I struggle with what to call the <BuildingName> in that example. A recent suggestion for named terraces was to use addr:street=<TerraceName> and addr:parentstreet=<StreetName>, but if the <HouseNumber> relates the whole building to to parentstreet, then reconstructing an address seems impossible.
The closest existing tag seems to be add:housename=<BuildingName>, but I don't know if that stretches the definition too much.
