- Moving homebuilding into factories has rarely produced big cost cuts compared to traditional on‑site building; most savings are modest (often 5–20%) and can vanish once site work and finishing are counted, with manufactured single‑wide homes being the main outlier.
- Prefabrication’s main practical benefits are faster schedules, tighter quality control, and more predictable budgets and timelines, not large long‑term price reductions.
- True industrial gains in housing require deeper changes than simply building in a factory — transport, codes, customization, and the need for new standardized processes limit how much prefab alone can lower costs.
