How they reason — coded from their reports

Heaney handles multi-unit conversion/extension schemes in the 2025-era checklist format and is willing to conclude that an internal consultee's objection (e.g. SuDS) does not justify refusal where the harm it flags can be resolved by a pre-commencement condition, stating that conclusion explicitly rather than silently overriding the objection.

Observable habits

· explicitly states that an internal consultee objection (e.g. SuDS/drainage) 'could not be justified' as a refusal ground where the concern is addressable by a pre-commencement condition, rather than silently discounting it

· measures a scheme's shortfall against a specific separation-distance policy (DMD10) but reasons through internal layout/orientation to find the shortfall acceptable in the particular circumstances

· for stacking/upward-extension schemes, checks each unit's GIA against its balcony size and depth individually rather than an aggregate space-standards statement

What their reports consistently look for

· what this officer's reports consistently look for: whether an internal consultee's objection (e.g. SuDS) can genuinely be resolved by a pre-commencement condition, explicitly concluding a refusal on that ground 'could not be justified' if so

· what this officer's reports consistently look for: whether a DMD10 separation-distance shortfall is actually harmful given the specific internal layout and orientation of the rooms involved, not the raw distance figure alone

· what this officer's reports consistently look for: each proposed unit's GIA, balcony size and depth checked individually against the London Plan minimum standards

In their own words

Whilst this objection has been noted, the measures required to make this element of the proposal acceptable could be addressed via a pre-commencement planning condition as the development is not located in a Flood Risk Area and is subject to a low surface water flood risk. As such a refusal on these grounds could not be justified

25/00445/FUL

The development would be slightly below the required separation distance required by DMD policy 10. However, given the internal layout and orientation that the building would have in that its rear bedrooms and communal stairwell would be located on its south side. It is not considered there would be any unacceptable overlooking or impact on privacy to these flats

25/00445/FUL

Measured from 107 published Enfield 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.
