## Architectural Design Overview

Located in Asheville, North Carolina, this residence integrates contemporary architectural principles with the surrounding natural landscape. The design aims to establish a harmonious relationship between indoor and outdoor environments while prioritizing sustainability and resource efficiency. Drawing on the area's topography and climate, the project embodies a commitment to enhancing the quality of life for its inhabitants through thoughtful spatial configurations and material choices.

### Spatial Configuration

The layout features an open-plan design that facilitates fluid transitions between indoor and outdoor areas. The living space, characterized by expansive floor-to-ceiling windows, maximizes natural light and offers unobstructed views of the surrounding mountains. The kitchen is strategically situated within the living area to enhance social interaction and is equipped with energy-efficient appliances. Bedrooms are positioned to ensure privacy while still allowing for panoramic vistas. Each bedroom includes an ensuite bathroom, promoting both comfort and functionality.

### Material Selection and Sustainability

Materiality plays a pivotal role in the project, balancing aesthetic appeal with environmental considerations. Locally sourced cedar is utilized for exterior cladding, providing natural weather resistance and blending with the forest backdrop. Low-emissivity glass is employed in windows and sliding doors to optimize energy efficiency, while reinforced concrete forms the backbone of the structure, benefiting from its durability and thermal properties. Natural stone accents in pathways and the foundation integrate the building into its landscape, and recycled metals are used for roofing and structural elements to further emphasize a commitment to sustainability.

The design incorporates a green roof, which contributes to natural insulation and supports biodiversity. Outdoor living areas are furnished with sustainable materials, promoting engagement with the environment. An innovative rainwater harvesting system efficiently collects and reuses rainwater for irrigation, reinforcing the project's ecological focus.

`
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.
