Those trailers seem too small to accomodate anything other than a small project like DVC. There's no way there'd be enough space in there to house all of the Imagineers that would be needed for a large project.
Those are small temporary buildings and they have been there for a little while. I believe they were added about the time the FLE project started. You can see them on Google maps, and Bing.
Sheesh, I would love to call those little buildings my place of employment.
They are bigger than the Fantasyland project offices. So they could certainly be used for a very large project.
Do you know of a project that's larger than FLE that is far enough to warrant trailers?
Could be more than one project around WDW......
