Hi. I'm an ecological design student working on a project for a proposed affordable housing development in Western Ma. I'm trying to help the town site and build their new development in the most environmentally sensitive, low-impact way possible. The town is interested in the idea of using prefab, modular houses, so I was wondering if anyone had any ideas of any very affordable green prefab houses that would be appropriate for the Northeast (or any other tips). We're probably going to get solar panels donated, so that's a good start.
