Why factory-built homes perform better

A home built outdoors is exposed to rain, heat, and cold from day one. A home built indoors isn't — and that difference shows up in the finished building's energy performance for decades.

Building in a controlled factory means materials stay dry, cuts are precise, and the building envelope goes together tighter than most site builds can manage. A tighter envelope means less air leakage, more consistent insulation, and lower energy bills — the home simply holds its temperature better.

There's an efficiency story on the front end too. Factory building produces less material waste, because offcuts are tracked, reused, and ordered to spec rather than estimated and discarded on a muddy site. Less waste, a tighter home, and lower running costs: the environmental case and the homeowner's case point the same direction.
