It is pretty expensive considering the cost of those items are pretty dang high, especially windows and doors of which numerous windows are custom shapes. Not to mention the labor costs of it all which are not included and are going to cost atleast as much as the materials. So it is closer to 300K for just the framework. I also don't see other things mentioned like roofing material or insulation and the whole thing needs to be painted or finished. The foundation is also a large cost.
