Main issues, as the Inspector framed them
- Whether the conditions are reasonable and necessary in the interests of protecting the living conditions of neighbouring occupiers
What decided it
The new dwelling's larger windows and elevated balconies would create unacceptable levels of overlooking to the neighbouring property's rear windows and garden that would not be mitigated without the obscure glazing, non-opening restrictions, and privacy screens required by the conditions.

- Development plan policies
- Policy 12 of the Cornwall Local Plan Strategic Policies 2010-2030Policy SEC1 of the Climate Emergency DPD
- National Planning Policy Framework
- Paragraph 56Paragraph 57Paragraph 135
