A lot of hype has surrounded pre-fabricated housing lately. From IKEA's venture into mass-produced homes to Dwell Magazine's most recent issue dedicated to it, it is quickly becoming a lower cost alternative to building your first modern home from scratch. As another (and to me, preferred) option to the condoliths (as coined by Andrew) that are spreading all over the city, you may want to look into it. Fortunately, The Field Museum think it's important too and has a temporary exhibit about it called "Design Innovations in Manufactured Housing."
