No, that's not correct. The "admin_centre" must be a _place node_
never a building.

In particular, if you do put a building in there which happens to
be a OSM way then you will rightfully find that this building now
represents a hole in your city (multipolygon).

For example, if you look closely, you'll see that Leverett town hall

has a boundary around itself coming from this relation
