After having a tough time finding a builder in Brisbane to build a 80m2 dwelling (quotes are coming (130-160k for a shoddy finish with all corners cut) im considering relocatable or prefab homes. Just wondering with these home who is the builder? Is a licensed builder even required? If not am i required to get a owner builder license? Even if my scope of the works under 11k (QLD - just need to connect water/electricity to mains and stairs) Anyone done one in the past?
