When and why did the Haudenosaunee transition from longhouses to individual dwellings?

• A. Population growth required smaller dwellings
• B. A fashion trend favored new architecture
• C. An invitation from allies prompted change
• D. New kinds of materials for building homes became available

Answer: (D)

Material availability drives changes in housing forms. Haudenosaunee longhouses were multi-family structures built from local timber and bark. When new materials—brought through contact with Europeans, like ready-made boards, nails, and other construction tools—became available, builders could set up separate, single-family dwellings instead of extending a single longhouse. This access to different building techniques and materials made independent homes feasible while still within the village context. The other options don’t fit because population pressure would push toward larger spaces, not smaller ones; a fashion trend isn’t a lasting architectural force; and alliances wouldn’t by themselves supply the materials needed for a new housing form.
