Main issues, as the Inspector framed them

Whether the development preserves or enhances the character or appearance of the designated heritage assets which are Canons Park Estate Conservation Area and the Grade II Listed Historic Park and Garden at Canons Park

What decided it

The incongruous appearance of the portacabin and mixed materials (perspex, wood, metal) in a domestic setting within a conservation area and historic park and garden designation results in unacceptable harm to the significance of the designated heritage assets which cannot be outweighed by any identified public benefits.

Framework references: 199, 202

Plan policies cited: Policy DM7, Policy DM1, Policy D3.D (11), Policy D3.D.(1)

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.
