Subscribers only
Utilizing local stone and precast concrete beams, the design fosters a strong connection between indoor and outdoor living spaces, culminating in a residence that prioritizes sustainability and functionality.
5 key facts about this project
01
Precast concrete beams provide rapid assembly while maintaining structural integrity.
02
Local stone walls enhance thermal insulation and connect the design to its surroundings.
03
Service cells manage water purification and energy storage effectively within the structure.
04
Landscaped patios improve natural ventilation and create cohesive indoor-outdoor spaces.
05
Large glass facades maximize daylight, contributing to energy efficiency and occupant comfort.

### Project Overview
Located in a region optimized for natural light and ventilation, the residential design prioritizes ecological sustainability and open space integration. The configuration fosters connectivity among various living areas, aiming to create a cohesive environment that balances functionality with aesthetic appeal. The design utilizes large landscaped patios to promote privacy while enhancing the flow of light and air throughout the dwelling.

### Spatial Strategy
The architectural layout is meticulously planned to support modern lifestyles that require flexibility and interaction.
- **Ground Floor:** Features a welcoming entrance leading into an expansive living area that adjoins the dining space. The open kitchen connects directly with shared areas, facilitating communal cooking and dining experiences. The inclusion of multiple patios—such as those designated for service, planting, and recreation—serves as vital links to the outdoors.
- **First Floor:** Comprises private sleeping quarters, including a master suite and additional bedrooms that prioritize comfort. Shared zones such as an open office and playroom encourage productivity and leisure, promoting family connectivity.

### Materiality and Sustainability
The material selection reflects a commitment to sustainability and local sourcing, emphasizing environmentally responsible design practices.
- **Primary Materials:** Precast ecological concrete beams form the structural foundation, allowing for efficient assembly and minimal waste generation. Local stone walls enhance insulation properties while contributing to the visual aesthetic. Solar panels are integrated into the structure, reducing reliance on conventional energy sources. Sandstone is employed for its durability and aesthetic warmth, while glass facades maximize daylight and create a visual link between interior and exterior spaces.

The design incorporates innovative features, such as a patio system that actively supports natural ventilation and integrates cultivation areas, and service cells that manage water systems efficiently. A cross-ventilation strategy is implemented to optimize thermal comfort and minimize energy consumption throughout the year.

`
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.
