Utilizing a hexagonal layout and galvanized steel construction, the home harmonizes with the rugged terrain of Serra da Estrela, offering a compact and efficient living space for a small family.
5 key facts about this project
01
Utilizes a hexagonal design to optimize space efficiency.
02
Constructed primarily with galvanized steel for durability and low maintenance.
03
Incorporates geothermal systems for effective heating and cooling.
04
Features a rainwater harvesting system for sustainable water use.
05
Integrates seamlessly with the mountainous landscape of Serra da Estrela.

The modular home is located in Serra da Estrela, Portugal, a region known for its mountains and varied climate. The design focuses on creating a personal space that fits comfortably within its natural surroundings. The main idea uses a hexagonal shape to enhance the use of space, allowing light and air to flow into the home while connecting the interior to the outside landscape.

Spatial Organization

The layout includes a master bedroom and a child’s bedroom, along with shared spaces like a hall, dining area, kitchen, and living room. This organization allows for family interactions while maintaining private areas for rest and reflection. Each section is purposefully arranged to facilitate daily activities while ensuring easy movement throughout the home.

Material Selection

Galvanized steel serves as the primary material for the structure. This choice is driven by its strength and resistance to corrosion, making it suitable for the region's changing weather. Galvanized steel also means reduced maintenance over time, contributing to the home’s durability.

Sustainability Features

The design incorporates various features that promote sustainability. Geothermal systems harness the earth's natural warmth for heating and cooling, improving energy efficiency. A rainwater harvesting system is also included, which collects water for non-drinking purposes. These components reinforce a commitment to environmentally responsible building practices.

The interior finishes use earthy tones that reflect the surrounding landscape. Natural materials create a warm atmosphere, inviting residents to make the space their own. Each room balances personal style with a cohesive design, resulting in a home that is both functional and comfortable.

`
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.
