I think the notion that "one offs" increase cost is really not nearly as big of an added cost as the article makes it out to be. I've worked on building homes and monitored the process quite a few times and while it might look chaotic to someone who doesn't build stuff the guys who do it for a living are very efficient. And the notion that homes should be mass produced from a template sounds awful to me. I think where we've blown it with home design really began in the `80s with the boom of "McMansions". They're expensive to maintain and very inefficient. In the past decade I've seen some very cool smaller home designs (as well as "tiny" homes) so, personally, I think we're doing a lot better now than we were 20-40 years ago.
