For the German regions of Sachsen-Anhalt and Niedersachen, I thought there are probably all buildings mapped. At least those called Einfamilienhaus or Reihenhaus.
But I found that with the following overPass query, many potential spots for missing buildings data can be found:
way["landuse"="construction"]({{bbox}});
And because of that my change set statistics of today is as follows:
Edited on 2026-01-27:
- 2281 nodes
- 404 ways

Most used tags for nodes:

addr:street(48) -
addr:postcode(46) -

Most used tags for ways:
-

addr:city(9)
Conclusion
Many buildings have been added (and some trees 🌳👼) in Niedersachsen and Sachsen-Anhalt.
But as the query suggests, there are still some construction sites which can be investigated. Probably this “trick” is already known to hardcore-mapper ;)
