Heya, thanks for your edits around Ambleside recently :)

I’ve fixed the house type tagging here in https://www.openstreetmap.org/changeset/164386790 — building=terrace is for the outline of an entire row of terraces, not individual houses within a terrace. building=house house=terraced is for that.
