Hanok

A traditional Korean housing style and architectural cultural heritage characterized by a wooden structure, ondol and maru, and an arrangement in harmony with nature.

Hanok

Overview

Hanok (韓屋) is a term collectively referring to Korea's traditional residential architectural style, and refers to houses built by combining earth, stone, roof tiles, and window paper with a wooden frame. Unlike Western architecture, which is based on masonry (組積式) structures that stack spaces with bricks and stone, hanok is based on a post-and-lintel (架構式) wooden structure that supports loads with columns and beams. Its key features are placing the house without significantly damaging the natural topography and flexibly responding to seasonal changes through the courtyard, eaves, ondol, and maru.

Structure and Characteristics

The skeleton of a hanok is a wooden frame made of columns, beams, and purlins. The roof is made by placing laths on top of rafters and then stacking roof tiles, and the eaves extend deeply to block sunlight in summer and let low winter sunlight deep into the interior. The walls have earthen walls (simbyeok) with doors and windows covered in changhoji (window paper), providing ventilation and humidity control. This structure has some flexibility and resistance against earthquakes and wind loads, and because it is relatively easy to dismantle and reassemble, it is closer to a cyclical architecture that is used for a long time through repeated repairs.

Spatial Composition

Hanok is largely divided into the anchae (inner quarters), sarangchae (men's quarters), haengnangchae (servants' quarters), and byeolchae (detached quarters), and the areas of status, gender, guest reception, and housework were spatially separated. The interior consists of the anbang (main room), geonneonbang (opposite room), daecheong (wooden-floored hall), kitchen, maru (wooden floor), and toenmaru (veranda), and the boundary between inside and outside is gently connected through the maru and courtyard. The courtyard is not simply empty space but a mediating space that draws in light and wind, water and vegetation, and the hierarchy of the walls, gate, sarangmadang, and anmadang creates the order of the entire house.

Ondol and Maru

The elements representing the residential performance of a hanok are ondol and maru. Ondol is a radiant heating method that heats gudeuljang (heated stones) by lighting a fire in the kitchen's agungi (firebox) and transferring that heat to the room floor, and it developed into Korea's unique heating culture. Conversely, maru is responsible for ventilation and cooling in summer, and the daecheong maru was a symbolic space where family rituals and gatherings were held. It contains the wisdom of separating heating and cooling spaces, such as 'the upper room is ondol, the lower room is maru,' and shifting the center of living according to the season.

Materials and Construction

Pine, oak, and other woods were used; earth was used for walls and gudeul; and stone was used for the foundation platform and column base stones. Roof tiles were placed on roofs, and commoner houses were sometimes built as choga (thatched houses) with reeds or straw. Changhoji was a functional material that softly diffuses light and controls humidity. The technique of joining all members with interlocking joints without nails has been transmitted as the core skill of hanok carpenters.

Regional Differences

The form of hanok varied according to climate and local conditions. Northern regions had gentle roof slopes, thick walls, and small windows to block the cold, while southern regions had broad maru and windows and deep eaves for ventilation. Jeju developed low roofs, stone walls, and olle structures to withstand strong winds and rain. Thus, hanok is not a single fixed form but a totality of various lineages adapted to regional environments.

Recent Trends

In 2024–2025, hanok is being reexamined as a 'living cultural heritage' and a sustainable architectural model. The government and local governments are expanding support for hanok preservation and new construction, the creation of hanok villages, and subsidy programs for repairing aging hanok, and places such as Bukchon, Seochon, and Jeonju Hanok Village are actively discussing identity as actual residential spaces beyond tourism resources. In particular, as the carbon storage effect of traditional wooden architecture and natural ventilation and radiant heating/cooling performance draw attention, experiments with 'New Hanok' that incorporate ondol, maru, and courtyard concepts into modern housing and the introduction of hanok style in public architecture are increasing. At the same time, eco-friendly insulation to supplement the insulation and airtightness performance of traditional windows and earthen walls, verification of the structural safety of wooden joints, and training of hanok maintenance personnel have emerged as major tasks. Archiving projects using digital technology to 3D scan hanok members and accumulate BIM data and to record and preserve traditional carpenters' techniques are also underway, and with the spread of K-culture, demand for building or experiencing hanok overseas is also increasing.
