Hexagonal Cabins With Polycarbonate Roofs Integrating Sustainable Timber Construction Along Latvia's Trekking Routes

Project in-detail

Constructed with hexagonal forms and polycarbonate roofs, these cabins utilize sustainable timber to provide essential shelter along Latvia's extensive trekking routes.
5 key facts about this project
01
Constructed with OSB, the cabins emphasize sustainable building practices by using engineered wood.
02
Large polycarbonate windows enhance natural light and provide expansive views of the surrounding landscape.
03
The hexagonal design allows for efficient space utilization while integrating seamlessly with the terrain.
04
Manual water capture systems promote eco-friendly practices and resource management for users.
05
Shared communal spaces foster social interaction among trekkers while preserving privacy in sleeping areas.

The "Cabins Ambar Trekking" project is a thoughtfully designed series of twelve cabins installed along a 530 km trekking route in Latvia. Each cabin is strategically located approximately every 44 km to provide necessary shelter and rest for trekkers traversing this scenic path. The architectural concept centers around the natural element of amber, reflecting local geography while serving a practical function in supporting outdoor exploration.

Architecturally, the cabins are characterized by their geometric form, featuring hexagonal and triangular structures that harmonize with the surrounding landscape. This distinct design allows for optimal natural light entry, maximizing user comfort while enhancing energy efficiency. The cabins integrate modern living amenities within a compact footprint, balancing user needs with environmental responsibility.

Sustainable material choices are a critical aspect of the project. The core structure utilizes oriented strand board (OSB) for its walls and framework, promoting durability while maintaining an eco-friendly approach. Additionally, polycarbonate materials in the roofing and window structures ensure optimal light diffusion and insulation. Galvanized steel components contribute to the structural integrity of the design, particularly in elements like gutters and chimneys. The careful selection of these materials underlines the project’s commitment to both sustainability and functionality.

Unique Design Approaches

One of the most notable features of the "Cabins Ambar Trekking" project is its integration of solar lighting solutions and water management systems. Each cabin employs a Solutube system designed to capture and distribute natural light effectively throughout the interior. Furthermore, water capture systems allow for rainwater utilization, ensuring that the cabins maintain a low ecological footprint while providing basic amenities for users. The design considers user interaction with sustainable practices; for example, dry-bath facilities and manual water pumping systems facilitate responsible resource usage.

The aesthetic flexibility within the design allows for color variations that respond to environmental changes, reinforcing the connection between the structures and their natural surroundings. This dynamic characteristic enhances the visual identity of the project while ensuring it aligns with the local context.

Functional and Design Elements

The layout of each cabin supports a clear division of space. The design includes three primary zones: public areas for social interaction, private sleeping quarters, and service areas equipped with essential amenities. The public zone encourages communal activities, while the private areas ensure comfort and rest for guests. The arrangement of windows, strategically placed to capture views of the Baltic Sea and nearby forests, further blurs the boundaries between indoor and outdoor environments.

Overall, the "Cabins Ambar Trekking" project exemplifies how thoughtful architectural design can enhance user experience while respecting the environment. The project’s adherence to sustainable practices, use of local materials, and innovative design approaches make it a noteworthy example in contemporary architecture.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
