This is their only 2-car garage. It is $20,769 plus shipping.
This is one of their larger homes, 1,767 square feet and two stories, but without a staircase. That is extra. It comes with "a retractable pull down loft ladder." Right now it is on sale for $42,999. They say that it is usually $65,725.
They do not use drywall, they have wood boards inside.
They also offer an extra insulation kit for 10% more. The walls are R12, the kit adds R13, but they say that makes R27.
Right.
Math.
I did not see any homes with an attached garage.
