Main issues, as the Inspector framed them
- Whether the proposal represents permitted development under Schedule 2, Part 3, Class O of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended), having particular regard to the impacts of noise from commercial premises on the intended occupiers of the development
What decided it
The absence of site-specific noise survey data in a highly noise-sensitive location bounded by night-time economy uses meant the Inspector could not be certain that the proposed mitigation would reduce noise to an acceptable level, failing the Class O permitted development test.
What the Inspector cited
- Development plan policies
- Policy PCS23 of the Portsmouth Plan (2012)
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.
