Interlock House by Iowa State University

Another Solar Decathlon 2009 team: Iowa State University.

According to the project manager, Interlock House:

[is] a modular construction, with five different components of the house.

There will be three floor components, two of them having walls, one of them having pop-up walls on site...[it] will also have a top portion with two east and west roof modules and a center portion also assembled on site.

...

So we have the east and west parts [of] the house built ahead of time and the center part built on site with pre-cut and pre-fabricated materials.
