Square One Villages (http://www.squareonevillages.org/) is the successor to Opportunity Village and Emerald Village projects in Eugene Oregon. As such it focuses on helping other communities establish similar mini-house communities for the homeless.
Opportunity Village opened in 2013 with 30 minihouses each about 60 – 80 square feet.
Emerald Village is under construction and will provide longer term housing as the next step up from Opportunity Village. The units will be 150 – 200 sq. ft. and include internal plumbing and cooking resources.
