This is the second time this builder is employing this building technique. They're the only ones in Canada that do it. To tell you the truth, I don't even know if there's anyone in the US building their level of homes in this fashion.
By building indoors they can run for almost 24 hours per day, 7 days a week. Regardless of weather outside. Temperature controlled environment also makes for much more comfortable working conditions and in the same amount of work time, more gets done.
The factor y is on site. It's only about 2000 meters (2km) from the location the house is placed on. All "driving" is done on private roads that are part of the community being built. When they're done the whole community they'll disassemble the factory.
Their older factory, in another town, which is built outside of a community was turned into a plant to machine-build sections of wall and floor. Similar robots as used in the auto-industry according to them. Those get delivered daily to this plant and are assembled by the workers. Roof trusses also get delivered and completed roofs are built on the ground and then shingled before being hoisted up onto the house and attached. You can see how much safer this is.
It takes no more than 3 weeks to build and finish the interior of a complete home. Ideally their build rate was supposed to be under 2 weeks.
There must be a story somewhere with the average weight of the homes since the factory has been spotlighted a few times by both local and national media.
Here's someone else's home delivered in December. It features Hardiboard siding applied at the factory instead of brick (installed after the home is dropped).
