### Overview

"In Optimum" is situated in a remote landscape characterized by expansive snowfields and mountainous terrain. The design aims to harmonize with its natural context while addressing both functional and aesthetic requirements. The structure is conceived to foster a contemplative relationship between human habitation and the surrounding environment, reflecting principles of sustainability, locality, and simple elegance.

### Materiality and Sustainability

The predominant use of dark stone as a primary material contributes to the building's identity and functionality. This material not only provides thermal mass essential for colder climates but also establishes a tactile connection to the local geology. Reinforcing this choice, concrete is utilized in structural elements for durability, while glass is strategically incorporated to enhance natural lighting and facilitate a visual connection with the outdoors. Such material choices reflect a commitment to sustainability and a focus on minimizing the ecological footprint through the use of local resources.

### Spatial Configuration and User Experience

The design features a series of large vaulted arches, instilling a sense of volume and inviting natural light, which enhances the internal atmosphere. The floor plan incorporates dedicated areas for communal activities, equipment maintenance, and entry transitions, ensuring a functional and adaptable environment. The interior's illuminated elements and spaciousness create an inviting ambiance, encouraging exploration and reflection. This thoughtful spatial arrangement is intended to support social interactions and facilitate a seamless user experience amidst the challenges of the natural landscape.

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.
