With the boundary going through a building and at odds with the rest of
the surrounding elements I would expect an element of tidying up rather
than simply dumping the poor quality OS polygon on top of potentially
more correct data! But that is why I say some element of local knowledge
to tidy up the detail is essential.

Switching to osm and looking, the buildings need reworking anyway but a
correct boundary needs local input ... the OS one is simply wrong.
