Universal House Sun House is a modular residential prototype developed as part of the Universal House Pattern Village near Seoul, South Korea. Together with the Community Center, Moon House and Metal House, the project explored alternative construction systems, digital fabrication and adaptable housing typologies.
The house is organised as a series of room-sized modules that interlock, stack and shift in plan to create a highly compact yet spatially rich dwelling. By offsetting the modules from one another, the design generates a network of openings, visual connections and oblique sightlines that extend through the entire house, creating a sense of spatial complexity beyond its modest footprint.
The project was conceived around the use of CNC-milled formwork and cast concrete construction. At the same time, the geometry was deliberately developed to allow alternative manufacturing methods, including large-scale 3D printing and hot-wire-cut foam fabrication. This flexibility made the project an early exploration into how architecture could be designed simultaneously for multiple digital production technologies.
The modular system combines the efficiency of prefabrication with the spatial diversity of bespoke architecture. Each component performs as both structure and space, allowing the house to be assembled from a limited number of repeated elements while maintaining variety in plan, section and experience.
Universal House Sun House represents UFO Architecture's early research into computational design, modular construction and digitally manufactured architecture, investigating how advanced fabrication methods can generate new forms of residential living.
