NEW. C.T. addresses the need for adaptable living and working spaces for self-employed individuals on Jeju Island. Emerging from the socio-economic pressures brought on by the COVID-19 pandemic, this initiative merges traditional housing concepts with modern needs. The design offers low-cost modular units that support both residential and commercial functions. These spaces encourage a sustainable lifestyle and foster community engagement while allowing safe interactions in market settings.

Material Selection

Hwang To, a traditional Korean soil, serves as a key material in this design. Known for its insulation and humidity control, it aims to maintain a comfortable living environment while reducing energy use. The project also incorporates recycled concrete, which contributes to sustainability by minimizing construction waste and promoting economic efficiency. Additionally, wood is used in various elements, adding warmth and visual appeal that connects the homes with the local natural environment.

Architectural Features

The design features an arch-shaped roof, which effectively reduces wind resistance. This thoughtful form aligns with the climate conditions on Jeju Island, addressing both aesthetic concerns and energy efficiency. A double outer skin in the Ctesiphon structure provides insulation while lessening the impact of wind forces, proving useful for the micro housing concept.

Traditional Elements

Key traditional elements are integrated into the design, such as Daecheong. This feature enhances cooling in summer by utilizing wind convection and ensures warmth during winter months. The C-shaped building layout protects the courtyard from intense winds, contributing to a stable internal climate. Such traditional components meet the cultural and functional needs of the residents.

Thermal Strategy

An important aspect of the thermal design is the use of Ondol panels, a traditional Korean underfloor heating system. It operates by warming the air below the floors, creating even heat distribution throughout the living spaces. The synergy of Hwang To as a finishing material supports heat retention while improving insulation.

The design illustrates a blend of traditional practices with modern living requirements. It prioritizes comfort and functionality while maintaining a strong connection to cultural heritage.

Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
