Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
What decided it
The alterations do not amount to disproportionate additions over and above the size of the original dwelling, as much of the increase in floor area is associated with first-floor use rather than spatial increase, and the development would not adversely affect the character of the area or the openness of the Green Belt.
What the Inspector cited
- Development plan policies
- GB1GB10
- National Planning Policy Framework
- Paragraph 154
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.
