Planning appeal decision
4 Thorley High, Thorley, Bishops Stortford, Hertfordshire, CM23 4AR
Planning appeal 3339742 at 4 Thorley High, Thorley, Bishops Stortford, Hertfordshire, CM23 4AR (East Hertfordshire District Council) was dismissed on 6 August 2024 by Inspector Cheesley J, by written representations. The main issue, as the Inspector framed it: whether the proposal would amount to inappropriate development in the Green Belt, having regard to the National Planning Policy Framework and any relevant development plan policies, and if so, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations, so as to amount to the very special circumstances necessary to justify the proposal.
demolish existing PC garage and replace with two-storey side extension at same overall width. Demolish existing brick-built utility annexe to rear of existing house. Construct full width rear single-storey extension with extents and sloping roof in plane of similar extension to adjacent adjoining property (semi-detached)

Main issues, as the Inspector framed them
- whether the proposal would amount to inappropriate development in the Green Belt, having regard to the National Planning Policy Framework and any relevant development plan policies, and if so, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations, so as to amount to the very special circumstances necessary to justify the proposal
- the effect of the proposal on the openness of the Green Belt
What decided it
The scale of the proposed extensions would constitute a disproportionate addition to the original dwelling and would significantly diminish the openness of the Green Belt, with no material considerations amounting to very special circumstances to justify the inappropriate development.
What the Inspector cited
- Development plan policies
- Policy GBR1
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.
