Hi,
If it helps, an easy way to add detail to OSM is with the Street Complete app:
https://streetcomplete.app/

Building detail can only be added as imagery gets released (just added detail from new ESRI and a survey), but Street Complete can add detail almost anywhere.

Thanks again for the edits you have made to make the free map better.
Happy Mapping,

Hi,
Ah - that detail helps, thanks.

A building once confounded me for a month - eventually spotted it was 4x flats with side entrances. Cadastral data doesn't help with housing associations.

I occasionally visit Barry's Bargains on the high street, so might manage a ground survey.
Thanks and Happy Mapping,

James
