Sustainable Lodging Crafted from Green Roofing and Curvilinear Timber Structures

Project in-detail

Crafted with modular timber structures and a green roofing system, the design seamlessly integrates into the Icelandic landscape while serving as a dual-purpose accommodation and visitor center.
5 key facts about this project
01
Integrates a green roofing system to enhance insulation and promote local biodiversity.
02
Constructed using modular systems for flexibility and ease of assembly.
03
Incorporates a bent A-frame design that optimizes natural light and airflow.
04
Features charred wooden shingles for enhanced durability and aesthetic appeal.
05
Emphasizes geological integration by aligning structures with the natural topography.

The Grjótgjá Caves architectural project exemplifies a focused approach to creating functional and sustainable structures within a challenging geological context. This project is designed to serve both as accommodations for visitors and as a visitor center, emphasizing a connection with the natural environment of Iceland. The architecture integrates harmoniously into the landscape, addressing not only aesthetic values but also operational efficiency and environmental sustainability.

The project's primary function revolves around providing overnight lodging and educational facilities for those interested in exploring the unique geology of the area. The design enables visitors to engage with the surrounding landscape while ensuring comfort and utility. Structures are strategically placed to minimize their visual impact while maximizing exposure to natural light and airflow.

Sustainable Design and Material Choices

The architectural approach in this project stands out through its commitment to sustainability. Utilizing locally sourced materials reduces transportation costs and environmental impact. Key materials include glass, steel, concrete, wood, and green roofing systems. The use of glass not only allows for natural light penetration but also creates a visual connection between indoor spaces and the external environment. Steel provides structural support while maintaining the overall modern aesthetic. Concrete is used in foundational elements to ensure durability, while wood offers warmth and a natural feel to interior spaces. The green roofing system contributes to insulation and promotes local biodiversity.

Integration with Landscape

A distinct characteristic of the Grjótgjá Caves project is its integration with the surrounding landscape. Pathways and outdoor spaces are designed to enhance visitor navigation and experience while ensuring minimal disruption to the natural ecosystem. The building layout fosters a relationship with the topography, with sleeping pods and communal spaces oriented to capture views of the landscape. The design encourages exploration and engagement with the geological features that define the site, reaffirming the connection between architecture and nature.

Modularity and Flexibility

Further unique elements of the project include its modular design. The components are designed for easy assembly and disassembly, promoting flexibility in construction and adaptation to varying site conditions. This modularity facilitates cost-effective building practices and allows for future modifications as needed. Each building unit is conceived as a standalone module capable of accommodating different functions, thereby maximizing efficiency and utility.

For those interested in delving deeper into the architectural design of Grjótgjá Caves, reviewing the architectural plans, architectural sections, and specific architectural ideas will provide a comprehensive understanding of the innovative features that define this project. Exploring these details further can enhance appreciation for the thoughtful design approaches that have shaped this unique architectural endeavor.

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.
