Main issues, as the Inspector framed them

Whether the proposal would preserve or enhance the character or appearance of The Boltons Conservation Area

What decided it

The replacement building at 5a, with its large scale and flamboyant mansard design, would harm the character and appearance of the conservation area, and the public benefits of the proposal do not outweigh this heritage harm.

Framework references: 205, 208

Plan policies cited: CL1, CL2, CL3, CL6, CL9, CL11

What an account adds

Draw a red line around your site and the appraisal follows.

Heritage. Listed buildings by grade and distance, conservation areas, scheduled monuments, registered parks and gardens, heritage at risk.
Landscape and environment. Green belt, national parks and national landscapes, SSSIs, ancient woodland, SPA, SAC and Ramsar sites, nutrient catchments.
Flooding. Flood zones 2 and 3, surface water, and both again with climate change.
Transport. The 800 metre station catchment and service frequency, bus stops with their weekday frequency, the cycle network, and the Framework’s transport tests measured for the site.

Then the development plan position, the housing land supply as an Inspector last accepted it, and every appeal decided around the site with its letter.

Every English appeal since 2016, with the letter behind it wherever the Inspectorate published one. Searched by meaning as well as by words, with the key case law counted live across the letters.

Casework that chases the deadlines. Applications, appeals and conditions with their statutory dates.

The judgement stays yours. The tool gathers the material and dates it.
