Hello,

This comment would have been preferably left on the note where the problem was discussed instead of here.  Reference to the note was provided in the source of the changeset.

However, to me it looks like the request in the note was correct, and the part built in 1930 by architects Michel Polak and René Théry is only the old part (a square).

So, if Electrobel HQ applies to the whole building, an elegant solution might be to only move the wikidata and wikipedia tag to the whole building structure, while retaining the architect/start_date/url tags to way 1245227930.
