I'm not sure if this is the same as a duplex, because my reading of that suggests that this refers to any building containing two dwellings.

Yes, that's sort-of true. The general idea of a duplex is that it appears to be a single-family house at a glance, but it actually contains two separate dwellings. It also, generally, is owned as a whole by a single owner, not each side owned separately.

But, regardless, we weren't (well, I wasn't, anyway) even familiar with the general term "semi-detached house". So "two-family dwelling" is probably as far as we needed to go. Although Mr. Boxer did say that DeGaulle owned one, and my understanding of the terminology is that that means that he owned one dwelling, not the entire building.
