/diy/ - Do It Yourself

i gotta question. was gonna make a thread but since this is here. i dont want one of these houses on wheels. i want a legit small home. like 16x30ft 2 floor or lofted. im aware i could build this myself or hire some mexicans to do it once its designed but there are these prefab "sheds" that can be converted to homes pretty easily. is it worth looking into the prefabs or should i just start pricing out and planning to frame it up myself? id really rather not have to do the outer walls, flooring, and roofing
