Utilizing thermal waters for radial heating, the microhome offers a customizable living space designed for energy efficiency and sustainable resource management.
5 key facts about this project
01
Utilizes thermal water for efficient radial heating.
02
Gray water is treated and repurposed for non-potable uses.
03
Incorporates CNC Router technology for precise modular construction.
04
Offers four customizable terrace options to enhance outdoor living.
05
Located in the thermal-rich landscape of Termas de Chillán.

The microhome project is situated in the Ñuble region of Chile, specifically in the town of Termas de Chillán. It focuses on using natural thermal resources to provide a comfortable living environment that emphasizes energy efficiency. The design incorporates thermal waters for heating, addressing modern needs for sustainability while offering a flexible layout that can adapt to individual preferences.

Thermal Resource Utilization

The concept relies on a radial heating system that takes advantage of the thermal waters in the area. This system helps maintain a consistent internal temperature, especially in the colder months, which reduces dependence on external heat sources. By harnessing geothermal energy, the design promotes a practical approach to residential heating along with the health benefits of having warm thermal water accessible.

Water Management System

A significant aspect of the microhome is its effective water management system. Gray water is managed through an underground containment system, enabling treatment and reuse for non-drinking purposes. This choice minimizes waste and shows a commitment to environmental responsibility by making efficient use of available resources.

Modular Design and Customization

CNC Router technology plays a key role in the construction of the microhome, offering precision and speed. This modular design allows for high levels of customization, so future residents can adapt their living spaces to meet their specific needs. The flexible layout provides opportunities for personal expression, making it easy to design a home that fits a variety of lifestyles and preferences.

Terrace Integration

The design features several terrace modules that enhance outdoor living space. Residents can choose from four different terrace options, integrating them with the main structure. This addition not only extends the functional area of the home but also encourages residents to connect with the surrounding landscape, promoting a harmonious relationship with the environment.

The project combines practical design with thoughtful environmental considerations, resulting in a microhome that fits well within its setting while providing comfort and adaptability for its inhabitants.

`
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.
