How they reason — coded from their reports

Harris handles a heritage-weighted caseload including listed-building consent and conservation-area work, and is distinctive for a strict housing-mix preservation stance on section 73 variation applications -- refusing where a proposed change would reduce a previously-approved unit's bedroom count without justification, treating it as a straightforward Policy DM13 non-compliance rather than weighing other benefits. On listed-building-consent applications she opens consistently with the NPPF's heritage-asset 'enjoyed for their contribution to the quality of life' framing before the Section 66/Policy DM12 preservation test.

Observable habits

· on section 73 variation applications, refuses where a change would reduce a previously-approved unit's bedroom count without supporting justification, treated as a standalone Policy DM13 non-compliance

· opens listed-building-consent assessments with a consistent NPPF heritage-asset framing ('conserve heritage assets ... so that they can be enjoyed for their contribution to the quality of life') before the statutory preservation test

· on variation applications, explicitly compares the current proposal's impact against the ALREADY-APPROVED baseline scheme rather than against the pre-existing (unextended) building

What their reports consistently look for

· whether a section 73 variation would reduce a previously-approved unit's bedroom count without justification, triggering a standalone Policy DM13 objection

· the NPPF's 'quality of life' heritage-asset framing and the Section 66/Policy DM12 preservation test for listed-building-consent applications

· the incremental difference between the current variation proposal and the ALREADY-APPROVED baseline scheme, not the original unextended building

In their own words

the proposals would result in the loss of a 3-bed unit and there is no supporting justification provided as to why this 3-bed unit has not been re-provided as part of the proposed scheme. The proposed unit mix would be contrary to Policy DM13 of the Council's Core Strategy

21/02095/FUL

the Council should conserve heritage assets in a manner appropriate to their significance, so that they can be enjoyed for their contribution to the quality of life of this and future generations
