Here's a local entry to the Solar Decathlon 2009: Team Boston.
From their page on the DOE site:
Team Boston is composed of more than 150 students from Boston Architectural College (BAC) and Tufts University as well as a handful from the Massachusetts Institute of Technology, Harvard University Graduate School of Design, Northeastern University, and Massachusetts College of Art and Design.
The primary form of their Curio.House is an L-module. According to the Curio site:
This L-module adheres dimensionally to standard shipping requirements, and can be developed further into a factory-built, prefabricated seed to be easily shipped to any site.
