Constructed with rammed earth walls, this design integrates a central nucleus that facilitates efficient air circulation and sunlight capture, creating a sustainable living space with distinct zones for work and rest.
5 key facts about this project
01
Rammed earth walls enhance thermal mass and energy efficiency.
02
The central nucleus design separates social and private areas.
03
Orientation of walls maximizes natural light and passive heating.
04
High-efficiency fireplace improves comfort and air quality.
05
Rainwater collection system supports sustainable resource use.

The design centers around a free plan concept with a central nucleus that plays a crucial role in meeting the functional needs of a home. Located in an environment that values sustainable living, the layout offers two spacious zones that maintain privacy and usability for various activities. This thoughtful organization avoids the need for extra walls, allowing for a more open and inviting atmosphere.

Central Nucleus

The nucleus serves two primary functions. One side is dedicated to a kitchen that also acts as a dining area and workspace. The other side features a high-efficiency fireplace, which caters to the living room and bedroom. This arrangement maximizes the use of space while still allowing for social interaction among residents, making daily life more comfortable.

Air Circulation and Comfort

Attention to air circulation significantly contributes to the design's comfort. The nucleus is intentionally lower than the adjoining ceiling, creating a flow of fresh air throughout the home and improving fireplace performance. This detail shows a clear understanding of thermal dynamics, enhancing energy efficiency and overall livability.

Material Use

Prefabricated components and locally sourced earth form the foundation of this project. The use of rammed earth gives structural strength to areas designated for living and working. Walls made from rammed earth are carefully positioned to catch sunlight, which helps to warm the space naturally while maximizing daylight exposure.

Sustainable Features

The design incorporates a pre-fabricated cover that holds solar panels and includes a rainwater collection system. Such features emphasize a commitment to sustainability and efficient resource management. All walls connect securely to the foundation, which not only ensures stability but also contributes to the overall durability of the building.

The design ultimately reflects a practical approach to living. Every feature is carefully selected to enhance the experience of the residents, creating an environment that supports both functionality and a connection to the surrounding landscape.

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.
