- Whether the appeal scheme preserves the Grade II* listed building of Frognal Grove including former stable range, or any features of special architectural or historic interest which it possesses, and whether the proposal preserves or enhances the character or appearance of the Hampstead Conservation Area and, as such, whether the conditions imposed on planning permission Ref 2021/3072/P and listed building consent Ref 2021/3075/L continue to serve a useful purpose.
What decided it
The as-built roof alterations caused a high level of less than substantial harm to the listed building and conservation area which the moderate public benefits did not outweigh.
The moderate weight of public benefits (heritage improvements, thermal performance, fire safety, improved breathability) did not outweigh the considerable weight attached to the less than substantial harm caused to the significance of the listed building and conservation area.
