Locally we have had a pub and terrace building demolished to give way to flats. Do I just delete the existing buildings, or what is the best practice? |

I would use the landuse=construction like this one http://www.openstreetmap.org/?lat=52.350307&lon=-0.176417&zoom=18&layers=M I used the old pub name then and intend to use a new name if the builders sign it. That way anyone doing a search for it should have a chance of success. 1
If the building is still visible on Bing you can change the building tag to "disused:building=yes" so that other people don't add it again. See the wiki page about the disused key for further information.

To avoid other users recreating it based on memory and/or aerial images I would
It is better than adding demolished=yes that harms data consumers (it is like tagging prison as amenity=hotel + involuntary=yes). It is better than just deleting as it helps mappers relying on aerial images and memory. 1
If a recent edit looks wrong against aerial, but the source is survey or recent visit then either believe the last edit or survey it yourself but not from an armchair. Most aerial is several years old. I have received several and sent one or two messages to mappers when mapping was or seemed to be incorrect so contacting them is a sensible option if in doubt.

Some people prefix the building key with "demolished:" or "razed:". They are known as lifecycle prefix. https://wiki.openstreetmap.org/wiki/Lifecycle_prefix Old version: building=residential, new version: demolished:building=residential.

Yes, it's absolutely ok to delete a demolished building. In fact, that's the default way of dealing with things that no longer exist. If you're worried about people re-mapping the building from outdated imagery, leaving a hint to your fellow mappers can make sense, though. Mapping the construction site often gets the message across, but for additional emphasis, you could leave the original building outline in place with only a Some mappers prefer leaving the old tagging in place, but adding a lifecycle prefix such as |

I'd leave the polygon(s) in place until either new construction is in the area or the satellite imagery is updated to show the area without the buildings. That will keep arm chair mappers from elsewhere from erroneously adding them back in. However they are no longer buildings, so use the lifecycle prefix, see https://wiki.openstreetmap.org/wiki/Comparison_of_life_cycle_concepts#Lifecycle_prefix_.28.3Cstatus.3E:.3Ckey.3E_.3D_.3Cvalue.3E.29 to change the building= tag to demolished:building= This will remove the buildings from maps that render building=* It probably is a good idea to add the note tag as suggested by Mateusz Konieczny as well. |
Thanks very much for this. As the site is now effectively a clear area for some time I have:-
The pub had a long history, so I'd like to see the tag stay as people will refer to it locally for a long time.

This looks like the right thing to do.
As I already explained in a comment below Andy's answer you should use the disused tag. In your case, change "amenity=pub" to "disused:amenity=pub" because it is obviously not a pub anymore.
Have made the change as requested. The disused: prefix to a tag seems to me important for my mapping going forward.
In this case the disused prefix is actually wrong. Disused means the building is still there but no longer used as such. In stead you could do the same with the word "demolished" or simply use a note tag.
You are absolutely right cartinus. The disused tag is only for features that still exist but are currently not in use. If the feature doesn't exist anymore then another prefix or a note should be used.
