Can cob houses be built in cold climates?
When you think about cob, you need to kind of think about it not having any insulation value at all. So technically, there’s about an R3 insulation value for a foot thick wall of cob. These are just concrete walls and people are fine in these buildings in cold climates. You just need a heat source inside.
How long does it take to build cob house?

Are cob houses cheap to build?
A: Cob building can be extremely inexpensive if you do it yourself. The materials for the walls are very cheap. However, keep in mind that walls are only a small cost of any building: foundations, roofs, windows, doors, floors, finishes, cabinetry and so on are typically a much higher portion of the cost.
