### Project Overview

The ARK Trekking Cabin is strategically situated in Latvia's forested landscape, aiming to create a resting and healing point for trekkers by harmonizing with the region's cultural heritage and natural environment. Inspired by traditional Latvian wooden houses, the design employs a diamond-shaped structure that mimics the aesthetics of gemstones while employing materials that reflect the local context. The overarching intent of the project is to promote sustainable practices and environmental integration.

### Design Evolution

The conceptual framework of the cabin revolves around reinterpreting traditional housing forms into a diamond-inspired configuration. This elevated structure minimizes its land impact, reminiscent of tree houses, which enhances its connection with the surrounding environment. The design reflects two main themes: the influence of the natural environment and the reverence for local architectural traditions. By incorporating elements of the local ecosystem, the cabin embodies the area's natural beauty and offers users an immersive experience in nature, while the integration of traditional craftsmanship roots the structure within Latvian culture.

### Materiality and Construction

Construction materials have been selected to emphasize both traditional and modern approaches.
- **Pine Wood** serves as a primary material for structural elements and interior finishes, utilizing local resources effectively.
- **Oriented Strand Board (OSB)** is used for internal cladding, providing necessary insulation and durability.
- **Reinforced Concrete** forms the base of the cabin, ensuring stability for the elevated design.
- **Aluminum** elements are strategically incorporated for weather resistance, while large glazing panels promote natural lighting and a connection to the landscape.

Together, these materials create a cohesive structure that not only meets functional requirements but also respects the environmental context.

`
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.
