Derek Sherrell shows a low cost, open source house that he built in 90 days. He is giving away the plans for free for anyone who wants to build their own.
Open source is a wonderful concept that should be applied to everything, not just software.
Architectural blueprints have been explicitly covered by copyright in the US since 1990, but were likely implicitly covered before then.
He could always provide an open-source license before claiming that he is "open sourcing" his designs. You could always check for a license before claiming that something is open-source. Putting the onus on people after the fact to make those previous claims true doesn't make any sense.

If you want a more sustainable option (read: higher density, multi-family housing) that's actually licensed openly, checkout Eco-Libre's designs for the Launch-Nest.
The structure is designed to house 30 people (18 meters x 7 meters, 5-stories high), off-grid solar PV (energy) and thermal (heating, cooking), and walls are made of CEB pressed on-site.
It absolutely can be, and there are plenty of do it yourself plans out there. They just tend to be pretty expensive. It's nice that there's something out there now just completely open.
