The price of a log house or a prefabricated house is based on the quantity of material necessary to build the house, influenced by its size. Therefore, the modification of a house model or personalized plans will not apply a substantial cost increase to the price compared to a home kit. Concretely, a similar personalized plan or a model kit can have similar prices. Likewise, switching the bedroom and kitchen located on a house model won't impact dramatically the final price of the house.
