How they reason — coded from their reports

Cooksley cites specific dismissed PLANNING INSPECTORATE APPEALS on comparable roof-terrace refusals in the same conservation area as direct precedent supporting a refusal, and measures the exact separation distance in metres from a proposed terrace balustrade to each affected neighbouring dwelling's front elevation to judge privacy harm. He checks a conservation area's own street-level pattern (which side of a mews already has mansard extensions, which does not) precisely before judging whether a proposed roof extension breaks or extends an established local group.

In their own words

Similar roof terraces to the one proposed have been refused when they have been found to be harmful to the Conservation Area they are located within. Appeals against these refusals have been dismissed by the Planning Inspectorate including at 8 Wilfred Street (ref No. APP/X5990/D/18/3201539)
