Main issues, as the Inspector framed them

The effect of the revised roof form on the living conditions of the occupiers of the upper floor room at No.14 Wilberforce Road, with particular regard to outlook and light

What decided it

The major adverse reduction in sunlight and loss of outlook from the principal window of the neighbouring property would result in unacceptable harm to living conditions, conflicting with Policy PCS23 and NPPF paragraph 135.

Framework references: 135

Plan policies cited: Policy PCS23 of The Portsmouth Plan (2012), Emerging Policy PLP1 of the Portsmouth Local Plan (2024)

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.
