This is extremely common in the Netherlands. Also very well sorted out these days. My parents' company used to assemble these. A specialised contractor digs and pours a concrete foundation for the walls and once those would be cured a crane, a loader truck and a crew of maybe 3-6 people would on average have a new house ready every 3 days (walls, floors, roofs, wiring, piping), 'ready' being very close to how they're sold to individual owners.

A prefab house design will typically be replicated in several projects / cities, usually with a few customisation options. Different prefab factories have different levels of standardisation and automation. The prefab production lines I designed long ago for example used fully parametric designs to offer standard concepts sized to fit. At the time (~10-15 years ago) a novelty, by now must be pretty standard.

Sounds really interesting.

Do you have any links to learn more about your prefab designs and a company that assembles these designs?

Not in the Netherlands but in Sweden one of the biggest house makers is Älvsbyhus, you can select a base model (begin by selecting number of floors/layout, then size) and customize colors and some details online.
