Top 10 Traditional Houses of Indonesia 2026

Across the interior of Kalimantan, the traditional home of many Dayak communities is not a single-family house but a longhouse, known locally as rumah betang in much of Indonesian Borneo and rumah panjai or lamin in related traditions nearby. Built entirely on stilts, a rumah betang can run to well over a hundred metres in length in its largest historical examples, sheltering dozens of related families under one continuous roof. The internal layout follows a consistent logic wherever it is built: one long side of the building is given over to a shared public gallery, called the ruai, which runs the full length of the house and serves as the community's meeting hall, workspace and social space combined. The other side is divided into a row of private family apartments, or bilik, each housing up to three generations of a single family, with a door opening directly onto the shared gallery. Traditional construction relied on tree trunks for the main structural posts and beams, split bamboo or small logs for flooring, long palm leaves for roofing, and tree bark for wall panels, with Bornean ironwood, prized for its density and rot resistance, used for the load-bearing piles wherever it was available; modern longhouses increasingly mix in brick, cement and zinc roofing while keeping the same communal floor plan. A rumah betang functions as more than housing. It doubles as a house of worship for community religious ceremonies and is governed day to day by an elected or hereditary leader, a tuai, responsible for enforcing the customary rules, or adat, that bind everyone living under its roof. Surviving and actively inhabited longhouses can still be visited in West and Central Kalimantan, including examples such as Rumah Betang Sei Pasah, where visitors are usually welcomed by the resident community rather than given a museum-style tour.

Ruma Bolon, usually shortened to the bolon house in English, is the traditional dwelling of the Batak Toba people around Lake Toba in North Sumatra, most visibly preserved today in villages on Samosir Island. Early accounts describe bolon houses as the residences of ranking figures in Batak society: tradition holds that thirteen successive Batak kings lived in bolon houses over the centuries, and the style was historically tied to chiefly and clan authority rather than to ordinary households. The house is built entirely of wood, raised above the ground, and roofed with rumbia, or sago palm, leaf thatch rather than tile or shingle. Inside, a bolon house has no internal walls dividing it into separate rooms in the way a modern house does; instead, the single continuous interior space is informally divided by function and by the social position of different family members, following customary Batak rules about where people may sit, sleep or receive guests. Exterior gables and structural beams on ceremonial and chiefly houses were traditionally finished with gorga, elaborate carved and painted geometric and figurative motifs that also appear on other Batak Toba cultural objects, from cloth to musical instruments. Very few bolon houses remain standing today outside a handful of preserved clusters, since most Batak families now live in conventional housing, but a number of well-known examples survive as heritage sites on Samosir Island, including restored compounds that combine several bolon-style buildings together with reconstructed rice barns and carved ceremonial gateways. These clusters, reached by the short ferry crossing from Parapat, are usually the first stop for visitors wanting to see traditional Batak Toba architecture in person rather than in a museum display case.

Honai is the traditional round house of the Dani people and other highland communities of Central Papua and Highland Papua provinces, built for a climate that is nothing like the tropical coast most visitors associate with Indonesia: nights in the Baliem Valley highlands, at well over 1,500 metres elevation, regularly turn cold. The building's whole design answers that cold directly. A honai is small, round and low, typically standing five to seven metres tall across two internal levels, with thick chopped-plank walls, a wooden beam frame, and a steeply thatched roof of fruitwood and cogongrass that comes almost to the ground, leaving only a small door and no windows at all. That tight, enclosed shape traps heat efficiently, and a central hearth called a hipere, kept burning through the night, warms both the cooking and sleeping levels above it, doing double duty as stove and heater in a house with no glazing to lose warmth through. Traditional Dani settlement is organised by sex as much as by family: the honai proper houses men, a separate round house called the ebai shelters women and young children, and a third structure, the wamai, keeps domestic animals such as pigs. All three take their names from the Dani word ai, meaning house, with a descriptive prefix attached. Construction traditionally used rattan rope or split tree roots for binding rather than nails, though contemporary honai increasingly incorporate nails, small windows and zinc roofing sheets, trading some of the original insulation for lower maintenance. Honai remain in everyday use, not just as heritage displays, in villages around Wamena in the Baliem Valley, and a number of them are open to visitors travelling with local guides as part of wider Baliem Valley cultural treks.

Omo sebua, sometimes written omo hada, is the chief's house of the Nias people, an island community off the western coast of Sumatra whose traditional architecture is built to survive one of the most earthquake-prone stretches of coastline on Earth. The best-known surviving example stands in Bawomataluo, a hilltop village in South Nias reached by a long stone staircase, where the chief's omo sebua measures 19 by 30 metres and is described by researchers as the oldest and largest such house still standing on the island. The house's oversized wooden beams, some of the largest used in any Indonesian vernacular building, are assembled without a single nail, an approach shared with several other Indonesian traditional houses but taken furthest in Nias construction, where the flexible, pegged timber frame is credited with helping the buildings flex rather than crack during earthquakes. Bawomataluo itself sits on a flattened hilltop, its central plaza paved with megalithic stone tables and monuments once used for ceremonies and, historically, for displaying the status of local chiefs. That same plaza is the setting for fahombo, the Nias stone-jumping tradition, in which young men leap over a stone wall about 1.8 metres high. Historically the wall's top edge was fitted with sharpened sticks as training for war; in the ceremonial jumping performed for visitors and festivals today, the sharpened edge has been removed. Bawomataluo was placed on Indonesia's national Tentative List for UNESCO World Heritage nomination in 2009, recognised for combining traditional architecture, megalithic culture and the stone-jumping tradition in a single living village rather than a restored museum site.

Rumoh Aceh, simply Aceh house in the Acehnese language, is the traditional stilt house of the Acehnese people at the northern tip of Sumatra, built entirely of wood without a single nail, in a style adapted to the province's monsoon climate. The house stands on wooden posts resting on flat stones or plinths rather than driven into the ground, with woven bamboo walls, feather-palm plank flooring and a thatched sago-palm roof. Inside, a rumoh Aceh divides into three distinct zones running front to back, each with its own name and social meaning. The front section, seuramoe keue, is the male realm, an open reception area used for receiving guests and public activities. Behind it, raised half a metre higher, sits the rumah inong, the parental house, containing the family's bedrooms along a central corridor and functioning as the private core of the home. At the rear, the seuramoe likoot is the female realm, where cooking and everyday domestic work take place, away from the eyes of visitors in the front section. Traditionally, houses were oriented with their gables facing east and west, an alignment researchers connect to older beliefs about life and death that predate Islam's arrival in Aceh, though some later houses reoriented toward Mecca after Islamisation reshaped the region's religious life. Exterior woodcarving in floral and geometric patterns decorates the triangular gable panels, window surrounds and boards, with perforated gable screens doing double duty as ventilation in the tropical heat. Genuine rumoh Aceh are now rare and, by the account of researchers who study them, on the verge of disappearing entirely, squeezed out by timber scarcity and by younger Acehnese families who see the layout as poorly suited to modern life. The clearest place to see the style preserved is the Aceh Museum in Banda Aceh, itself built around a historic rumoh Aceh structure originally used as the Aceh Pavilion.

Uma mbatangu, peaked house, is the traditional dwelling of the Sumba people on Sumba island in the Lesser Sunda Islands, and its most distinctive feature is a soaring, tower-like thatched roof peak rising high above the living quarters below. That peak is not just decorative: in Sumbanese belief it is where the marapu, ancestral spirits central to traditional Sumbanese religion, are understood to reside, which is why only certain eastern Sumba houses are built with the tall peak at all. Houses without it, built in a lower, flatter style found elsewhere on the island, are known by contrast as uma kamadungu, bald houses. The house's structure mirrors a three-level cosmology that runs from underworld to sky. The raised upper space beneath the roof peak is sacred, used to store ceremonial heirlooms and understood as the residence of the marapu; the middle level, at ground height, is where the family actually lives and works day to day; and the space beneath the raised floor houses livestock, particularly the buffalo and horses central to Sumbanese wealth and ceremonial exchange. This vertical arrangement of sacred, human and animal space is common to Austronesian house-building traditions across the archipelago, but Sumba's version, with its dramatically tall peaked roofs, is among the most visually striking anywhere in Indonesia. Traditional Sumba villages compound the effect further by building these houses in a ring around a central plaza filled with megalithic stone tombs, so that domestic architecture and funerary monuments share the same open space rather than being kept separate. At Wainyapu village, in the island's southwest, new dolmen tombs were still being built and dragged into place by entire communities as recently as 2021, alongside houses that continue to be lived in day to day. Ratenggaro and Praijing, both also in southwest Sumba, are among the most visited surviving clusters of peaked-roof houses, their silhouettes rising above the surrounding grassland.

A baileo is not a house at all in the way the other buildings on this list are; it is the communal ceremonial hall found at the centre of traditional villages across Maluku and North Maluku, and it is usually the single largest, most architecturally distinctive structure in any village that has one. The name is thought to derive either from the Malay bale or balai, meaning a village meeting place, or from the Portuguese baileu, reflecting centuries of Portuguese trading contact in the Maluku islands before Dutch colonial rule. Structurally, a baileo is deliberately open: built on stilts with an open-sided design rather than enclosed walls, using planked timber, stone, brick or cement for its base and posts, and roofed in wood shingle, thatch or, in more recent construction, corrugated zinc. That openness suits its function. A baileo serves as the meeting hall where village elders and the wider community gather to discuss administrative matters and settle disputes under customary law, and it is also where sacred heirlooms and ceremonial objects belonging to the village are traditionally stored and displayed during festivals. In some Maluku villages, the baileo's ceremonial role overlaps directly with organised religion: certain baileo function as, or stand immediately beside, a village mosque or church, reflecting how thoroughly the building's communal and spiritual roles have blended with Islam and Christianity since their arrival in the islands, without displacing older adat customs entirely. Surviving baileo can still be seen in a number of villages across Ambon Island and the surrounding Lease Islands, including Asilulu, Haria and Seith, each rebuilt or restored more than once over the centuries but maintaining the same open, elevated hall form and central role in village life.
