### Overview

Located along the Baltic Sea coastline, the Amber Road Trekking Cabins are designed to provide a retreat for outdoor enthusiasts. This project integrates traditional architectural aesthetics with modern design principles while prioritizing sustainability. The design establishes a strong relationship between the built environment and its natural surroundings, facilitating relaxation and rejuvenation for its users.

### Material Selection and Sustainability

The architectural approach emphasizes the use of sustainable materials that enhance both aesthetic and functional performance. The roof is made from marine-grade plywood finished with linseed oil and natural pigments, reflecting the region's architectural heritage, while incorporating compressed resin-impregnated straw insulation for thermal efficiency. Structural frames utilize European pine sourced from plantation-grown forests, connected through European oak dowels, demonstrating a commitment to minimal environmental impact.

Wall assemblies feature radial cut sustainable spruce boards layered with insulation and finished with birch plywood, contributing to energy efficiency and visual warmth. The flooring integrates larch plywood with similar insulating qualities, maintaining a natural aesthetic. Innovative window frames constructed from solid balsa wood are treated with natural resins and include polycarbonate sheeting for improved ventilation. Each chosen material serves to create a cohesive design philosophy focused on aesthetics and sustainability.

### Spatial Organization and User Interaction

Attention to spatial organization facilitates a functional and inviting environment. The interior layout promotes interaction, featuring open areas that encourage social engagement alongside spaces designed for solitude. Large windows frame views of the Baltic Sea, allowing for ample natural light and fostering a strong connection to the surrounding landscape. This design strategy supports both communal and individual experiences, enhancing the sense of mindfulness and tranquility.

The use of lightweight prefabricated construction methods allows for efficient assembly and transportation while minimizing the construction's environmental footprint. The cabins are conceived not only as shelters but also as self-sufficient units, reflecting a resilient approach to architecture in a remote setting.

`
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.
