Basalt Walls and Thatch Roofs Forming a Sustainable Retreat Amid Volcanic Landscapes

Project in-detail

Utilizing locally sourced basalt and a thatched roof, the retreat seamlessly integrates into the sweeping volcanic landscape while providing sustainable residential spaces.
5 key facts about this project
01
Utilizes locally sourced basalt to enhance thermal efficiency and aesthetic integration with the landscape.
02
Features a thatched roof for natural insulation and harmony with the environment.
03
Incorporates cross-laminated timber for structural integrity and reduced carbon footprint.
04
Designed with panoramic window placements to optimize views of the northern lights.
05
Employs passive heating strategies through thermal mass for year-round comfort.

The "Out of the Hill" project is an architectural design located near Lake Myvatn, consisting of structures that harmonize with the surrounding volcanic landscape. The project reflects a commitment to integrating human habitation within the natural environment, utilizing local materials and passive design strategies to optimize functionality and sustainability.

The architectural design emphasizes communal and private living spaces, establishing a balance between social interaction and individual retreats. Key areas include expansive public spaces designed for gatherings, with careful considerations for natural light and vistas. In addition, private areas such as bedrooms provide personalized perspectives of the landscape, enhancing the occupants’ connection to the environment.

Unique Design Approaches

One of the distinguishing features of the project is its material selection. The incorporation of local basalt as a primary building material connects the structure to its geological context. Basalt not only offers durability but also contributes to thermal efficiency, acting as a thermal mass to regulate temperature. The use of glulam (glued laminated timber) in the structural framework facilitates wide spans, creating open interior spaces that are warm and inviting.

The roof utilizes natural thatching, aligning with the project’s sustainability goals. This method not only enhances insulation but also integrates seamlessly with the natural surroundings, while concrete is selectively employed for foundational elements. The thoughtful arrangement of materials supports the performance and longevity of the structures while minimizing environmental impact.

Sustainable strategies are a core aspect of the design. The orientation of the building maximizes solar gain in winter while controlling heat in summer. A focus on passive temperature control through thermal mass and carefully positioned eaves demonstrates an approach that prioritizes energy efficiency. Rainwater management strategies are integrated into the topography to prevent erosion and maintain ecological balance.

Functional Areas and Architectural Details

The "Out of the Hill" project comprises a blend of communal and private spaces, carefully designed to facilitate interaction while maintaining privacy. The living areas, including a kitchen and gathering spaces, are central to the layout, with large windows providing unobstructed views of the stunning landscape. Bedrooms are strategically placed to ensure occupants can experience specific natural phenomena, such as the aurora borealis.

The design features an emphasis on accessibility and inclusivity. The layout accommodates mobility considerations, ensuring ease of movement throughout the space.

For those interested in exploring the architectural vision behind the "Out of the Hill" project further, detailed architectural plans, sections, and design elements are available for review. Understanding the architectural ideas and strategies embodied in this project enhances comprehension of its significance within the context of modern 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.
