How they reason — coded from their reports

Manceau's caseload spans Belgravia embassy/townhouse casework and larger mixed-use commercial applications, and she consistently tests a new roof terrace or feature against the ESTABLISHED PATTERN of similar terraces already present on the same mews or square, treating consistency with that pattern (and a matching set-back distance) as the basis for accepting a new proposal even where mutual overlooking would result. On amended S.73/minor-material schemes she cross-references conditions from the ORIGINAL permission individually to confirm whether each remains appropriate given specific proposed changes (e.g. customer-number conditions, plant-noise conditions).

Observable habits

· tests a new roof terrace/feature against the established pattern of similar features already present on the same mews or square, including matching set-back distances, as the basis for acceptance

· accepts that mutual overlooking between neighbouring roof terraces/rear windows is an inherent and acceptable feature of a mews context rather than a fresh harm to be avoided

· cross-references each individual condition from an ORIGINAL permission (customer numbers, plant noise limits) to determine whether it remains appropriate given the specific proposed amendment

What their reports consistently look for

· what this officer's reports consistently look for: whether a new terrace/feature matches an established pattern (including set-back distance) of similar features already present nearby

· what this officer's reports consistently look for: whether mutual overlooking between neighbouring terraces is an accepted, inherent feature of the local context

· what this officer's reports consistently look for: each individual condition from an original permission, checked one by one against a proposed amendment rather than reviewed as a block

In their own words

Given the prevailing context of roof terraces in the mews, including some reasonably recent permissions, terraces such as that proposed now form part of the established character of this part of Eaton Mews South

20/03335/FULL

Condition 8 of the original permission states: "You must not allow more than 114 customers in the basement bar, 34 customers in the 7th floor bar and 90 customers on the roof terrace at any one time."

20/01844/FULL
