It may well be an abstract object, but it's not a geographical one so it 
doesn't belong in OSM. Relations are a way of linking one geographical 
feature to another for some geographical reason -- part of the same 
long-distance route, or opposite banks of a waterway for example. In 
this case there's no geographical link between two buildings from the 
same architect -- you could just as easily say that all buildings 
belonging to one company should be part of a relation, but that too 
would essentially be categorisation.
