When designing the House of Three Trees, Seoul-based architecture practice Jae Kim Architects & Researchers (JK-AR) started with a question: What would Korean architecture look like if timber remained the dominant construction material from ancient times until today? To answer this alternate-reality proposition, the architects conceived a project representative of “the rebirth of East Asian timber architecture of the 21st century” that blends digital design and fabrication with traditional Korean architecture. Built with sculptural, tree-like structures that employ the iconic wooden bracket systems of ancient times, the experimental home also relates to the local vernacular with low-cost materials commonly used in rural Korean buildings.
During the late Joseon Dynasty of Korea in the 17th and 19th centuries, timber resources were mostly exhausted until globalization led to the import of cheaper wooden materials from around the world. Due to the popularization of reinforced concrete structures and the high cost of timber construction, development of timber architecture slowed.
Using algorithmic tools, JK-AR envisions how timber architecture could have evolved had timber resources continued to be readily available with The House of Three Trees. The experimental home features tree-like supporting structures solely composed of wooden joinery — using more than 4,000 timber elements — constructed with traditional techniques and zero additive fasteners.
“The house criticizes today’s application of traditional buildings that is superficial, merely imitating traditional expressions in architecture, or too abstract,” the architects explained. “Rather, the house redefines the virtue of East Asian timber buildings in its tectonic aspect which is a combination of structure and ornamentation. Moreover, the house serves as an example of how contemporary technology, such as design computation and digital fabrication, can reinterpret traditional architecture. Technology can give East Asian timber construction the potential to evolve in a new direction.”
The home takes on a hexagonal shape, influenced by the irregular building plot, with an interior defined by three tree-like columns that support the roof. Covered in asphalt shingles, the butterfly roof is raised to provide a glimpse of the trees inside. Polycarbonate corrugated panels wrap around the home in a nod to rural Korean construction; these panels also create a double-skin around the plywood facade to improve the building’s insulation performance and water resistance.
