The Hollow Cabin is a contemporary architectural project located in Iceland, near Myvatn Nature Baths. Designed to harmonize with the unique landscape of the region, this structure draws inspiration from traditional Icelandic turf houses, adapting their principles to modern needs. The project serves as a communal space designed for gatherings, education, and interaction while addressing the challenges posed by the harsh climatic conditions in Iceland.

The Hollow Cabin features a partially submerged design that integrates with the surrounding topography. This design approach minimizes visual disruption and energy consumption, while also creating a sense of intimacy with the natural environment. The building's orientation takes advantage of scenic views and natural light, enhancing the spatial experience for users.

The use of sustainable materials reflects consideration for local resources and environmental impact. Primary materials include a green roof to improve insulation, sand cement screed for the walls, and cross-laminated timber for structural support. These elements contribute to energy efficiency while ensuring durability against Iceland's climatic elements. Additionally, the building incorporates areas for social interaction around strategically placed fireplaces, reinforcing community ties among visitors.

Innovation is evident in the unique zoning of the interior spaces, which distinguishes public and private areas while maintaining a cohesive flow throughout the building. The architecture's design considers various user experiences, ensuring accessibility and comfort for all visitors. The careful integration of pathways, parking, and adjacent natural features further enhances the overall functionality of the site.

Architectural plans demonstrate how the building’s layout promotes environmental interaction and community engagement. Architectural sections illustrate the relationship between the structure and its landscape, showcasing how the design embraces the terrain rather than imposing on it.

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.
