text: @Spezialist: Are you sure that a housenumber is missing here? In NRW Atlas this is light gray - which means "additional building" (not a main building with address - dark gray). And in aerial imagery it looks like it's associated to 144, they share the same property and courtyard entrance. It also does not look like a classic "house" in satellite view (but this is only a vague assumption). Could you please answer us the result?
