Yes, could be. For us, a complete 12 months: building permit submitted 06.18, approved 08.18, existing house demolished 09.18, basement 12.18, house placement 2 days 02.19, move-in 06.19
So with us, they were pretty fast. The building application was submitted at the beginning of December and the approval was received in mid-January. The general contractor started at the end of February and the move is planned for the end of September / October.
Maybe "prefabricated houses" are also included in this average. That would explain the very short average.

We were even faster with solid construction But I stick to it: at least plan 12 months.
