Judging by the size of the front door it looks to be an old Faller kit, as they were quite under scale in the old days.
You can find all Fallers city houses here:
FALLER - Wir bauen die Welt im Modell
There are 82 kits in total, so take a look and see if you can find it.
I checked the Kibri catalog, but the building doesn't appear there. Heres a link to their catalog:

I hope it will be helpful... :-)
