Main issues, as the Inspector framed them
- Whether the Council's decision was well-founded, turning on whether the proposal amounted to 'development' as defined by section 55 of the Town and Country Planning Act 1990
What decided it
The amalgamation would result in a material change of use because it would reduce the number of residential units and thereby affect the Council's ability to meet its housing targets, a recognised planning objective, and no relevant permitted development rights applied.
What the Inspector cited
- Development plan policies
- Policy HO1Policy CH1
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.
