Assume you want a house. If you build a new one, the cost of the work is normal to have +100% of the initial cost estimate at the end of the work, and it is likely that the time frame is overrun.
In addition, the quality of the work is hardly predictable even if you hire the same staff who have done previous jobs. Surprisingly, it seems that enormously complex projects, such as the construction of nuclear power plants, have the same weaknesses that seem inherent in the construction industry at this point. One of the main causes is the reduced predictability of events at the construction site due to limited control in an open environment such as the construction site.

For nuclear power plants, they are trying to solve the problem through Small Modular Reactors: they do as much as possible in the factory, a controlled environment, and as little as possible on the construction site, a less controllable environment. It's about moving from an economy of series to an economy of series.
Serial economics applied to residential construction could reduce that average +100% cost increase over estimates that goes to eat up lifetime accumulated incomes, or mortgage the future of generations struggling to return to a normal life for what? To pay for the inefficiency of a specific sector.
There are several prefab solutions, I focus on this one:
