How they reason — coded from their reports

Hollington's large mixed-use scheme reports fix precise condition wording defects — a public art condition with 'no trigger for when...it is provided at all' — and propose specific redrafted wording rather than accepting vague obligations. He explicitly credits a scheme's negotiation history where 'many of the harmful and negative features' (a lift enclosure, ceiling removal) have been removed through consultation with an amenity society, treating the surviving proposal as a 'reasonable compromise'.

Observable habits

· identifies precise defects in approved condition wording (no trigger for delivery, no requirement that a benefit is ever actually provided) and proposes specific redrafted wording to fix them

· credits a scheme's negotiation history explicitly, listing the specific harmful features removed through consultation with a named amenity society as evidence the surviving proposal is a 'reasonable compromise'

· on refusals of clear glazing/overlooking schemes, cross-references SPECIFIC pre-existing conditions from a related permission (obscure glazing requirements, a terrace-use restriction) that the current application would breach

What their reports consistently look for

· what this officer's reports consistently look for: whether a condition's wording actually has a trigger requiring the benefit to be delivered, not just referenced

· what this officer's reports consistently look for: the specific harmful features removed from a scheme through consultation with a named amenity society

· what this officer's reports consistently look for: whether a new proposal would breach a specific pre-existing condition (obscure glazing, terrace-use restriction) from a related permission on the same site

In their own words

This wording needs amending as there is currently no trigger for when the public art needs to be provided or, indeed, whether it is provided at all

20/03987/FULL

The current proposals represent heavily negotiated position and many of the harmful and negative features and been removed from the scheme. These include the rear lift enclose, removal of roof and ceilings of 21b Devonshire Street
