Main issues, as the Inspector framed them

  • The effect of the single-storey rear extension on the living conditions of the occupiers of 29 Porters Hill in respect of whether or not it would be overbearing

What decided it

The specific site circumstances, including the neighbour's elevated land level, the positioning of its windows and side projection, and the extension's modest height and flat roof, would prevent it appearing overbearing despite exceeding the 3m depth guideline.

What the Inspector cited

Development plan policies
Policy 72 of the St Albans District Local Plan Review 1994

How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
