Tee,

It's best to use the EMF newsgroup for questions about EMF's core 
frameworks.  I've added it to the "to" list of the reply.

There was a very similar question to this on the EMF newsgroup just 
yesterday.  You might want to have a look at the thread "containment or 
reference -> consequences in generated Editor commands"

You'd need to create an instance of Type in a separate resource where it 
would be the root object of the resource.  Then in the resource for the 
House, you could use Load Resource... to load the resource that defines 
a/the type.  Once loaded, you'd be able to refer to that Type in the 
properties view for the House.
