I'm over a year late in find this article but it is still worth reading.

 

Over email I was thinking about the future of the McMansion as I semi-seriously contemplating moving into one with other economically depressed folks. There are few left who can afford the notes on these monstrosities, and fewer still who would want to live in them. There will likely be a future in cutting these up into duplexes and triplexes just like was done in San Francisco and the east coast to the large houses of the early 20th century when their wealthy inhabitants left to the suburbs.
