Walai

Walai is a term used in some Austronesian languages of Borneo to denote a traditional residential structure associated with Dayak and related Indigenous groups in Kalimantan (Indonesia) and Sarawak (Malaysia). The walai is typically a raised wooden building forming part of a multi-member longhouse complex and is used as the main living and social space for a family or lineage. Architecture varies, but walai structures are commonly built on stilts and oriented to maximize airflow and ventilation in tropical environments. A central corridor or living area may connect several chambers or rooms that are assigned to different family sublineages; the unit is designed to accommodate daily life as well as ceremonies, gatherings, and hospitality.

Socially, the walai functions as a locus of kinship, status, and communal activity. Invited guests, rites of passage, and communal meals may occur on the central area or veranda. The design and embellishments can reflect clan identity, status, and age-set or ritual roles; decorations may include carved motifs and symbolic patterns.

Terminology and usage can vary by community. In some contexts, walai is used interchangeably with terms for longhouses, whereas in others it designates a specific compound within a longhouse complex. The word also appears in personal or place names in parts of Borneo.
