The Nooksack people lived in large plank houses made of cedar. These houses were typically rectangular in shape and could be up to 100 feet long and 50 feet wide. They were constructed with a framework of heavy beams, which were then covered with planks of cedar. The roofs were also made of cedar planks and were slanted to allow for drainage. The floors of the houses were covered with mats of cedar bark or animal skins.
The interior of a plank house was typically divided into several rooms, including a main living area, a sleeping area, and a cooking area. The main living area was usually located in the center of the house and was used for activities such as eating, socializing, and dancing. The sleeping area was typically located at the back of the house and was divided into several smaller rooms. Each family had its own sleeping room. The cooking area was usually located near the entrance of the house and was used for preparing meals.
Plank houses were well-suited to the climate of the Pacific Northwest. They were warm and dry in the winter and cool and airy in the summer. They were also very durable and could withstand the strong winds and heavy rains of the region.
