Quick Answer
The cheapest small house plans are simple, efficient, and easy to build.
Look for compact layouts with simple footprints, simple rooflines, practical room sizes, standard materials, and limited custom details. Avoid choosing a plan only because it is small; complexity can make a small home surprisingly expensive.
