How they reason — coded from their reports

Purnell's caseload is dominated by roof extensions, terraces and outbuildings, and she is distinctive for framing amenity impact between two comparably-affected neighbouring properties as 'mutual and negligible' (echoing a habit also seen in a colleague's reports), and for treating the historic establishment of a terrace's use and size under its own prior application reference as removing any additional noise/overlooking concern from a later, related application (e.g. adding a balustrade to an already-approved terrace). She is precise about citing multiple neighbouring precedent addresses with their own application references when justifying a design departure such as a raised ridge height or additional floor.

Observable habits

· frames amenity impact between an outbuilding or extension and a comparably-affected neighbouring property as both 'mutual and negligible', rather than treating any infringement as one-sided harm

· treats a terrace's use and size as having already been established under its own prior application reference, such that a later related application (e.g. a balustrade change) would create no additional noise or overlooking impact

· cites multiple neighbouring precedent addresses with their own historic application references to justify a design departure such as a raised ridge height, an additional floor, or a full-depth roof extension

What their reports consistently look for

· whether the harm from an outbuilding or extension to a specific affected neighbour is mutual and negligible given that neighbour's own equivalent feature

· whether a terrace's use and size were already established under a prior application reference, removing any additional noise/overlooking concern from later related works

· whether multiple (not just one) named neighbouring addresses with their own historic references establish a pattern justifying a ridge-height increase or additional floor

In their own words

the affected property, No.42 Ellerby Street, possesses an outbuilding of a similar height and scale. As such, harm is considered to be both mutual and negligible.

2020/01845/FUL

The use of the terrace has been established under application ref: 2016/04520/FUL, therefore no additional impact on noise disturbance, from the installation of the railings proposed within this application is anticipated.

2020/00648/FUL
