Main issues, as the Inspector framed them
- The effect of the proposed mansard roof extension upon the character and appearance of the host building and the greater locality, with special regard given to the character and appearance of the St. John's Wood Conservation Area
- Whether sufficient information has been submitted to demonstrate that the basement extension is made in accordance with the development plan policies
What decided it
The mansard roof extension would lack architectural authenticity and integrity and cause less than substantial harm to the conservation area's significance that was not outweighed by public benefits, contrary to NPPF paragraphs 199-203 and development plan policies; the basement extension was acceptable subject to pre-commencement conditions securing flood risk mitigation measures.
