Traditional Nuxalk houses were typical Northwest Coast rectangular cedar plank houses, with a gabled roof supported on two roof beams and a central firepit. Houses were often built on stilts with the front opening to a boardwalk to accommodate the riverbank slopes, flooding and in defense of attacks by raiding parties. The houses of nobles and hereditary chiefs were larger than those of commoners, ranging from 40 feet by 60 feet and upwards, compared to around 15 feet by 30 feet for lower ranking households. In some cases there is a frontal pole through which the entrance is cut, but more often than not, the entrance is a simple doorway.
The Nuxalk carving style is expressed mainly in masks and monumental sculpture. It is most familiar to that of the Kwakwaka’wakw and Northern Wakashans but it is distinctive and easily recognized for the rounded form of the face. Surface paintings consist of solid U-forms both following and crossing strongly defined intersections of carved planes. The Nuxalk also carved and painted boxes, dishes, benches, spoons and combs.
