PS got it, with a copying, pasting and furtling around. I've given it here as "code" to avoid it being corrupted.

Code:

https://planning.sholland.gov.uk/OcellaWeb/showDocuments?reference=H16-1096-23&module=pl

At first glance, some of the documents referenced in the Design and Access statement may be missing or incomplete. For instance PO4 3899b.
