How is the "boughton house" described in the novel, On the Banks of Plum Creek?

The boughten house is a house constructed of purchased, or “boughten” supplies like lumber and factory-made hardware, such as hinges. The boughten house is constructed by Pa with Mr. Nelson’s help. The boughten house has two floors and a real tin roof. The upper floor, the attic, serves as a bedroom for Laura and Mary. The lower floor features two rooms. One is a bedroom for Ma and Pa, and the other is a family and common room where chores and cooking are done. Attached to the house is a lean-to, for storage and to help keep out the weather upon entering and leaving the house. The boughten house is essentially a dream house for Laura and her family.
