### Project Overview

The "Parasitic Home" project responds to the housing crisis in South Korea, particularly within the densely populated district of Nowon-gu, Seoul. Accelerated urbanization following the Korean War has resulted in significant housing shortages, necessitating innovative architectural solutions. This initiative proposes an adaptive model for urban living by integrating modular housing units that extend pre-existing high-rise buildings. By enhancing individual living environments, this design promotes sustainability and fosters community interaction.

### Spatial Strategy and Modularity

The central concept revolves around the notion of "parasitism," where modular housing units are affixed to existing structures, effectively utilizing vertical space in urban settings while minimizing land consumption. This approach addresses the urgent need for vertical living solutions in areas with high population density and creates flexible accommodation options. Residents can personalize their living spaces, facilitating a range of configurations that cater to diverse lifestyles and requirements.

### Materiality and Sustainable Features

Constructed using a selection of modern materials, the design prioritizes both functionality and sustainability. Key materials include:

- **Polystyrene Roofing:** Offers insulation and protection against weather elements.
- **Waterproofed Polyurethane Insulation Sheets:** Enhance thermal efficiency.
- **Metal Cladding Panels:** Provide durability and low maintenance.
- **Wood Finishes:** Introduce warmth to interior spaces.
- **Glass Windows:** Optimize natural light and encourage outdoor connectivity.
- **Solar Panels:** Facilitate renewable energy generation.
- **Rainwater Harvesting System:** Supports sustainable water management.
- **Precast Concrete Elements:** Form crucial structural components of the existing buildings.

These components collectively support the project's commitment to reducing environmental impact while improving the quality of life for residents. The design emphasizes ample natural light through large windows and skylights, enhancing overall well-being within the living spaces.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
