The houses built by the different tribes and ethnic groups can differ from each other. Houses described as above may be used by the Iban Sea Dayak and Melanau Sea Dayak. Similar houses are built by the Bidayuh, Land Dayak, however with wider verandas and extra buildings for the unmarried adults and visitors. The buildings of the Kayan, Kenyah, Murut, and Kelabit used to have fewer walls between individual "bilik" units. The Punan seem to be the last ethnic group that adopted this type of house building. The Rungus of Sabah in north Borneo build a type of longhouse with rather short stilts, the house raised three to five feet off the ground, and walls sloped outwards.
