The Baltimore Sun recently featured a Habitat for Humanity project consisting of nine factory-built homes in Chesapeake, MD.

According to the article:

Factory-built houses aren't just quick to put up, they're cheaper than homes constructed on-site. Advocates for lower-income residents are realizing that, done right, there's nothing of the much-maligned trailer park about houses coming off today's assembly lines.

Interesting to note:

Habitat's modular-home buyers are getting the whole package, land and all, with no-interest loans from the organization. Including pricey site work but not the cost to buy the land, each house cost Habitat $120,000. When the group built homes from scratch last year in Southwest Baltimore, the construction and site work totaled nearly $160,000 per house.

They include a video (1:54) discussing the project.
