Coming in late to this, I have to say I LOVE this model! It's awesome and I can see lots of uses for it! Especially with a rusty/decauing texture on it :D

As Johnnybode said, simply uncheck Smooth Polygons on your object (you can do it at rendertime too but it's better to disable it on the offending model, that way people can render PEOPLE with smoothing (which looks best) and the model without. 

Once you get it made into a PP2 or CR2 (I'd suggest CR2 because that'll take MAT poses, but anything will work) It's easy to "hack" the file and set Smooth = 0 inside the file, turning the bloating off for good!

Hotel rooms were mentioned, and sure those would probably sell, but there is an abundance of those already while this is something rather unique! It's not even what I usually render, but I know I WANT this based on these test renders. And that's saying something!
