### Overview
The Trekking Cabin, located along the Latvian coast near the Baltic Sea, serves as a retreat for hikers seeking rest and revitalization in a natural setting. Drawing from traditional architectural motifs of Latvia, the design blends cultural elements with modern aesthetics and emphasizes environmental responsibility. The intent is to create a functional space that offers not only shelter but also a sense of familiarity and connection to the surrounding landscape.

### Material and Structural Strategy
The cabin's design incorporates a carefully selected materials palette that underscores aesthetic appeal and functionality. The exterior features wood cladding that enhances thermal performance while integrating the structure into its natural environment. Additional elements include an insulating air gap, water-resistant roofing materials, and sustainably sourced oriented strand board (OSB) cladding to promote structural stability. Large strategically placed windows are designed to maximize natural light and create visual continuity with the outdoors.

Internally, the layout balances communal and private spaces, with sleeping quarters distributed across upper and lower levels, while the ground floor accommodates cooking and socialization areas. Design elements, such as a central living space and pathways that connect the unit to its surroundings, encourage interaction among users. Unique features include an integrated rainwater collection system and designated areas for relaxation, thereby enhancing both sustainability and user experience.

`
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.
