Ah - thanks! I'd looked in the architecture and trivia sections, but hadn't thought to check under World Heritage Sites on Other Lists. Glad to see it already exists!

As for Dancing House, it is on the right bank of the Vltava River, near Jiraskuv bridge, and as far as I can tell, appears to be within the core zone.

Another addition to the Pritzker Prize connection would be:

Venice and its Lagoon: La Fenice opera house was rebuilt by architect Aldo Rossi (1990)

You can just go to the Connections homepage and search the word "Pritzker" in the little grey dropdown box called Connections almost at the top

Now I know — that will help with searching. Thanks!
