New UNASUR HQ is a Museum

Evo Morales opened a new headquarters for UNASUR in Cochabamba. He called it the "big house of South America," which doesn't make much sense to me, so I wonder if there is a cultural reference with which I am unfamiliar.

At this point, the building is essentially a museum of dreams that could never quite come true. Argentina, Brazil, Chile, Colombia, Paraguay, and Peru all temporarily withdrew (which the TeleSur article conveniently omits), then Colombia decided that would be permanent, while Ecuador's President Lenín Moreno took away its building and turned it into an indigenous university.

This only leaves Bolivia, Guyana, Suriname, Uruguay, and Venezuela. As houses go, that's not very big, and one of the rooms is burning down.
