Recent years have seen a boom in renovation and construction of traditional architecture in Korea. Relatively unknown abroad, the traditional Korean house — called hanok — has become widely popular within the country, and the government is now actively trying to promote its century-old building culture, as seen in central Seoul’s trendy Bukchon neighborhood. In the midst of the hanok boom, my colleagues and I at the architecture firm Urban Detail – Seoul have remodeled a hanok in Seoul’s Myeongnyun-dong area as a joint office for the hanok construction cooperative Chamooree and our own firm. In doing so we hope to contribute to a healthy architecture culture in Korea, embracing both modern and traditional elements.
The hanok shares characteristics with its Chinese and Japanese counterparts but has developed very distinct characteristics due to climatic and cultural circumstances. In premodern Korea, every type of building, regardless of its purpose — residential, official, or religious — was built with basically the same techniques and materials. The materials included stone in the foundation, a wooden frame with walls made of clay and tiles or straw for the roof.
A traditional hanok consists of a series of bang: rooms papered on all sides — even the floor — and heated through the floor using a system called ondol. Other places worthy of note are the daechong — the main hall with a wooden floor and visible beams above — and the bueok — the kitchen whose fireplace feeds the heating system for the whole house. Also important in the spatial conception of the hanok is the madang — the courtyard — used as a a semi-private space for both housework and social interaction.
Most of Seoul’s surviving hanok, besides the palaces and temples, date back to the 1950s and early 60s if not to the Japanese colonial period. They are therefore not architectural examples of the Joseon Dynasty nor truly traditional architecture. Nonetheless, the construction method of the hanok basically remained unchanged during the transition to the Republic of Korea; modifications were made mainly to the heating system and interior materials.
The Chamooree & Urban Detail – Seoul office in Myeongnyun-dong is a typical urban Hanok, probably dating back to the 1930s, the height of the Japanese colonial period. When the building came to our attention, it had already undergone several renovations, which left little of the original interior, but the main structure was original and in a relatively good shape. Our preliminary survey determined that the renovation effort should try to preserve the original main structure while reshaping the interior space according to the needs of a shared office.
The main hall, or daecheong, kept its function but was extended by one intercolumn unit. Guests are welcomed here after entering the building through the main gate into the courtyard.
To the left of the daecheong is the meeting room. Here you can see how the original building was enlarged in the past in order to provide more space. We found an iron H-beam that was installed to replace two columns and decided to integrate it into the interior in order to make such past changes visible. The history of the building can still be read through such elements.
The original anbang — the main bedchamber — was transformed into a work space with an L-shaped desk and work stations for 3 people. The room is open towards the kitchen, which remains in its original location. A sliding door between the meeting room and the daecheong, and the traditional Korean deulmun — doors that can be lifted up and hung from the ceiling — between the daecheong and the work space allow the whole interior to be opened up if need be.
The bathroom remains in its original location, separated from the main interior space by the entryway into the courtyard. While it might be inappropriate to separate the bathroom from the main space at a private dwelling, this struck us as an acceptable solution in an office space. The bathroom and the kitchen are clearly modern in design but fit well with the traditional elements of the house.
A very important aspect of renovating the space was the integration of traditional design and craftsmanship on the one hand and modern elements and materials on the other hand. For example, windows are modified traditional windows with insulation glass and modern sealing but handcrafted by a traditional carpenter specialising in windows. Traditional Korean wallpaper is used in the meeting room and the work space, but for the flooring we chose cork parquet because the traditional Korean flooring made of waxed paper did not seem resilient enough for office use. The walls outside and in the daecheong are finished with lime plaster.
It turned out that a modern-traditional hanok is an excellent space for smaller creative firms like ours. Our interaction is vigorous, and during summer time the courtyard offers many opportunities to organize meetings and events, with outside and inside seamlessly coming together thanks to the transparent facade of the hanok made up of sliding windows. The use of floor heating and natural climate-regulating materials means that the climate within the office is noticeably more pleasant than inside most modern offices.
This project did not have the intention of preserving a historical building with a high proportion of original materials. Such a situation would require a different approach to renovation. But for many of the remaining hanok in Seoul and around the country that retain their original structures but have lost the original interiors, our project could be an example of how to maintain their authentic character and still turn them into attractive and promising spaces.
