Traditional Interior Design
Sophisticated Harmony in Traditional Korean Interior Design
The floor decides almost everything in a traditional Korean room. Heat rises from the ondol, so furniture stays low, the space stays open, and a single room works as living room, dining room and study depending on the hour. Timber, clay and hanji paper cover the rest.
The style settled into its final form in the Joseon-era hanok, built around an open courtyard (madang) and a cool wooden-floor hall (maru).
You rarely see it directly these days. Apartments make up 65.8% of Korean housing (Ministry of Data and Statistics, 2025 census), and the floor heating in those apartments descends from ondol.
What defines traditional Korean interior design?
The hanok is where the tradition landed. The name itself exists to separate the Korean house from the western-style yangok (Asian Art Newspaper).
Oh Hye-kyung’s 1997 study of Joseon upper-class houses (Kyung Hee University) boiled the interiors down to four design concepts. Contemplative, meaning few furnishings and a lot of unoccupied floor. Modest, where the room fits its surroundings instead of dominating them. Raw, so the interior becomes part of nature and not a defense against it. And not decorative, with no crowded ornament, which lets the room speak slowly.
The plainness is deliberate. Hanok interiors are simpler than their exteriors, and the form follows neo-Confucian thought, the ruling ideology of the Joseon dynasty (KOREA webzine, 2025).
Most “Korean style” decor copies a palette and a few objects. The tradition works the other way round. Floor heat sets how people sit, and how they sit sets what the room holds.
Ondol heats by conduction, so daily activity stays near the floor, according to An and Kim in the International Journal of Ondol. Take away the heated floor and the rest of the system stops making sense.
Room layout of a hanok interior
A hanok isn’t one house divided into rooms. It’s a cluster of separate structures around a courtyard, and the main ones are the anchae, the sarangchae and the haengnangchae. They sit in a line or in an L, U or square plan, and the room count followed a family’s size and wealth (KOREA webzine, 2025).
Climate changed the plan. Material from the Architecture and Urban Research Institute (AURI), reported by ArchDaily, ties the northern double-row plan to heat retention and the southern single-row plan to air circulation.
| Region | Plan | Climate response |
|---|---|---|
| North | Double-row, low ceiling | Holds warmth against winter cold |
| Central | L-shaped | Blend of northern and southern plans |
| South | Single-row | Moves air through the rooms |
Room roles in the sarangchae and anchae
The anchae holds the inner quarters and works as the center of the household, set behind a low wall. The master of the house kept to the sarangchae, which served as his study, resting room and place to receive guests. Servants lived in the haengnangchae, which sat lower on sloped sites.
Jo Gil-bang’s House in Dalseong-gun, Daegu shows the pattern in miniature. Its anchae, built around 1784, puts the maru at the core, with the guest room on one side and the main room and kitchen on the other (Inside Inside archive).
Maru and madang as seasonal space
Fire and a wooden floor don’t mix, so hanok pair heated rooms with a wooden-floor maru.
The ondol rooms carry the winter. The maru (called the daecheong in its large hall form) stays cool and shades the interior from summer sun, so a household moves between the two by season.
One room also does several jobs. An ondol room serves as a living room, becomes a dining room when a low table comes in, and turns into a study once the food is cleared (Korea JoongAng Daily, 2021).
The madang courtyard sits at the center of all of it, and the rooms open onto it.
How does ondol heat a traditional Korean room?
Heat comes from below. A fire sends hot smoke through channels under a stone floor, and the stone stores that heat and gives it back slowly.
The path from fire to floor runs like this.
- A fire burns in the agungi (firebox), often at the kitchen hearth.
- Hot air and smoke run through the gorae, the flue channels under the room.
- Flat stone slabs (gudeuljang) sealed with clay mud absorb the heat.
- A clay layer and an oiled-paper finish spread the warmth across the floor surface.
- The smoke leaves through a chimney at the far end.
The sequence follows Korea JoongAng Daily’s 2021 Visual History of Korea feature on ondol. The slabs release their stored heat gradually, so the floor stays warm long after the fire dies down.
The warmest spot, nearest the firebox, went to elders and honored guests. It even had its own name, araetmok.
Because the floor is the heat source, people sat and slept on it. That’s the whole logic behind low furniture and floor bedding.
The temperature profile is also reversed from air-based heating, with a warmer floor and a cooler ceiling, which matches the “warm feet, cool head” condition Koreans prefer (An and Kim, International Journal of Ondol).
The history runs long. L-shaped ondol warmed part of the room in the Goguryeo period (37 BC to 668), and full-room tong ondol arrived in the Goryeo period (918 to 1392), per the Korea Times (2024). In 1425, King Sejong ordered ondol and a bathhouse for Seonggyungwan students suffering skin disease (Kyunghyang Shinmun, 2018). Ondol culture was designated national intangible cultural heritage in 2018 (Kyunghyang Shinmun, 2018; Lim and Kim, 2023).
Fuel is the catch. A traditional ondol burns large amounts of firewood to deliver that long warmth.
Materials that shape a hanok interior
Timber and stone carry most of the building, clay does the insulating, and hanji covers the flat surfaces inside.
| Material | Where it appears | Job |
|---|---|---|
| Timber | Posts, beams, rafters, floors | Carries the load |
| Stone | Footings, ondol slabs | Bears posts, stores heat |
| Clay | Walls, ondol layer, roof fill | Insulates, absorbs moisture |
| Fired tile | Roof surface | Sheds water |
| Hanji | Doors, windows, walls, ceilings, floor | Diffuses light, passes air |
Korean red pine is the usual structural timber, and the frame is joined without nails (Ahn, International Journal of Engineering Trends and Technology, 2021). Posts rest on stone footings.
The roof is built in layers. Wood panels go inside, fired tiles outside, and a thick bed of soil between them gives the thermal effect, according to AURI material cited by ArchDaily.
Hanji is made from the inner bark of the paper mulberry. It covers walls, ceilings and doors, and a bean-oil finish makes it water resistant.
Humidity control is the documented benefit. A 2006 study in Palpu Chongi Gisul (Journal of Korea TAPPI) found that hanji wallpaper regulates indoor humidity, and that adding rice-husk ceramics improves it.
In this tradition the finish does the decorating. Timber grain, the grit of clay and the fibers of hanji supply the texture that other styles buy as ornament.
As of October 2026, hanji’s UNESCO bid is pending. Korea filed the nomination on March 31, 2024, and the Intergovernmental Committee decides at its 21st session in December 2026 (Korea JoongAng Daily, 2024).
How do paper doors and lattice windows control light and airflow?
Changhoji is hanji pasted over a wooden lattice, and the word simply means paper for sliding doors and windows (Khartasia, MNHN). It passes daylight and air while blocking the view.
The light comes through soft and diffused, never as a hard beam. Because the paper passes water vapor, a closed room still ventilates. Privacy means silhouettes, not views. And in warm months the doors slide open so the room merges with the maru.
Nameless Architecture’s door project for the Arumjigi Foundation describes the semi-transparent paper door as one that joins inside and outside instead of separating them. That diffusion is a clear case of light handled as a design material, not a fixture.
A jangjimun door slides in a groove cut into the threshold (munjibang) and makes a soft, heavy sound when it moves (Ahn, International Journal of Engineering Trends and Technology, 2021).
Japanese shoji screens share the paper-over-lattice idea. The Korean version uses hanji and opens onto the maru, where deep eaves (cheoma) keep summer sun off the paper.
Glass sliding doors give away a later hanok. Gwangju News traces them to Meiji-era Japanese patterns used in colonial-era hanok, not to the Joseon dynasty.
Why does the style use low furniture and floor living?
A traditional Korean room holds few pieces, and nearly all of them store or carry things instead of seating people.
The bandaji is a front-opening chest for clothes and blankets, made in regional variants across the peninsula. The jang, a wardrobe, was the costlier option, since most modest households bought a bandaji instead. For meals there was the soban, a small tray table light enough to carry around. A byeongpung, the folding screen, divided a room and doubled as a surface for painting.
The pieces split by quarters. Furniture for the women’s quarters (anbang) carried more decoration, while furniture for the men’s quarters (sarangbang) stayed restrained and let the wood grain show (Korean Antique Furniture).
Big chests were absent until the early 20th century, and the design of most stayed understated. That scarcity is one reason the rooms look empty.
Notice what’s missing from the list. Traditional Korean homes used no chairs, and a raised bed was equally absent.
Palette and decor in a traditional Korean room
The walls and floor stay muted and close to natural, and the saturated color lives in paintings and objects.
The base tones come straight from the materials. Clay, grained timber and pale hanji give a hanok an earthy color palette without a drop of paint.
Obangsaek, the five direction colors, pairs each color with a direction and an element, as the Metropolitan Museum of Art’s catalog entry for a Chung Haecho work lays out.
| Color | Direction | Element |
|---|---|---|
| Blue | East | Wood |
| Red | South | Fire |
| Yellow | Center | Earth |
| White | West | Metal |
| Black | North | Water |
In a hanok room that palette reaches the eye through painted objects, because the walls stay in hanji and timber tones.
Chaekgado, paintings of a scholar’s books and curios, are the biggest color field in the room. The genre emerged in the 18th century, when intellectuals collected antiquities and stationery, and the pictures carry auspicious symbols such as many-seeded fruit for a wish for many children (British Museum).
The same museum notes that bookcase versions borrowed linear perspective and shading from Western painting. The subject also crossed from court painting into folk painting, so one motif hung in palaces and in ordinary homes.
How siting rules decide where rooms and openings go
Siting fixes the house before any room is planned. The hill goes behind it, water in front, and the view gets framed from inside.
Baesanimsu puts a mountain at the back and a river at the front. Nani Park’s Inside the Korean House ties the use of wind and sunlight in hanok to this principle.
Pungsu-jiri, literally the wind-water-earth principles, is Korea’s version of feng shui. Culture Trip points out that it reads mountains and community-scale energy, not furniture placement inside a room.
Chagyeong means “borrowed scenery.” Korean Air’s Morning Calm (July/August 2025) describes it as inviting the existing landscape inward instead of reshaping it, the opposite of jogyeong, “creating scenery.”
The maru, the doors and the lattice windows are the framing devices that make the borrowed view work.
Sources disagree on regional plans. Wikipedia’s hanok entry describes northern hanok as square plans around a courtyard and southern ones as open L-shapes, while AURI material cited by ArchDaily describes double-row northern and single-row southern layouts.
Both name climate as the cause. A surviving southern house, the Jinyang Ha clan house in Changnyeong, has a straight single-story anchae with four front rooms and one side room, which supports the AURI reading (Inside Inside archive).
How does a traditional Korean interior differ from a modern Korean home?
The modern Korean home kept the heated floor and swapped out everything that produced it. Pipes carry the heat, concrete replaces the stone slab, and gas or electricity replaces firewood.
The shift is now the norm. Apartments made up 65.8% of Korea’s housing stock in the 2025 Population and Housing Census (Ministry of Data and Statistics), and nearly all of them use an ondol-derived heating system (Korean Cultural Centre UK).
Traditional and modern compared
| Element | Traditional hanok | Modern apartment |
|---|---|---|
| Fuel | Firewood, later coal briquettes | Gas or electricity |
| Heat path | Firebox and flues under the floor | Hot-water pipes under the floor |
| Floor build | Stone slabs, clay, oiled hanji | Concrete with embedded pipes |
Wikipedia’s ondol entry dates the switch from firewood to coal briquettes to the 1960s, with the stone slab structure kept. The word followed the change, and ondol now covers any underfloor heating in Korean housing (Korea Times, 2024).
How to bring the style into a modern room
- List what the room does from morning to night, then clear everything that serves none of those jobs.
- Bring storage low: one chest, one movable tray table, one folding screen.
- Finish the walls in hanji paper in pale, natural tones.
- Filter window light through a paper screen instead of heavy curtains.
- Add one painted piece, a chaekgado print or a folk painting, as the only saturated color.
- Stop. The empty floor is the finished look.
Start with space planning for a room that changes jobs, because the style works from the layout and not from the objects. A study of 30 Korean restaurants reached the same conclusion: tradition has to cover space, elements and decoration together (KoreaScience).
Measure each wall before ordering paper, and let a wallpaper quantity calculator convert the dimensions into rolls.
Two documented projects show the approach at larger scale. Designer Teo Yang shaped the Lotte World Tower’s top-floor windows after the curves of Korean ceramics and traditional writing brushes (Korea JoongAng Daily), and the Hanok Heritage House lines guest rooms with hanji light walls and hanji flooring (Architizer).
Where to see preserved interiors
- Bukchon Hanok Village in Seoul, a lived-in district with a hanok museum in the Baek In-je House
- Namsangol Hanok Village in Seoul, a recreated village where you can get a feel for the traditional lifestyle
- Jeonju Hanok Village in North Jeolla, one of the largest hanok districts in Korea
- Korea Furniture Museum in Seoul, an aristocratic hanok with period furniture, founded in 1993
Treat Bukchon as an urban hanok district, not a Joseon one. Nearly all hanok there were built after 1930, yet Seoul’s design guidelines for subsidized work rest on Joseon-period concepts (Korea Times, 2011).
Rules attach to designation. Seoul has registered hanok since revising its construction ordinance in 2001, and registered owners can get repair subsidies and a property-tax discount (Seoul Solution).
In Seochon, hanok designated areas allow only hanok, while recommended areas let other buildings stand up to 2 to 3 floors. AURI’s 2015 survey counted 616 hanok there, 50 to 60 fewer than in 2010 (Korea JoongAng Daily).
When does a traditional Korean interior stop working?
It stops working when upkeep stops or when only the surface gets copied. The documented failures run from timber movement and paper aging to substandard hanji, vague repair guidance and decor without the room logic behind it.
Timber moves. A 2015 monitoring study of two test houses found higher moisture content in the raw-wood traditional hanok, and rafter deflection about twice that of a modernized glued-timber hanok.
Paper ages, and heat makes it worse. In a study of commercial hanji, dry-heat aging cut optical and mechanical properties more than wet-heat aging, which matters most for paper laid over a heat source.
Grade matters too. Traditional hanji used paper mulberry bast fiber only, while hanji sold today is mostly mixed with waste paper, a practice a 1998 Chungbuk National University study linked to quality problems.
Even the repair rulebook has gaps. A 2023 proposal by Lim and Kim found terminology and structure errors in Korea’s standard specification for heritage ondol repair, errors that confuse repairers on site.
Then there’s plain surface imitation. Traditional elements appeared in about 50% of hotel Korean restaurants and 25% of department-store ones in a KoreaScience study, which concluded that the traditional space structure has to be applied too.
Outside a heritage repair, rebuilding a stone-slab ondol rarely makes sense. Hydronic floor heating already delivers the warm floor, and paper, low storage and one painted piece deliver the look.
Floor living also assumes the household is comfortable getting down to the floor and up again. If that’s not true for you, keep one chair and accept the compromise.
Traditional Korean Interior Design FAQ
Can you stay overnight in a hanok?
Yes. The Korea Tourism Organisation runs a Hanok Stay Programme that helps visitors find hanok for rent or homestay.
Bukchon in Seoul has hanok stays with ondol-heated floors and hanji doors.
How much does a hanok renovation cost?
No fixed figure applies, because the scope of work differs from house to house.
A KoreaScience study of hanok carbon stock lists high construction costs among the main factors slowing the hanok industry, alongside limited government support.
Is ondol the same as the Chinese kang?
Not quite, and the origin is disputed. Chinese commentators trace ondol to the kang, a raised clay heating structure from northeast China, while Korean sources point to Goguryeo-era L-shaped ondol.
A 2024 Korea Times piece adds that ondol is wrongly linked to the Roman hypocaust.
How do Korean traditional interiors differ from classic Chinese ones?
Korean rooms use no chairs or raised beds, where Chinese interiors favored high-backed chairs and lacquered cabinets (Pooltable Portfolio).
Korean rooms also carry fewer decorative objects, such as the pillows that pile up in Chinese-style sofa sets (Artsper).
Why does a hanok connect the kitchen to the heated rooms?
One fire does two jobs. The kitchen firebox cooks the meal, and its hot smoke then runs under the floor of the next room (Korea JoongAng Daily, 2021).
Northern-region hanok often add a jeongjugan, a space between the kitchen and the other rooms that the same ondol warms.
Keeping a Traditional Korean Interior in Good Condition
Upkeep follows one rule, inspect from the structure outward. Frame first, heated floor second, paper last. That means checking the timber frame and its moisture, then the paper laid over the heated floor, and the hanji grade at every re-papering.
The order follows dependency. A sagging frame shifts every door and wall surface fastened to it, so re-papering before checking the frame wastes the repair.
The trade-off is vigilance in place of a schedule. No source reviewed gives a re-papering interval, so a household that keeps original materials accepts regular inspection and visible wear as the price.
