02
Incorporates high-performance insulation materials tailored for local climate conditions.
03
Features a bent A-frame design that maximizes interior volume and natural light.

### Overview
GreenHaus is located in a landscape characterized by extensive greenery and emphasizes sustainable architecture through innovative design and material use. The project aims to create a harmonious connection between the built environment and its natural surroundings. Central to its conceptual framework are passive solar strategies, renewable resource utilization, and a focus on occupant comfort.

### Spatial Dynamics
The architectural layout prioritizes functional organization and spatial flow, effectively merging internal and external areas. Living zones are distinctly delineated yet interconnected, allowing for ample natural light and expansive views. An open-plan design integrates the kitchen, living, and dining spaces to foster social interaction, while transitional zones, such as patios and gardens, serve as buffers between the structure and the surrounding environment. The steeply pitched roof not only facilitates water drainage but also enhances solar energy capture, contributing to the overall energy efficiency of the structure.

### Material Selection
A deliberate choice of materials enhances both the energy performance and aesthetic quality of GreenHaus. High-performance insulation materials are utilized to optimize thermal efficiency, while extensive glass surfaces facilitate natural light and outdoor views. Wood features prominently in structural elements and finishes, contributing warmth to the interiors. The use of recycled concrete in flooring and walls supports durability while minimizing environmental impact. Weathered metals are incorporated into the roofing, providing an enduring visual identity that complements the natural setting. Green roof systems further support insulation and promote biodiversity, reinforcing the project's commitment to ecological sustainability.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
