How they reason — coded from their reports

Lavelle's Mayfair/Central CAZ caseload covers listed-building consent, retail change of use, and commercial extensions, and he is particularly rigorous about the general rule that roof extensions on mansard-roofed buildings are 'ordinarily unacceptable' as completed compositions, only departing from it where a specific applicant demonstration (limited visibility from named viewpoints, a set-back railing) proves the exception applies. On retail-loss applications he requires concrete marketing evidence (named agents, asking rents, specific interested-party names) before accepting that a unit is genuinely unviable for its protected use.

Observable habits

· starts from the general design principle that roof extensions on mansard roofs are 'ordinarily unacceptable' as completed architectural compositions, and requires the applicant to demonstrate a specific exception (limited visibility from named viewpoints) before departing from it

· on retail-loss applications, requires concrete marketing evidence (named agent, specific asking rent, named interested parties who did not proceed) before accepting a unit is genuinely unviable for its protected A1 use

· notes when a condition from an original permission has ALREADY been discharged/complied with and is therefore no longer necessary to re-impose on a related application

What their reports consistently look for

· what this officer's reports consistently look for: a specific demonstrated exception (limited visibility from named viewpoints) before departing from the general 'mansard roofs are complete compositions' design principle

· what this officer's reports consistently look for: concrete marketing evidence (named agent, asking rent, named interested non-proceeding parties) before accepting a retail unit is genuinely unviable

· what this officer's reports consistently look for: whether a condition from an original permission has already been discharged, avoiding unnecessary re-imposition

In their own words

Ordinarily, roof extensions are considered to be unacceptable on top of mansard roofs. This is because buildings with these roofs are considered to be completed compositions
