Find building by shape

Do you know a tool, whatever to find a bulding if I know the shape of the floor plan?
Maybe it’s possible via Overpass-Turbo. But I was not able to create a query.

If you have problems with the description of my problem, feel free to ask me.

Many Thanks.

Hi justusjonas9, your question sounds like approximal. If you realize that there is only one specific form which w/could match your query, correct ?
IMHO there is no query you could build to find your object in OSM, but if your able to use names or numbers or even a date you might have as being less specific success.
Good Luck
