It has to be called the pure "installation phase," because construction actually starts much earlier in the factory.
The production of our house started 1 week before the installation date!
Yes and no, the interior finishing of the prefabricated house, as carried out by our provider, can be completely done in 4-5 weeks.
Because no screed was poured, but prefabricated screed parts were placed in the rooms with a crane.
Then the windows are already pre-assembled.
Additionally, our prefabricated house provider offers plastering of the exterior walls at the factory.
Only the corners were plastered and painted on site.
So theoretically, if you count the planning up to sample selection, it was about 3 months.
Planning and waiting for the building permit took about 8 months.
