He applies the NPPF 'tilted balance' test explicitly where the Council cannot demonstrate a five-year housing land supply, and has a comparatively higher refusal comfort on major schemes where housing mix or heritage harm cannot be resolved through negotiation.

Observable habits

· engages directly with submitted viability assessments, naming the specific affordable-housing shortfall figure claimed and the independent viability assessor's counter-conclusion rather than accepting either at face value

· runs a room-by-room Average Daylight Factor (ADF) analysis against exact BRE Guidance figures for major residential schemes, rather than a general daylight/sunlight finding

· explicitly invokes the NPPF 'tilted balance' (paragraph 11(d)) where the Council cannot demonstrate a five-year housing land supply, naming the specific policies found out-of-date as a result

What their reports consistently look for

· the specific affordable-housing shortfall or provision figure claimed by the applicant's viability assessor, tested against an independent assessor's review

· room-by-room Average Daylight Factor compliance against exact BRE Guidance thresholds (1.5 for living/kitchen/dining rooms, 1.0 for bedrooms)

· whether the NPPF 'tilted balance' applies because the Council cannot demonstrate a five-year housing land supply, and which specific policies are rendered out-of-date as a result

In their own words

An independent Viability Assessor has reviewed the submitted Viability Assessment and, following the submission of additional information from the applicant's Viability Assessors in response to queries raised, has concluded that the scheme could viably provide 6 affordable dwellings on site

20/03091/FUL

it is set out that the Living Rooms would achieve ADF of 1.6 and 1.9 and that Bedrooms would achieve an ADF of 1.9
