04
Adjustable legs ensure stability on uneven terrain, enhancing versatility in various locations.
05
An outdoor platform extends functionality, promoting communal activities in a natural setting.

The Amber Cabin is an architectural design project that melds innovative construction techniques with a deep respect for the natural environment. Situated in a forested area along the Baltic Sea, this cabin serves as a multifunctional space for trekkers, combining communal living with individual reflection. Its design is a modern interpretation of the organic forms associated with amber, seamlessly integrating the structure into the surrounding landscape.

The cabin’s primary function is to provide shelter and a gathering space for individuals seeking a retreat in nature. Its design fosters interaction among users while also promoting a sense of tranquility and solitude. The architectural approach emphasizes sustainability, utilizing materials that minimize environmental impact while maximizing energy efficiency.

The Amber Cabin’s structure features a distinctive spherical shape, inspired by the natural form of amber stones. This unique geometry not only enhances the cabin’s aesthetic appeal but also optimizes internal light. The outer shell is constructed from translucent polycarbonate panels that filter light, creating a warm, inviting atmosphere. Internally, the cabin hosts a communal living area designed to accommodate several hammocks, allowing occupants to engage in social interactions or enjoy solitary moments.

One notable aspect of the Amber Cabin is its prefabrication process, which simplifies assembly on-site. Each component is designed for easy transport and quick assembly, making it suitable for various terrains. Adjustable legs ensure stability on uneven ground, further attesting to the design’s adaptability.

The incorporation of a solar panel system underscores a commitment to sustainability, enhancing the cabin's self-sufficiency. This renewable energy source allows the cabin to function independently, further reinforcing its role as a retreat free from the conventional energy grid.

Another significant component is the outdoor platform that extends from the cabin, acting as an additional living area. This space is designed for communal activities, such as cooking and socializing around a fire, creating a connection between the indoor and outdoor environments.

The Amber Cabin stands out due to its holistic approach to architecture. While many cabins focus solely on functionality, this project carefully considers how design impacts user experience and environmental interaction. The integration of natural materials, adaptable construction methods, and an emphasis on communal spaces offers an enriching experience that encourages connection with nature.

For those interested in a deeper exploration of the Amber Cabin, reviewing its architectural plans, sections, and overall design concepts can provide valuable insights into the project's innovative approach and execution. This analysis invites further inquiry into the cabin's architectural ideas and their implications for future designs.

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.
