Subscribers only
With a Vertical Platform Lift enhancing accessibility and Aerated Concrete providing durability, the design prioritizes sustainable living through integrated solar cladding and self-sufficient gardening spaces for a couple adapting to their new home.
5 key facts about this project
01
Vertical Platform Lift enables easy access to all levels of the home.
02
Integrated rainwater collection system supports sustainable water management.
03
Planter boxes promote self-sufficiency in food production.
04
Solar PV cladding enhances energy efficiency and renewable energy use.
05
Aerated Concrete panels provide durability and effective thermal insulation.

The design is located in a rural area between Phnom Penh, the capital of Cambodia, and Sihanoukville, a key industrial city. It is intended for a newly-wedded couple who are handicapped, having lost their legs due to landmine incidents. The concept focuses on creating a home that meets their specific needs while emphasizing functionality, accessibility, and sustainability.

Modularity and Adaptability
The approach is based on modular design, drawing inspiration from container architecture. This allows for both horizontal and vertical growth, making it possible for the living space to expand as the family grows. Each module is designed to provide essential living areas while remaining flexible enough for future adjustments, reflecting the occupants' changing needs.

Accessibility Features
Access is a critical aspect of the design, with elements in place to accommodate the couple's requirements. A Vertical Platform Lift (VPL) is included to enable easy movement between different levels of the home, including access to the roof terrace. This feature helps ensure that all spaces are reachable, allowing the occupants to navigate their home independently.

Sustainable Practices
Incorporating sustainability is vital, especially in the context of Cambodia’s environment. Planter boxes are featured to support the growth of vegetables, herbs, and spices, encouraging self-reliance in food production. A rainwater collection tank is incorporated into the system to help conserve water, addressing local climate challenges. Also, solar PV cladding on the East and West facades enriches energy management, using sunlight to power the home.

Material Selection
Material choices focus on durability and energy efficiency. The project employs Aerated Lightweight Concrete (ALC) panels, which are key to the structure's stability and thermal properties. This material aligns with the goals of creating a sustainable and long-lasting living environment.

Large windows allow natural light to fill the interior, creating a welcoming atmosphere while offering views of the landscape. The design encourages an enhanced connection with the surrounding environment, emphasizing harmony with nature.

`
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.
