If this is too big an edit, I have no problem with you reverting this and asking me to drop it to smaller chunks. I downloaded the region I was editing, searched for building=yes, then removed places that didn't look like houses (or were outside the residential regions) and then set building=house. This is because I like to get house numbers via StreetComplete and when I walked around here, everything was building=yes and I couldn't add any information.
